+## 🤔 Why 9Router?
+
+**Stop wasting money, tokens and hitting limits:**
+
+- ❌ Subscription quota expires unused every month
+- ❌ Rate limits stop you mid-coding
+- ❌ Tool outputs (git diff, grep, ls...) burn tokens fast
+- ❌ Expensive APIs ($20-50/month per provider)
+- ❌ Manual switching between providers
+
+**9Router solves this:**
+
+- ✅ **RTK Token Saver** - Auto-compress tool_result content, save 20-40% tokens per request
+- ✅ **Maximize subscriptions** - Track quota, use every bit before reset
+- ✅ **Auto fallback** - Subscription → Cheap → Free, zero downtime
+- ✅ **Multi-account** - Round-robin between accounts per provider
+- ✅ **Universal** - Works with Claude Code, Codex, Cursor, Cline, any CLI tool

+┌─────────────┐
+│  Your CLI   │  (Claude Code, Codex, OpenClaw, Cursor, Cline...)
+│   Tool      │
+└──────┬──────┘
+       │ http://localhost:20128/v1
+       ↓
+┌─────────────────────────────────────────────┐

+│  • RTK Token Saver (cut tool_result tokens) │
+│  • Format translation (OpenAI ↔ Claude)     │
+│  • Quota tracking                           │
+│  • Auto token refresh                       │
+└──────┬──────────────────────────────────────┘
+       │
+       ├─→ [Tier 1: SUBSCRIPTION] Claude Code, Codex, GitHub Copilot
+       │   ↓ quota exhausted
+       ├─→ [Tier 2: CHEAP] GLM ($0.6/1M), MiniMax ($0.2/1M)
+       │   ↓ budget limit
+       └─→ [Tier 3: FREE] Kiro, OpenCode Free, Vertex ($300 credits)
+
+Result: Never stop coding, minimal cost + 20-40% token savings via RTK
+```
+
+---
+
+## ⚡ Quick Start
+
+**1. Install globally:**
+
+```bash
+npm install -g 9router
+9router
+```
+
+🎉 Dashboard opens at `http://localhost:20128`
+
+**2. Connect a FREE provider (no signup needed):**
+
+Dashboard → Providers → Connect **Kiro AI** (free Claude unlimited) or **OpenCode Free** (no auth) → Done!
+
+**3. Use in your CLI tool:**
+
+```
+Claude Code/Codex/OpenClaw/Cursor/Cline Settings:
+  Endpoint: http://localhost:20128/v1
+  API Key: [copy from dashboard]
+  Model: kr/claude-sonnet-4.5
+```
+
+**That's it!** Start coding with FREE AI models.
+
+**Alternative: run from source (this repository):**
+
+This repository package is private (`9router-app`), so source/Docker execution is the expected local development path.
+
+```bash
+cp .env.example .env
+npm install
+PORT=20128 NEXT_PUBLIC_BASE_URL=http://localhost:20128 npm run dev
+```
+
+Production mode:
+
+```bash
+npm run build
+PORT=20128 HOSTNAME=0.0.0.0 NEXT_PUBLIC_BASE_URL=http://localhost:20128 npm run start
+```
+
+Default URLs:
+
+- Dashboard: `http://localhost:20128/dashboard`
+- OpenAI-compatible API: `http://localhost:20128/v1`

+
+### 🚀 RTK Token Saver
+
+Tool outputs (`git diff`, `grep`, `find`, `ls`, `tree`, log dumps...) often eat 30-50% of your prompt budget. RTK detects them and applies smart, lossless compression **before** the request hits the LLM:
+
+- **Filters:** `git-diff`, `git-status`, `grep`, `find`, `ls`, `tree`, `dedup-log`, `smart-truncate`, `read-numbered`, `search-list`
+- **Auto-detect:** No config needed — RTK peeks the first 1KB of each `tool_result` and picks the right filter.
+- **Safe by design:** If a filter fails, throws, or makes output bigger, RTK silently keeps the original text. Errors never break your request.
+- **Universal:** Works across all formats (OpenAI, Claude, Gemini, Cursor, Kiro, OpenAI Responses) because it runs **before** any format translation.
+- **Default ON:** Toggle anytime in Dashboard → Endpoint settings.
+
+```
+Without RTK: 47K tokens sent to LLM
+With RTK:    28K tokens sent to LLM   (40% saved · same context · same answer)
+```
+
+### 🧠 Headroom Token Saver
+
+Headroom is optional and runs separately. 9Router calls Headroom's local `/v1/compress` endpoint, then keeps normal routing, fallback, auth, and usage tracking:
+
+```
+Client → 9Router → Headroom /v1/compress → 9Router → provider
+```
+
+Local setup:
+
+```bash
+pip install "headroom-ai[proxy]"
+headroom proxy --port 8787
+```
+
+Enable in Dashboard → Endpoint → Token Saver → Headroom. Default URL: `http://localhost:8787`.
+
+Docker examples:
+
+```bash
+# Headroom service in same Docker network
+http://headroom:8787
+
+# Headroom running on host machine
+http://host.docker.internal:8787
+```
+
+If Headroom is down or returns an error, 9Router fails open and sends the original request.
+
+### 🐴 Ponytail (Lazy Senior Dev)
+
+Ponytail injects a _"lazy senior dev"_ system prompt into every request, biasing the LLM toward minimal, YAGNI-first code — deletion over addition, stdlib over new deps, one-liners over abstractions. Adapted from [DietrichGebert/ponytail](https://github.com/DietrichGebert/ponytail).
+
+- **Lite** — Build what's asked, name the lazier alternative.
+- **Full** — YAGNI ladder enforced: stdlib → native → existing deps → one-liner → minimal code.
+- **Ultra** — YAGNI extremist: deletion first, ship the one-liner, challenge the rest of the requirement in the same response.
+
+```
+Without Ponytail: verbose code, extra abstractions, "just in case" scaffolding
+With Ponytail:    shortest working diff, no unrequested abstractions, fewer tokens
+```
+
+Never trades away: input validation, error handling that prevents data loss, security, accessibility, or anything explicitly requested. Enable in Dashboard → Endpoint → Ponytail. Stacks with Caveman (output terseness) and RTK (input compression).
+
+### 🎯 Smart 3-Tier Fallback
+
+Create combos with automatic fallback:
+
+```
+Combo: "my-coding-stack"
+  1. cc/claude-opus-4-6        (your subscription)
+  2. glm/glm-4.7               (cheap backup, $0.6/1M)
+  3. if/kimi-k2-thinking       (free fallback)
+
+→ Auto switches when quota runs out or errors occur
+```
+
+### 📊 Real-Time Quota Tracking
+
+- Token consumption per provider
+- Reset countdown (5-hour, daily, weekly)
+- Cost estimation for paid tiers
+- Monthly spending reports
+
+### 🔄 Format Translation
+
+Seamless translation between formats:
+
+- **OpenAI** ↔ **Claude** ↔ **Gemini** ↔ **Cursor** ↔ **Kiro** ↔ **Vertex** ↔ **Antigravity** ↔ **Ollama** ↔ **OpenAI Responses**
+- Your CLI tool sends OpenAI format → 9Router translates → Provider receives native format
+- Works with any tool that supports custom OpenAI endpoints
+
+### 👥 Multi-Account Support
+
+- Add multiple accounts per provider
+- Auto round-robin or priority-based routing
+- Fallback to next account when one hits quota
+
+### 🔄 Auto Token Refresh
+
+- OAuth tokens automatically refresh before expiration
+- No manual re-authentication needed
+- Seamless experience across all providers
+
+### 🎨 Custom Combos
+
+- Create unlimited model combinations
+- Mix subscription, cheap, and free tiers
+- Name your combos for easy access
+- Share combos across devices with Cloud Sync
+
+### 📝 Request Logging
+
+- Enable debug mode for full request/response logs
+- Track API calls, headers, and payloads
+- Troubleshoot integration issues
+- Export logs for analysis
+
+### 💾 Cloud Sync
+
+- Sync providers, combos, and settings across devices
+- Automatic background sync
+- Secure encrypted storage
+- Access your setup from anywhere
+
+#### Cloud Runtime Notes
+
+- Prefer server-side cloud variables in production:
+  - `BASE_URL` (internal callback URL used by sync scheduler)
+  - `CLOUD_URL` (cloud sync endpoint base)
+- `NEXT_PUBLIC_BASE_URL` and `NEXT_PUBLIC_CLOUD_URL` are still supported for compatibility/UI, but server runtime now prioritizes `BASE_URL`/`CLOUD_URL`.
+- Cloud sync requests now use timeout + fail-fast behavior to avoid UI hanging when cloud DNS/network is unavailable.
+
+### 📊 Usage Analytics
+
+- Track token usage per provider and model
+- Cost estimation and spending trends
+- Monthly reports and insights
+- Optimize your AI spending
+
+> **💡 IMPORTANT - Understanding Dashboard Costs:**
+>
+> The "cost" displayed in Usage Analytics is **for tracking and comparison purposes only**.
+> 9Router itself **never charges** you anything. You only pay providers directly (if using paid services).
+>
+> **Example:** If your dashboard shows "$290 total cost" while using iFlow models, this represents
+> what you would have paid using paid APIs directly. Your actual cost = **$0** (iFlow is free unlimited).
+>
+> Think of it as a "savings tracker" showing how much you're saving by using free models or
+> routing through 9Router!

+✅ **FREE providers stay FREE** (iFlow, Kiro, Qwen = $0 unlimited)  
+❌ **9Router never sends invoices** or charges your card
+
+**How Cost Display Works:**
+
+The dashboard shows **estimated costs** as if you were using paid APIs directly. This is **not billing** - it's a comparison tool to show your savings.
+
+**Example Scenario:**
+
+```
+Dashboard Display:
+• Total Requests: 1,662
+• Total Tokens: 47M
+• Display Cost: $290
+
+Reality Check:
+• Provider: iFlow (FREE unlimited)
+• Actual Payment: $0.00

+## ❓ Frequently Asked Questions
+
+<details>
+<summary><b>📊 Why does my dashboard show high costs?</b></summary>
+
+The dashboard tracks your token usage and displays **estimated costs** as if you were using paid APIs directly. This is **not actual billing** - it's a reference to show how much you're saving by using free models or existing subscriptions through 9Router.
+
+**Example:**
+
+- **Dashboard shows:** "$290 total cost"
+- **Reality:** You're using iFlow (FREE unlimited)
+- **Your actual cost:** **$0.00**
+- **What $290 means:** Amount you **saved** by using free models instead of paid APIs!
+
+The cost display is a "savings tracker" to help you understand your usage patterns and optimization opportunities.
+
+</details>
+
+<details>
+<summary><b>💳 Will I be charged by 9Router?</b></summary>
+
+**No.** 9Router is free, open-source software that runs on your own computer. It never charges you anything.
+
+**You only pay:**
+
+- ✅ **Subscription providers** (Claude Code $20/mo, Codex $20-200/mo) → Pay them directly on their websites
+- ✅ **Cheap providers** (GLM, MiniMax) → Pay them directly, 9Router just routes your requests
+- ❌ **9Router itself** → **Never charges anything, ever**
+
+9Router is a local proxy/router. It doesn't have your credit card, can't send invoices, and has no billing system. It's completely free software.
+
+</details>
+
+<details>
+<summary><b>🆓 Are FREE providers really unlimited?</b></summary>
+
+**Yes!** The current FREE providers (Kiro, OpenCode Free, Vertex) are genuinely free with **no hidden charges**.
+
+These are free services offered by those respective companies:
+
+- **Kiro AI**: Free unlimited Claude 4.5 + GLM-5 + MiniMax via AWS Builder ID / Google / GitHub OAuth
+- **OpenCode Free**: No-auth passthrough proxy, models auto-fetched from `opencode.ai/zen/v1/models`

+
+9Router just routes your requests to them - there's no "catch" or future billing. They're truly free services, and 9Router makes them easy to use with fallback support.
+
+**Discontinued free tiers (no longer recommended):**
+
+- ❌ **iFlow**: Was free unlimited, now changed to paid (2026)
+- ❌ **Qwen Code**: Free OAuth tier discontinued by Alibaba on 2026-04-15
+- ❌ **Gemini CLI**: Still works, but using it with non-CLI tools (Claude, Codex, Cursor...) may result in account bans — only use if you stick to Gemini CLI itself
+
+</details>
+
+<details>
+<summary><b>💰 How do I minimize my actual AI costs?</b></summary>
+
+**Free-First Strategy:**
+
+1. **Start with 100% free combo:**
+
+   ```
+   1. gc/gemini-3-flash (180K/month free from Google)
+   2. if/kimi-k2-thinking (unlimited free from iFlow)
+   3. qw/qwen3-coder-plus (unlimited free from Qwen)
+   ```
+
+   **Cost: $0/month**
+
+2. **Add cheap backup** only if you need it:
+
+   ```
+   4. glm/glm-4.7 ($0.6/1M tokens)
+   ```
+
+   **Additional cost: Only pay for what you actually use**
+
+3. **Use subscription providers last:**
+   - Only if you already have them
+   - 9Router helps maximize their value through quota tracking
+
+**Result:** Most users can operate at $0/month using only free tiers!
+
+</details>
+
+<details>
+<summary><b>📈 What if my usage suddenly spikes?</b></summary>
+
+9Router's smart fallback prevents surprise charges:
+
+**Scenario:** You're on a coding sprint and blow through your quotas
+
+**Without 9Router:**
+
+- ❌ Hit rate limit → Work stops → Frustration
+- ❌ Or: Accidentally rack up huge API bills
+
+**With 9Router:**
+
+- ✅ Subscription hits limit → Auto-fallback to cheap tier
+- ✅ Cheap tier gets expensive → Auto-fallback to free tier
+- ✅ Never stop coding → Predictable costs
+
+**You're in control:** Set spending limits per provider in dashboard, and 9Router respects them.

+
+Notes:
+
+- Lowercase proxy variables are also supported: `http_proxy`, `https_proxy`, `all_proxy`, `no_proxy`.
+- `.env` is not baked into Docker image (`.dockerignore`); inject runtime config with `--env-file` or `-e`.
+- On Windows, `APPDATA` can be used for local storage path resolution.
+- `INSTANCE_NAME` appears in older docs/env templates, but is currently not used at runtime.
+
+### Runtime Files and Storage
+
+- Main app state: `${DATA_DIR}/db/data.sqlite` (SQLite — providers, combos, aliases, keys, settings, usage history)
+- Auto backups: `${DATA_DIR}/db/backups/`
+- Optional request/translator logs: `<repo>/logs/...` when `ENABLE_REQUEST_LOGS=true`
+- Both `${DATA_DIR}` and `~/.9router` resolve to the same location in a Docker container — the symlink `/root/.9router -> /app/data` is created at build time.

+
+## 🐛 Troubleshooting
+
+**"Language model did not provide messages"**
+
+- Provider quota exhausted → Check dashboard quota tracker
+- Solution: Use combo fallback or switch to cheaper tier
+
+**Rate limiting**
+
+- Subscription quota out → Fallback to GLM/MiniMax
+- Add combo: `cc/claude-opus-4-7 → glm/glm-5.1 → kr/claude-sonnet-4.5`
+
+**OAuth token expired**
+
+- Auto-refreshed by 9Router
+- If issues persist: Dashboard → Provider → Reconnect
+
+**High costs**
+
+- Enable RTK in Dashboard → Endpoint settings (default ON, saves 20-40% tokens)
+- Check usage stats in Dashboard
+- Switch primary model to GLM/MiniMax
+- Use free tier (Kiro, OpenCode Free, Vertex) for non-critical tasks
+
+**Dashboard opens on wrong port**
+
+- Set `PORT=20128` and `NEXT_PUBLIC_BASE_URL=http://localhost:20128`
+
+**First login not working**
+
+- Check `INITIAL_PASSWORD` in `.env`
+- If unset, fallback password is `123456`
+
+**No request logs under `logs/`**
+
+- Set `ENABLE_REQUEST_LOGS=true`

+## 🙏 Acknowledgments
+
+Built on the shoulders of giants:
+
+- **[CLIProxyAPI](https://github.com/router-for-me/CLIProxyAPI)** — original Go implementation that inspired this JavaScript port.
+- **[RTK](https://github.com/rtk-ai/rtk)** ![Stars](https://img.shields.io/github/stars/rtk-ai/rtk?style=flat&color=yellow) — Rust token-saver. 9Router ports its compression pipeline to JS → **−20-40% input tokens** on every request.
+- **[Caveman](https://github.com/JuliusBrussee/caveman)** ![Stars](https://img.shields.io/github/stars/JuliusBrussee/caveman?style=flat&color=yellow) by **[@JuliusBrussee](https://github.com/JuliusBrussee)** — viral _"why use many token when few token do trick"_. 9Router adapts its prompt → **−65% output tokens**.
+- **[Ponytail](https://github.com/DietrichGebert/ponytail)** ![Stars](https://img.shields.io/github/stars/DietrichGebert/ponytail?style=flat&color=yellow) by **[@DietrichGebert](https://github.com/DietrichGebert)** — _"lazy senior dev"_ skill. 9Router injects its YAGNI-first ladder → **fewer tokens, less code, shorter diffs**.
+
+Huge thanks to these authors — without their work, 9Router's token-saving features wouldn't exist. ⭐ them on GitHub!
