## 🤔 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

## 🔄 How It Works

```
┌─────────────┐
│  Your CLI   │  (Claude Code, Codex, OpenClaw, Cursor, Cline...)
│   Tool      │
└──────┬──────┘
       │ http://localhost:20128/v1
       ↓
┌─────────────────────────────────────────────┐
│           9Router (Smart Router)            │
│  • 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`

<summary><b>📖 Feature Details</b></summary>

### 🚀 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)
```

### 🎯 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!

### 🌐 Deploy Anywhere

- 💻 **Localhost** - Default, works offline
- ☁️ **VPS/Cloud** - Share across devices
- 🐳 **Docker** - One-command deployment
- 🚀 **Cloudflare Workers** - Global edge network

### 📊 Understanding 9Router Costs & Billing

**9Router Billing Reality:**

✅ **9Router software = FREE forever** (open source, never charges)  
✅ **Dashboard "costs" = Display/tracking only** (not actual bills)  
✅ **You pay providers directly** (subscriptions or API fees)  
✅ **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
• What $290 Means: Amount you SAVED by using free models!
```

**Payment Rules:**
- **Subscription providers** (Claude Code, Codex): Pay them directly via their websites
- **Cheap providers** (GLM, MiniMax): Pay them directly, 9Router just routes
- **FREE providers** (iFlow, Kiro, Qwen): Genuinely free forever, no hidden charges
- **9Router**: Never charges anything, ever

## 🎯 Use Cases

### Case 1: "I have Claude Pro subscription"

**Problem:** Quota expires unused, rate limits during heavy coding

**Solution:**
```
Combo: "maximize-claude"
  1. cc/claude-opus-4-7        (use subscription fully)
  2. glm/glm-5.1               (cheap backup when quota out)
  3. kr/claude-sonnet-4.5      (free emergency fallback)

Monthly cost: $20 (subscription) + ~$5 (backup) = $25 total
vs. $20 + hitting limits = frustration
```

### Case 2: "I want zero cost"

**Problem:** Can't afford subscriptions, need reliable AI coding

**Solution:**
```
Combo: "free-forever"
  1. kr/claude-sonnet-4.5      (Claude 4.5 free unlimited)
  2. kr/glm-5                  (GLM-5 free via Kiro)
  3. oc/<auto>                 (OpenCode Free, no auth)

Monthly cost: $0
Quality: Production-ready models + RTK saves 20-40% tokens
```

### Case 3: "I need 24/7 coding, no interruptions"

**Problem:** Deadlines, can't afford downtime

**Solution:**
```
Combo: "always-on"
  1. cc/claude-opus-4-7        (best quality)
  2. cx/gpt-5.5                (second subscription)
  3. glm/glm-5.1               (cheap, resets daily)
  4. minimax/MiniMax-M2.7      (cheapest, 5h reset)
  5. kr/claude-sonnet-4.5      (free unlimited)

Result: 5 layers of fallback = zero downtime
Monthly cost: $20-200 (subscriptions) + $10-20 (backup)
```

### Case 4: "I want FREE AI in OpenClaw"

**Problem:** Need AI assistant in messaging apps (WhatsApp, Telegram, Slack...), completely free

**Solution:**
```
Combo: "openclaw-free"
  1. kr/claude-sonnet-4.5      (Claude 4.5 free)
  2. kr/glm-5                  (GLM-5 free)
  3. kr/MiniMax-M2.5           (MiniMax free)

Monthly cost: $0
Access via: WhatsApp, Telegram, Slack, Discord, iMessage, Signal...
```

## ❓ 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`
- **Vertex AI**: $300 free credits for new Google Cloud accounts (90 days)

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.

### Environment Variables

| Variable | Default | Description |
|----------|---------|-------------|
| `JWT_SECRET` | `9router-default-secret-change-me` | JWT signing secret for dashboard auth cookie (**change in production**) |
| `INITIAL_PASSWORD` | `123456` | First login password when no saved hash exists |
| `DATA_DIR` | `~/.9router` | Main app database location (`db.json`) |
| `PORT` | framework default | Service port (`20128` in examples) |
| `HOSTNAME` | framework default | Bind host (Docker defaults to `0.0.0.0`) |
| `NODE_ENV` | runtime default | Set `production` for deploy |
| `BASE_URL` | `http://localhost:20128` | Server-side internal base URL used by cloud sync jobs |
| `CLOUD_URL` | `https://9router.com` | Server-side cloud sync endpoint base URL |
| `NEXT_PUBLIC_BASE_URL` | `http://localhost:3000` | Backward-compatible/public base URL (prefer `BASE_URL` for server runtime) |
| `NEXT_PUBLIC_CLOUD_URL` | `https://9router.com` | Backward-compatible/public cloud URL (prefer `CLOUD_URL` for server runtime) |
| `API_KEY_SECRET` | `endpoint-proxy-api-key-secret` | HMAC secret for generated API keys |

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: `${DATA_DIR}/db.json` (providers, combos, aliases, keys, settings), managed by `src/lib/localDb.js`.
- Usage history and logs: `${DATA_DIR}/usage.json` and `${DATA_DIR}/log.txt`, managed by `src/lib/usageDb.js`.
- Optional request/translator logs: `<repo>/logs/...` when `ENABLE_REQUEST_LOGS=true`.
- Both `${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** — 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**.

Huge thanks to these authors — without their work, 9Router's token-saving features wouldn't exist. ⭐ them on GitHub!
