# ### ⚡ Running Presenton

You can run Presenton in two ways: Docker for a one-command setup without installing a local dev stack, or the Electron desktop app for a native app experience (ideal for development or offline use).

**Option 1: Electron (Desktop App)**

Run Presenton as a native desktop application. LLM and image provider (API keys, etc.) can be configured in the app. The same environment variables used for Docker apply when running the bundled backend.

Prerequisites: Node.js (LTS), npm, Python 3.11, and uv (for the shared FastAPI backend in servers/fastapi).

- Setup (First Time)

cd electron
  npm run setup:env

This installs Node dependencies, runs uv sync in the FastAPI server, and installs Next.js dependencies. - Run in Development

npm run dev

This compiles TypeScript and starts Electron. The backend and UI run locally inside the desktop window.

- Build Distributable (Optional) To create installers for Windows, macOS, or Linux:

npm run build:all
  npm run dist

Output files are written to electron/dist (or as configured in your electron-builder settings).

For a public macOS DMG outside the Mac App Store, use APPLE_KEYCHAIN_PROFILE="presenton-notary" npm run build:all:mac:signed from electron/ after the one-time Developer ID and notarization setup in docs/macos/dev/direct-distribution.md.

**Option 2: Docker** - Start Presenton Linux/MacOS (Bash/Zsh Shell):

docker run -it --name presenton -p 5001:80 -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest

Windows (PowerShell):

docker run -it --name presenton -p 5001:80 -v "${PWD}\app_data:/app_data" ghcr.io/presenton/presenton:latest

- Open Presenton

Open http://localhost:5001 in the browser of your choice to use Presenton.

Note: You can replace 5001 with any other port number of your choice to run Presenton on a different port number. If you use Docker Compose, set PRESENTON_HTTP_HOST_PORT, for example PRESENTON_HTTP_HOST_PORT=8080 docker compose up production.

# ### ⚙️ Deployment Configurations The lists below match the environment variables forwarded in this repository’s **`docker-compose.yml`** (`production`, `production-gpu`, `development`, and `development-gpu`). Put values in a `.env` file next to the compose file, or export them before `docker compose up`. The Electron app backend can read the same names when run outside Docker. Other optional variables exist in code (for example advanced Mem0 paths, LiteParse runners, or `FAST_API_INTERNAL_URL` when Next.js and FastAPI are not same-origin); they are **not** wired in `docker-compose.yml`. Supported names are discoverable from `servers/fastapi/utils/get_env.py` and the Next.js server utilities under `servers/nextjs/`. #### LLM and API keys - **CAN_CHANGE_KEYS**=[true/false]: Set to **false** if you want to keep API keys hidden and make them unmodifiable. - **LLM**=[openai/deepseek/google/vertex/azure/bedrock/openrouter/fireworks/together/cerebras/anthropic/litellm/lmstudio/ollama/custom/codex]: Select the text **LLM**. - **OPENAI_API_KEY**: Required if **LLM** is **openai**. - **OPENAI_MODEL**: Required if **LLM** is **openai** (default: `gpt-4.1`). - **DEEPSEEK_API_KEY**: Required if **LLM** is **deepseek**. - **DEEPSEEK_MODEL**: Required if **LLM** is **deepseek** (default: `deepseek-chat`). - **DEEPSEEK_BASE_URL**: Optional if **LLM** is **deepseek** (default: `https://api.deepseek.com`). - **GOOGLE_API_KEY**: Required if **LLM** is **google**. - **GOOGLE_MODEL**: Required if **LLM** is **google** (default: `models/gemini-2.0-flash`). - **VERTEX_MODEL**: Required if **LLM** is **vertex** (default: `gemini-2.5-flash`). - **VERTEX_API_KEY**: Optional auth path for **LLM=vertex** (Vertex Express). - **VERTEX_PROJECT** / **VERTEX_LOCATION**: Optional auth path for **LLM=vertex** when using GCP project credentials (do not combine with `VERTEX_API_KEY`). - **VERTEX_BASE_URL**: Optional Vertex gateway/base URL override. - **AZURE_OPENAI_MODEL**: Required if **LLM** is **azure** (deployment/model name). - **AZURE_OPENAI_API_KEY**: Required if **LLM** is **azure**. - **AZURE_OPENAI_API_VERSION**: Required if **LLM** is **azure** (for example `2024-10-21`). - **AZURE_OPENAI_ENDPOINT** / **AZURE_OPENAI_BASE_URL**: At least one is required if **LLM** is **azure**. - **AZURE_OPENAI_DEPLOYMENT**: Optional deployment override for **LLM** is **azure**. - **BEDROCK_REGION**: Optional if **LLM** is **bedrock** (default: `us-east-1`). - **BEDROCK_MODEL**: Required if **LLM** is **bedrock**.

Default **false** (`development` / `production` compose). #### Presentation memory (Mem0 OSS) Mem0 uses local Qdrant + SQLite (OSS); memory is scoped per presentation. By default the Docker runtime now points Mem0 at a local Ollama-compatible LLM endpoint, so it no longer needs an OpenAI key just to initialize. If you want to use OpenAI instead, set `MEM0_LLM_BASE_URL`/`MEM0_LLM_API_KEY` to your OpenAI-compatible endpoint and key. Docker images install the default spaCy model (`en_core_web_sm`) during build so Mem0 can start without extra setup on each run. | Variable | Purpose | | ---------------------------- | ---------------------------------------------------------------------------------------------------------------- | | **MEM0_ENABLED** | **true**/false (compose default **true**). | | **MEM0_LLM_MODEL** | Mem0 LLM model name (compose default **`llama3.1:latest`** or `OLLAMA_MODEL`). | | **MEM0_LLM_API_KEY** | Mem0 LLM API key placeholder for OpenAI-compatible clients (compose default **`ollama`**). | | **MEM0_LLM_BASE_URL** | Mem0 LLM base URL (compose default **`OLLAMA_URL`** or `http://host.docker.internal:11434`). | | **MEM0_DIR** | Root directory (compose default **`/app_data/mem0`**). | | **MEM0_EMBEDDER_PROVIDER** | Embedder backend (compose default **`fastembed`**). | | **MEM0_EMBEDDER_MODEL** | Model id (compose default **`BAAI/bge-small-en-v1.5`**). | | **MEM0_EMBEDDING_DIMS** | Vector size (compose default **384**). | | **MEM0_SPACY_MODEL** | Optional spaCy model override (default **`en_core_web_sm`**). | | **MEM0_REQUIRE_SPACY_MODEL** | Keep as **true** (default). Set to false only if you intentionally want Mem0 to run without spaCy lemmatization. | #### Document parsing (LiteParse) | Variable | Purpose | | ------------------------- | ----------------------------------------- | | **LITEPARSE_DPI** | OCR render DPI (compose default **120**). | | **LITEPARSE_NUM_WORKERS** | Worker count (compose default **1**). | #### Database - **DATABASE_URL**: SQLAlchemy URL; if unset, the app falls back to SQLite under app data. - **MIGRATE_DATABASE_ON_STARTUP**: Compose sets **`true`** for all services so migrations run on startup. #### Image generation These variables match `docker-compose.yml`. **`IMAGE_PROVIDER`** selects the backend (`pexels`, `pixabay`, `gemini_flash`, `nanobanana_pro`, `dall-e-3`, `gpt-image-1.5`, `comfyui`, `open_webui`). Use **OPENAI_API_KEY** for OpenAI image modes and **GOOGLE_API_KEY** for Gemini image modes (same keys as the LLM section). - **DISABLE_IMAGE_GENERATION**=[true/false]: Disable slide image generation. - **IMAGE_PROVIDER**: Provider id (see enum above). - **PEXELS_API_KEY**: Pexels stock images. - **PIXABAY_API_KEY**: Pixabay stock images. - **DALL_E_3_QUALITY**=[standard/hd]: Optional for **dall-e-3** (default `standard`). - **GPT_IMAGE_1_5_QUALITY**=[low/medium/high]: Optional for **gpt-image-1.5** (default `medium`). - **COMFYUI_URL** / **COMFYUI_WORKFLOW**: Self-hosted ComfyUI workflow JSON. - **OPEN_WEBUI_IMAGE_URL** / **OPEN_WEBUI_IMAGE_API_KEY**: Open WebUI–compatible image endpoint. - **OPENAI_COMPAT_IMAGE_BASE_URL** / **OPENAI_COMPAT_IMAGE_API_KEY** / **OPENAI_COMPAT_IMAGE_MODEL**: Required if using **openai_compatible** to send image requests to any OpenAI-compatible `/v1/images/*` endpoint (LiteLLM, Azure, vLLM Gateways, etc.). #### Telemetry - **DISABLE_ANONYMOUS_TRACKING**=[true/false]: Set to **true** to disable anonymous telemetry. #### Authentication (web login) Presenton uses a **single admin account** per instance. Credentials live in `app_data` (hashed; see `userConfig.json`). Pass these with `-e` or via `.env` for compose: - **AUTH_USERNAME** / **AUTH_PASSWORD** — Preseed the admin login on first boot (password at least 6 characters). Ignored if a user already exists unless **AUTH_OVERRIDE_FROM_ENV** is set. - **AUTH_OVERRIDE_FROM_ENV**=[true/false] — If **true**, replace stored credentials from the env vars on every FastAPI startup and rotate the session signing secret (invalidates existing sessions). Remove after a one-off rotation. - **RESET_AUTH**=[true/false] — If **true**, clear stored credentials on startup. Use for a **single** boot to recover access, then unset. **Examples** ```bash docker run -it --name presenton -p 5001:80 -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest ``` ```bash docker run -it --name presenton -p 5001:80 -e AUTH_USERNAME=admin -e AUTH_PASSWORD=changeme123 -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest ``` ```bash docker run -it --name presenton -p 5001:80 -e AUTH_USERNAME=admin -e AUTH_PASSWORD=changeme123 -v "${PWD}\app_data:/app_data" ghcr.io/presenton/presenton:latest ``` ```bash docker stop presenton && docker rm presenton && docker run -it --name presenton -p 5001:80 -e AUTH_USERNAME=admin -e AUTH_PASSWORD=newcred456 -e AUTH_OVERRIDE_FROM_ENV=true -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest ``` ```bash docker stop presenton && docker rm presenton && docker run -it --name presenton -p 5001:80 -e RESET_AUTH=true -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest ``` ```bash docker stop presenton && docker rm presenton && docker run -it --name presenton -p 5001:80 -e AUTH_USERNAME=admin -e AUTH_PASSWORD=changeme123 -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest ``` **Manual reset:** stop the container, edit `./app_data/userConfig.json`, delete `AUTH_USERNAME`, `AUTH_PASSWORD_HASH`, and `AUTH_SECRET_KEY`, save, and start again. Sign out from the app: **Settings → Other → Sign out**. #### MCP authentication When auth is configured (`AUTH_USERNAME` / `AUTH_PASSWORD`), the MCP endpoint at `/mcp` now requires authentication as well. 1. Log in once to get a bearer token: ```bash curl -s -X POST http://localhost:5001/api/v1/auth/login \ -H "Content-Type: application/json" \ -d '{"username":"admin","password":"changeme123"}' ``` The response includes: - `access_token` (session token) - `token_type` (`bearer`) 2. Configure your MCP client to send that token on every request: ```json { "mcpServers": { "presenton": { "url": "http://localhost:5001/mcp", "headers": { "Authorization": "Bearer " } } } } ``` Notes: - If you rotate credentials with `AUTH_OVERRIDE_FROM_ENV=true`, previously issued session tokens are invalidated. - MCP is not available in the Electron desktop app (`PRESENTON_ELECTRON=true`). Electron runs with `DISABLE_AUTH=true` by default, and the MCP server is disabled there to avoid auth conflicts. > Note: LLM and image variables above are forwarded from **`docker-compose.yml`** when set in `.env`.

**Docker Run Examples by Provider** Same variables as compose; use `-e` instead of `.env` when running `docker run` directly. - Using OpenAI

- Running Presenton with GPU Support To use GPU acceleration with Ollama models, you need to install and configure the NVIDIA Container Toolkit. This allows Docker containers to access your NVIDIA GPU. Once the NVIDIA Container Toolkit is installed and configured, you can run Presenton with GPU support by adding the `--gpus=all` flag:

docker run -it --name presenton --gpus=all -p 5001:80 -e LLM="ollama" -e OLLAMA_MODEL="llama3.2:3b" -e IMAGE_PROVIDER="pexels" -e PEXELS_API_KEY="*******" -e CAN_CHANGE_KEYS="false" -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest

- Using an OpenAI-Compatible Image Provider This routes all slide image requests through your OpenAI-compatible gateway (LiteLLM, Azure, vLLM, etc.) while keeping the text LLM configuration independent:

docker run -it --name presenton -p 5001:80 -e IMAGE_PROVIDER="openai_compatible" -e OPENAI_COMPAT_IMAGE_BASE_URL="https://proxy.example.com/v1" -e OPENAI_COMPAT_IMAGE_API_KEY="******" -e OPENAI_COMPAT_IMAGE_MODEL="gpt-image-1" -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest
