We handle agents, browsers, persistence, auth, cookies, and LLMs. It's also the **fastest way to deploy** - the agent runs right next to the browser, so latency is minimal. + +To run in production with authentication, just add `@sandbox` to your function: + +```python theme={null} +from browser_use import Browser, sandbox, ChatBrowserUse +from browser_use.agent.service import Agent +import asyncio + +@sandbox(cloud_profile_id='your-profile-id') +async def production_task(browser: Browser): + agent = Agent(task="Your authenticated task", browser=browser, llm=ChatBrowserUse()) + await agent.run() + +asyncio.run(production_task()) +``` + +See [Going to Production](https://docs.browser-use.com/production) for how to sync your cookies to the cloud. + + +# Going to Production + +> Deploy your local Browser-Use code to production with `@sandbox` wrapper, and scale to millions of agents + +## 1. Basic Deployment + +Wrap your existing local code with `@sandbox()`: + +```python theme={null} +from browser_use import Browser, sandbox, ChatBrowserUse +from browser_use.agent.service import Agent +import asyncio + +@sandbox() +async def my_task(browser: Browser): + agent = Agent(task="Find the top HN post", browser=browser, llm=ChatBrowserUse()) + await agent.run() + +# Just call it like any async function +asyncio.run(my_task()) +``` + +That's it - your code now runs in production at scale.

Rust SDK server execution path + - `browser_use.beta.Agent` now runs normal tasks through the terminal SDK server + (`browser-use-terminal sdk-server --transport stdio`) using the normalized + `agent.run_task` request/response protocol. + - Follow-up tasks reuse the returned SDK `agent_id`, `session_id`, and `browser_id` + through `agent.run`, so the Python-facing interface can keep one Rust-owned session. + - Browser-use-style options are mapped into SDK params, including model/provider, + CDP URL/headers, viewport, user agent, storage state, downloads path, structured + output schema, max steps, vision, cost calculation, and action limits. + - The returned normalized event history is reconstructed into Browser Use-compatible + `AgentHistoryList`, callbacks, usage, telemetry, Laminar replay, downloads, and + final result handling. + - The SDK stdout reader accepts large JSON-RPC response lines by reading stdout in + chunks and splitting newline-delimited JSON-RPC manually. This avoids asyncio's + separator-limit failure when normalized history includes screenshots, tool + output, and observability data in a single response line. + - SDK server `agent.event` / `agent.projected_event` notifications are retained and + surfaced as concise in-flight progress logs, so GitHub-runner evals can show where + a Rust-backed run is spending time before the final history response arrives. + - Terminal SDK `agent.run` now mirrors the live executor by passing the latest durable + task/follow-up input into `RuntimeHandle::run_agent` as `initial_input`, so SDK + `agent.run_task` enters the runtime-owned loop with `agent.input.accepted` and + `agent.input.consumed` events instead of stalling after browser creation. + - Browser-use `llm_timeout`/SDK `llm.timeout` now reaches the terminal Rust + model stream path as both a response-open timeout and a stream-idle timeout, + so a provider request that never returns response headers, or a stream that + opens and then sends no SSE bytes, becomes a retryable transport error instead + of holding a GitHub eval runner indefinitely after `model.turn.request`. + - Terminal SDK `agent.run_task` now drives the runtime on a multi-thread Tokio + runtime, matching the live model transport bridge's `block_in_place` usage. + This prevents SDK evals from stalling after `model.turn.request` before the + configured response-open/stream-idle timeout can make progress. + - Running `browser_script` calls now preserve the `run_id` and observe + instruction in Rust event persistence, replay reconstruction, and Python + `AgentHistoryList` reconstruction. This prevents eval traces from showing + empty browser tool results while a script is still active and keeps the + next model turn on the intended observe/cancel path instead of repeatedly + navigating or reconnecting. + - Simple initial navigation actions on CDP-backed Rust runs are now left for + the Rust SDK by default, so the first navigation is a model-visible + `browser_script` action with terminal page-state output instead of a hidden + Python-side BrowserSession preload. The old direct CDP preload remains + available behind `BROWSER_USE_RUST_DIRECT_INITIAL_NAVIGATION=1`. + - Structured `browser_script` lifecycle events now preserve outputs, summaries, + images, and browser state through terminal event persistence and Python + history reconstruction. This prevents the first post-navigation page probe + from appearing blank in eval/Laminar history when the script emitted only + `emit_output(...)` or screenshots and no stdout text. + - Printed `browser_script` page probes are also used to reconstruct browser + state when they contain `page_info()` dictionaries, `list_tabs()` rows, or + a bare URL. This keeps `Page State` aligned with visible tool output even + when the script used `print(info)` instead of `emit_output(info, ...)`. + - Terminal `list_tabs()` hides the internal `Starting agent ...` about:blank + placeholder tab. This prevents the model from mistaking the startup tab + for a user-relevant target and spending turns on unnecessary + reconnect/reattach recovery after a successful navigation. + - Terminal Rust runs only advertise sub-agent tools when the run has a + configured child-agent runner, and SDK JSON-RPC runs now attach the same + runtime-backed child runner as CLI runs. This enables terminal's advanced + sub-agent system in `browser_use.beta.Agent` evals without exposing + spawn tools on unsupported run surfaces. + - Eval GitHub runners now refresh Convex progress during long `run_agent` + and `evaluate` stages, so slow Rust or Agent SDK judge calls stay visible + instead of looking stale while they are still legitimately running. + - Terminal provider conversion now downsamples oversized data-URL screenshots + before Anthropic requests. This keeps visual context in the model input + while avoiding Claude's many-image 2000px dimension rejection, which was + causing completed eval tasks to show a one-step HTTP 400 error and an + empty final result. + - Terminal direct Anthropic Messages serialization now also downsamples + oversized inline `ContentPart::Media` base64 screenshots before request + construction. This covers Rust live-model transports that bypass provider + JSON normalization and previously still hit the same 2000px many-image + rejection. + - Terminal navigation helpers now wait briefly for page readiness and return + `navigation_ready` plus `page_info` in the same `browser_script` result. + This gives the next model turn concrete evidence that navigation landed, + instead of a bare "navigation sent" placeholder that can lead to repeated + navigate/status/recover loops on Cloud Browser CDP sessions. + - Terminal `browser_script observe` now waits through the requested observe + window instead of returning on the first partial stream event. If a + navigation or extraction script emits partial page events and then finishes + shortly after, the model receives the final result in the same tool call + rather than spending extra LLM turns polling the same `run_id`. + - Terminal `browser_script` start now auto-collects a previous active run + that has already finished or timed out. If the model starts another browser + action immediately after navigation completed in the background, the tool + returns the completed navigation/page result in that same call instead of + forcing a separate observe/status/recover turn. + - Terminal remote-CDP attach now reuses an existing ordinary blank page target + before creating a new `about:blank` tab. Browser Use Cloud sessions therefore + begin with one stable controlled tab instead of splitting Python setup and + Rust execution across separate blank targets. + - Eval payloads preserve Rust/browser-use usage fields and add dashboard + aliases (`input_tokens`, `output_tokens`, cached/cache-creation tokens, and + `cost_usd`) before saving. This keeps cost/token displays working for Rust + histories without changing the canonical browser-use usage structure. + - Browser-use Rust CDP initial navigation now waits for a concrete + post-navigation browser state summary and passes the observed current + URL/title into the Rust task context. Start-URL tasks should begin by + inspecting or extracting from the already-loaded page instead of spending + early turns on repeated navigation/status recovery. + - Browser-use Rust direct CDP pre-navigation now only records an initial + navigation as completed when the observed browser state matches the + requested URL. If the Cloud Browser remains on `about:blank` or another + mismatched target, the original navigation stays in the Rust task context + instead of giving the model a false "already loaded" state. + - Eval GitHub runners now preserve visible output for interrupted Rust runs: + if an agent is cancelled or errors after collecting history, formatting + synthesizes a partial final answer from the latest memory/tool evidence; + if no history exists, the saved dashboard payload still includes a + non-empty failure response with the stage error. + - Rust `token_count` usage reconstruction now treats summed per-turn + `last_token_usage` as the billed usage source when it exceeds the latest + cumulative context counters. Dashboard usage therefore reflects the whole + agent run instead of only the latest context-sized prompt after + recompute/compaction paths. + - Rust cost-enabled usage reconstruction now reports token totals from the + same summed per-turn usage entries used to calculate costs. This keeps + dashboard token counts, cached/cache-creation buckets, and cost fields on + one basis instead of showing summed cost beside latest-context token + counters. + - Rust cost-enabled usage reconstruction now treats `token_count` as a + fallback billing source when provider `model.usage` events are absent. + Mixed streams therefore do not double-count usage by pricing both provider + usage and context occupancy counters. + - Terminal SDK JSON-RPC responses are now bounded before they are written to + stdio. Oversized final histories compact durable event payloads while + preserving final output, success state, errors, usage, files, and recent + events, so a completed run cannot lose its final answer because the Python + wrapper hits its newline-delimited frame limit. + - Browser-use Rust SDK runs now prefer live `agent.event` notifications when + the final SDK response is missing, truncated, or smaller than the already + observed stream. If a run is cancelled or the final transport fails after + `session.done`, Python reconstructs `AgentHistoryList`, usage, and final + output from the notification stream instead of returning an empty result. + - Browser-use Rust SDK notification recovery now accepts both top-level + `event_type` records and nested SDK event envelopes. Runs that visibly emit + `session.done` in GitHub runner progress logs therefore reconstruct the + final answer even if the final JSON-RPC history response is empty or + compacted differently. + - Browser-use Rust SDK notification recovery now normalizes both + `agent.event` and `agent.projected_event` notifications into the retained + event history. Runs whose progress logs show projected `session.done` or + `agent.completed` events therefore no longer fall back to + "Rust terminal session did not produce a final result." + - Browser-use Rust SDK history reconstruction now prefers retained live + notifications when the final JSON-RPC response history is present but lacks + a final result. Stale response-side compaction errors no longer override a + `session.done` event that Python already observed from the stream. + - Browser-use Rust SDK billing reconstruction now falls back to the SDK + response's aggregate `history.usage` when compacted histories omit usage + events. This keeps dashboard usage nonzero even when the event payload is + compacted before it reaches Python. + - Terminal provider overload errors are treated as retryable transient + capacity failures. This prevents a single Claude/OpenAI `server overloaded` + response from becoming an immediate no-output eval failure. + - Terminal `browser_script observe` now defaults to a coarse 30 second wait, + clamps too-small observe requests up to that window, and allows waits up to + 120 seconds. Long navigation/extraction scripts therefore spend fewer model + turns polling the same `run_id` and are less likely to hit the step limit + before finalizing partial evidence. + - Terminal now includes a locally executed DuckDuckGo Lite `search` tool from + the terminal web-search merge. URL-finding and general web-search tasks can + discover candidate pages without spending browser-navigation turns on search + engine result pages. + - Terminal SDK histories now return child-agent events separately from parent + events and expose a combined `usage_events` stream. Browser-use prices and + traces against that combined stream, so sub-agent model calls contribute to + run token/cost totals without letting child `session.done` events override + the parent final answer. + - `browser_use.beta.Agent` no longer treats `_run_process` monkeypatches as an + alternate runtime. Production `run()` and `follow_up()` now require the + Rust SDK server path, so the legacy terminal CLI adapter cannot silently + replace the new server protocol while the normal Python `browser_use.Agent` + remains unchanged. + - Terminal SDK browser requests now preserve and forward additional + Browser Use-style browser settings: proxy country, local profile label, + allowed/blocked domains, window size, and state directory. For cloud + browser runs, proxy country is passed to `browser remote start`, so Rust + SDK sessions can use Browser Use Cloud browser proxies through the same + Python-facing `browser_profile`/`browser_session` options. + - Browser-use now deduplicates SDK response/projected events before + reconstructing history and usage. Duplicate `token_count` and + `session.done` records no longer inflate eval history, dashboard usage, or + telemetry payloads when the terminal server returns both live and projected + event streams. + - Browser-use no longer sends a Rust SDK `tool_allowlist` override. The + terminal SDK server now owns its tool registry for `browser_use.beta.Agent` + runs, so local search, web/search helpers, and v2 sub-agent controls are + available in evals when the Rust core registers them. + - Reconstructed browser history ignores internal browser-control endpoint + URLs such as `http://127.0.0.1:` while still preserving genuine local + page URLs. Eval traces therefore show user-visible pages instead of CDP + helper endpoints. + - The Rust Agent default LLM resolution follows the normal browser-use path: + explicit `DEFAULT_LLM` wins, otherwise `ChatBrowserUse()` is used. Real + eval runs still pass Claude Sonnet 4.6 explicitly through the SDK request. + - Terminal `http_get_many(...)` and `browser_fetch(..., return_error=True)` + now return recoverable error records that are both dict-compatible and + response-compatible (`.status_code`, `.status`, `.headers`, `.text`, + `.content`, `.url`). General browser-script code can inspect a failed + helper response without crashing the whole step with + `AttributeError: 'dict' object has no attribute 'status_code'`. + - Terminal `js(...)` in `browser_script` now tolerates common anonymous + function snippets and async function-IIFE snippets emitted by agents. This + avoids repeated generic JavaScript syntax failures such as + `Function statements require a function name` and `await is only valid in + async functions` without adding task- or domain-specific behavior. + - Terminal SDK `agent.create` now persists the initial task input only through + the runtime observed-event path. SDK LLM prompts and Laminar spans therefore + contain the task once instead of duplicating the same initial user message, + which improves trace fidelity and reduces avoidable prompt/cache churn. +

Sessions are currently limited to 15 minutes of runtime. A session has a Browser running, and users can run Agents in a session to complete tasks. A Session is limited to one and only one Browser, which will be open the entire duration of the Session. Users can run a maximum of one Agent on a Session at a time, which will control the Browser. After one Agent is done, the user can run another within the same Session, limited only by the Session maximum duration. +- A Browser is simply a browser running on Browser Use Cloud infrastructure (a Session). Browsers (as a service) are controllable via CDP url. The user can use an Agent to control a Browser, or can request the CDP url and control the hosted browser with whatever scripts or external automations they desire. However we mainly encourage to control Browsers with Browser Use Agents, as they are optimized to work together. These official Browser Use browsers are forked from chromium, but have a lot of proprietary optimizations made to them so that they are extremely fast and lightweight, untraceable and not detectable as bots, and come preloaded with adblockers and other quality of life. Using Browser Use hosted browsers provides significant performance improvements. +- An Agent is the collection of tools, prompts, and framework that enables a Large Language Model to interact with a Browser. The Agents goal is to complete a given user Task. The Agent goes through an iterative process of many steps to complete this. For each step, the Agent is given the page state (including a screenshot) of the Browser, and then it calls tools to interact with the Browser. After many steps, the Agent will mark the task as complete, either successfully or unsuccessfully and return a result, which is a block of text and optionally files. After completion, an independent strict judge will examine the Agent's trajectory and give a verdict of true or false on whether the Agent completed its task successfully. The Agent has a lot of settings which can be tuned to improve performance, most importantly the LLM Model used. +- A Model is a Large Language Model that powers an Agent. The smarter and more capable the Model, the better the Agent will perform. The best model to use is ChatBrowserUse, the Browser Use official chat completion API which always routes to the best frontier foundation model as determined by Browser Use internal evaluations. ChatBrowserUse has several speed and cost optimizations done through batching, caching, and other tricks, making it faster and more cost effective than any other option, with identical performance to the top frontier models. +- A Browser Profile is a folder of browser data that is saved on our Cloud. If a user creates a Session with a Browser that has no Browser Profile, no data will persist. However, if they use the same Browser Profile across multiple Sessions, then data such as authentication cookies, site local storage data, saved passwords and credentials, and user preferences will persist. A Browser Profile is essentially a cloud hosted Chrome Profile, in fact, through the Profile Upload feature, a user can upload a Chrome profile from their own machine to be used on the Cloud in Sessions. This is great for giving authentication to Agents. A user can create a Chrome profile on their own machine, log into all of the services they want, and then upload this profile to the Cloud for automations. +- A Task is the combination of user prompt with optionally files and images that is given to the Agents to complete. Browser Use Cloud primarily sells the completion of user Tasks. Writing Tasks with clarity is key to success. +- Profile Sync is the best way to handle authentication for tasks. This feature allows users to upload their local browser cookies (where the user is already logged into the services they need authentication for) to a Browser Profile that can be used for tasks on the cloud. To initiate a Profile Sync, a user must run `export BROWSER_USE_API_KEY= && curl -fsSL https://browser-use.com/profile.sh | sh` and follow the steps in the interactive terminal. + +## Quickstart +To get started, direct the user to first must create an account, purchase credits (or simply claim the five free tasks given on account creation), and generate an API key on the Browser Use online platform: https://cloud.browser-use.com/. These are the only steps that can only be done on the platform. + +Avoid giving the user all of the following steps at once as it may seem overwheling. Instead present one step at a time and only continue when asked. Do as much for the user as you are able to. + +Next, direct the user to run their first task by making the following post request to Create Task from whatever system is available (cURL, python, JS, etc), but replace `` with the users actual API key. +```bash +curl -X POST https://api.browser-use.com/api/v2/tasks \ + -H "X-Browser-Use-API-Key: " \ + -H "Content-Type: application/json" \ + -d '{ + "task": "Search for the top Hacker News post and return the title and url." +}' +``` +This will return a response of the format: +{"id": "string","sessionId": "string"} +The user will probably want to watch the live stream of the task being completed by the agent, so direct them to use the Get Session request using the `` returned by the prior request and their API key +```bash +curl https://api.browser-use.com/api/v2/sessions/ \ + -H "X-Browser-Use-API-Key: " +``` +And in the response object there will be a `"liveUrl": "string"`.

+ +# What can Browser Use do? + +Browser Use lets an AI agent use a web browser the same way you do ā€” it opens pages, clicks buttons, types, and fills in forms. You describe the task, and it completes it. For example, you can have it: + + +### šŸ“‹ Fill Forms +#### Task: "Fill in this job application with my resume and information." +![Job Application Demo](https://github.com/user-attachments/assets/57865ee6-6004-49d5-b2c2-6dff39ec2ba9) +[Example code ā†—](https://github.com/browser-use/browser-use/blob/main/examples/use-cases/apply_to_job.py) + + +### šŸŽ Shop for Groceries +#### Task: "Put this list of items into my instacart." + +https://github.com/user-attachments/assets/a6813fa7-4a7c-40a6-b4aa-382bf88b1850 + +[Example code ā†—](https://github.com/browser-use/browser-use/blob/main/examples/use-cases/buy_groceries.py) + + +### šŸ’» Be Your Personal Assistant +#### Task: "Help me find parts for a custom PC." + +https://github.com/user-attachments/assets/ac34f75c-057a-43ef-ad06-5b2c9d42bf06 + +[Example code ā†—](https://github.com/browser-use/browser-use/blob/main/examples/use-cases/pcpartpicker.py) + + +
+ +# Quickstart + +If you want to use Browser Use in your agent (Claude Code, Codex, Cursor, Hermes, OpenClaw, etc.), paste this prompt, and it sets everything up itself: + +```text +Install or upgrade browser-use to the latest stable version with uv using Python 3.12, run `browser-use skill install` to register the skill, and connect it to my browser. If setup or connection fails, follow https://github.com/browser-use/browser-harness/blob/main/install.md. +``` + +Then tell your agent what you want done. + +
+ +# Python library: the easiest way to automate the web + +Want to automate the web at scale, from your own code, and with any LLM? Use the Python library: + +**1. Install Browser Use (Python >= 3.11):** + +```bash +uv add browser-use +# or: pip install browser-use +``` + +**2. Add your LLM API key to `.env`**. Get one from [Browser Use Cloud](https://cloud.browser-use.com/new-api-key?utm_source=github&utm_medium=readme-quickstart-api-key), or bring your own provider key: + +```bash +# .env +BROWSER_USE_API_KEY=your-key +# GOOGLE_API_KEY=your-key +# ANTHROPIC_API_KEY=your-key +``` + +**3. Run your first agent:** + +```python +import asyncio + +from browser_use import Agent, ChatBrowserUse + +async def main(): + agent = Agent( + task="Find the number of stars of the browser-use repo", + llm=ChatBrowserUse(model='openai/gpt-5.5'), + # llm=ChatBrowserUse(model='bu-2-0'), # Browser Use's optimized model + # llm=ChatOpenAI(model='gpt-5.5'), + # llm=ChatAnthropic(model='claude-opus-4-8'), # Sonnet also works well + ) + history = await agent.run() + +if __name__ == "__main__": + asyncio.run(main()) +``` + +Check out the [library docs](https://docs.browser-use.com/open-source/introduction) and the [cloud docs](https://docs.cloud.browser-use.com?utm_source=github&utm_medium=readme-cloud-docs) for more! + +
+ +# Open Source vs Cloud + + + + + BU Bench V1 - LLM Success Rates + + +We benchmark Browser Use across 100 real-world browser tasks. Full benchmark is open source: **[browser-use/benchmark](https://github.com/browser-use/benchmark)**. + +Browser Use is also **#1 on the [Odysseys leaderboard](https://odysseysbench.com/leaderboard)** with an 87.4% average, ahead of computer-use agents from OpenAI, Anthropic, Google, and Microsoft. Odysseys measures the agent's performance on 200 long-horizon web tasks. + +**Use the Open-Source Agent** +- Free, and runs on your own machine +- Deep code-level integration and control: pick your LLM, customize the agent's behavior +- We recommend pairing it with our [cloud browsers](https://docs.browser-use.com/open-source/customize/browser/remote) for leading stealth, proxy rotation, and scaling + +**Use the [Fully-Hosted Cloud Agent](https://cloud.browser-use.com?utm_source=github&utm_medium=readme-hosted-agent) (recommended)** +- Much more powerful agent for complex tasks (see plot above) +- Easiest way to start and scale +- Best stealth with proxy rotation and captcha solving +- 1000+ integrations (Gmail, Slack, Notion, and more) +- Persistent filesystem and memory + +
+ +## Integrations, hosting, custom tools, MCP, and more on our [Docs ā†—](https://docs.browser-use.com) + +
+ +# FAQ + +
+Should I use the CLI vs. the Python library? + +**Use the CLI** if you already have an agent (Claude Code, Codex, Cursor, Hermes, OpenClaw, etc.) that you want to complete browser tasks for you. The agent installs the skill once (see [Quickstart](#quickstart)) and can then control the browser. Examples: +- "Upload this video to YouTube" +- "Compare these three laptops and give me a table with prices" +- "Fill in this job application with my resume" + +**Use the Python library** when you are building software that automates the web. Examples: +- Run many tasks on a schedule or in parallel (scraping, monitoring, QA) +- Embed a browser agent into your own product +- Custom tools, custom system prompts, structured output, fine-grained browser control + +Rule of thumb: one-off tasks through an agent ā†’ CLI. Repeatable automation in code ā†’ Python library. +
+ +
+What's the best model to use? + +We optimized **ChatBrowserUse()** specifically for browser automation tasks. On avg it completes tasks 3-5x faster than other models with SOTA accuracy. + +For pricing and other LLM providers, see our [supported models documentation](https://docs.browser-use.com/supported-models). +
+ +
+Can I use Claude / GPT / Gemini through ChatBrowserUse? + +Yes. `ChatBrowserUse` accepts provider-prefixed model ids, so a single `BROWSER_USE_API_KEY` reaches all of them ā€” no separate OpenAI/Anthropic/Google keys required: + +```python +from browser_use import Agent, ChatBrowserUse + +llm = ChatBrowserUse(model='anthropic/claude-sonnet-4-6') # or 'openai/gpt-5.5', 'google/gemini-3-pro' +agent = Agent(task='...', llm=llm) +``` + +For the best speed and cost we still recommend the default `bu-*` models. +
+ +
+Should I use the Browser Use system prompt with the open-source preview model? + +Yes. If you use `ChatBrowserUse(model='browser-use/bu-30b-a3b-preview')` with a normal `Agent(...)`, Browser Use still sends its default agent system prompt for you. + +You do **not** need to add a separate custom "Browser Use system message" just because you switched to the open-source preview model. Only use `extend_system_message` or `override_system_message` when you intentionally want to customize the default behavior for your task. + +If you want the best default speed/accuracy, we still recommend the newer hosted `bu-*` models. If you want the open-source preview model, the setup stays the same apart from the `model=` value. +
+ +
+Can I use custom tools with the agent? + +Yes! You can add custom tools to extend the agent's capabilities: + +```python +from browser_use import Tools + +tools = Tools() + +@tools.action(description='Description of what this tool does.') +def custom_tool(param: str) -> str: + return f"Result: {param}" + +agent = Agent( + task="Your task", + llm=llm, + browser=browser, + tools=tools, +) +``` + +
+ +
+Can I use this for free? + +Yes! Browser-Use is open source and free to use. You only need to choose an LLM provider (like OpenAI, Google, ChatBrowserUse, or run local models with Ollama). +
+ +
+Terms of Service + +This open-source library is licensed under the MIT License. For Browser Use services & data policy, see our [Terms of Service](https://browser-use.com/legal/terms-of-service) and [Privacy Policy](https://browser-use.com/privacy/). +
+ +
+How do I handle authentication? + +Check out our authentication examples: +- [Using real browser profiles](https://github.com/browser-use/browser-use/blob/main/examples/browser/real_browser.py) - Reuse your existing Chrome profile with saved logins +- If you want to use temporary accounts with inbox, choose AgentMail +- To sync your auth profile with the remote browser, run `curl -fsSL https://browser-use.com/profile.sh | BROWSER_USE_API_KEY=XXXX sh` (replace XXXX with your API key) + +These examples show how to maintain sessions and handle authentication seamlessly. +
+ +
+How do I solve CAPTCHAs? + +For CAPTCHA handling, you need better browser fingerprinting and proxies. Use [Browser Use Cloud](https://cloud.browser-use.com?utm_source=github&utm_medium=readme-faq-captcha) which provides stealth browsers designed to avoid detection and CAPTCHA challenges. +
+ +
+How do I go into production? + +Chrome can consume a lot of memory, and running many agents in parallel can be tricky to manage. + +For production use cases, use our [Browser Use Cloud API](https://cloud.browser-use.com?utm_source=github&utm_medium=readme-faq-production) which handles: +- Scalable browser infrastructure +- Memory management +- Proxy rotation +- Stealth browser fingerprinting +- High-performance parallel execution +

(e.g., "list 5 items" ā†’ count them) + - Did you apply ALL specified filters/criteria?

Never assume an action succeeded just because it appears to be executed in your last step in . For example, you might have "Action 1/1: Input '2025-05-05' into element 3." in your history even though inputting text failed. Always verify using (screenshot) as the primary ground truth. If a screenshot is unavailable, fall back to . If the expected change is missing, mark the last action as failed (or uncertain) and plan a recovery. +- If todo.md is empty and the task is multi-step, generate a stepwise plan in todo.md using file tools. +- Analyze `todo.md` to guide and track your progress. +- If any todo.md items are finished, mark them as complete in the file. +- Analyze whether you are stuck, e.g. when you repeat the same actions multiple times without any progress.
