9Router - Free AI Router

Never stop coding. Auto-route to FREE & cheap AI models with smart fallback.

Free AI Provider for OpenClaw.

🚀 Quick Start • 💡 Features • 📖 Setup • 🌐 Website

🤔 Why 9Router?

Stop wasting money and hitting limits:

• ❌ Subscription quota expires unused every month
• ❌ Rate limits stop you mid-coding
• ❌ Expensive APIs ($20-50/month per provider)
• ❌ Manual switching between providers

9Router solves this:

• ✅ 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, Gemini CLI, Cursor, Cline, any CLI tool

⚡ Quick Start

1. Install globally:

npm install -g 9router
9router

🎉 Dashboard opens at http://localhost:20128

2. Connect a FREE provider (no signup needed):

Dashboard → Providers → Connect Claude Code or Antigravity → OAuth login → Done!

3. Use in your CLI tool:

Claude Code/Codex/Gemini CLI/OpenClaw/Cursor/Cline Settings:
  Endpoint: http://localhost:20128/v1
  API Key: [copy from dashboard]
  Model: if/kimi-k2-thinking

That's it! Start coding with FREE AI models.

Alternative: run from source (this repository):

📖 Feature Details

🎯 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 ↔ 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

🌐 Deploy Anywhere

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

🔧 CLI Integration

Cursor IDE

Settings → Models → Advanced:
  OpenAI API Base URL: http://localhost:20128/v1
  OpenAI API Key: [from 9router dashboard]
  Model: cc/claude-opus-4-6

Or use combo: premium-coding

Claude Code

Edit ~/.claude/config.json:

{
  "anthropic_api_base": "http://localhost:20128/v1",
  "anthropic_api_key": "your-9router-api-key"
}

Codex CLI

export OPENAI_BASE_URL="http://localhost:20128"
export OPENAI_API_KEY="your-9router-api-key"

codex "your prompt"

OpenClaw

Option 1 — Dashboard (recommended):

Dashboard → CLI Tools → OpenClaw → Select Model → Apply

Option 2 — Manual: Edit ~/.openclaw/openclaw.json:

{
  "agents": {
    "defaults": {
      "model": {
        "primary": "9router/if/glm-4.7"
      }
    }
  },
  "models": {
    "providers": {
      "9router": {
        "baseUrl": "http://127.0.0.1:20128/v1",
        "apiKey": "sk_9router",
        "api": "openai-completions",
        "models": [
          {
            "id": "if/glm-4.7",
            "name": "glm-4.7"
          }
        ]
      }
    }
  }
}

Note: OpenClaw only works with local 9Router. Use 127.0.0.1 instead of localhost to avoid IPv6 resolution issues.

🐛 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-4-6 → glm/glm-4.7 → if/kimi-k2-thinking

OAuth token expired

• Auto-refreshed by 9Router
• If issues persist: Dashboard → Provider → Reconnect

High costs

• Check usage stats in Dashboard
• Switch primary model to GLM/MiniMax
• Use free tier (Gemini CLI, iFlow) for non-critical tasks

Dashboard opens on wrong port

• Set PORT=20128 and NEXT_PUBLIC_BASE_URL=http://localhost:20128

Cloud sync errors

• Verify BASE_URL points to your running instance (example: http://localhost:20128)
• Verify CLOUD_URL points to your expected cloud endpoint (example: https://9router.com)
• Keep NEXT_PUBLIC_* values aligned with server-side values when possible.

Cloud endpoint stream=false returns 500 (Unexpected token 'd'...)

• Symptom usually appears on public cloud endpoint (https://9router.com/v1) for non-streaming calls.
• Root cause: upstream returns SSE payload (data: ...) while client expects JSON.
• Workaround: use stream=true for cloud direct calls.
• Local 9Router runtime includes SSE→JSON fallback for non-streaming calls when upstream returns text/event-stream.

Cloud says connected, but request still fails with Invalid API key

• Create a fresh key from local dashboard (/api/keys) and run cloud sync (Enable Cloud then Sync Now).
• Old/non-synced keys can still return 401 on cloud even if local endpoint works.

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

📝 API Reference

Chat Completions

POST http://localhost:20128/v1/chat/completions
Authorization: Bearer your-api-key
Content-Type: application/json

{
  "model": "cc/claude-opus-4-6",
  "messages": [
    {"role": "user", "content": "Write a function to..."}
  ],
  "stream": true
}

List Models

GET http://localhost:20128/v1/models
Authorization: Bearer your-api-key

→ Returns all models + combos in OpenAI format

Compatibility Endpoints

• POST /v1/chat/completions
• POST /v1/messages
• POST /v1/responses
• GET /v1/models
• POST /v1/messages/count_tokens
• GET /v1beta/models
• POST /v1beta/models/{...path} (Gemini-style generateContent)
• POST /v1/api/chat (Ollama-style transform path)

Cloud Validation Scripts

Added test scripts under tester/security/:

• tester/security/test-docker-hardening.sh
  • Builds Docker image and validates hardening checks (/api/cloud/auth auth guard, REQUIRE_API_KEY, secure auth cookie behavior).
• tester/security/test-cloud-openai-compatible.sh
  • Sends a direct OpenAI-compatible request to cloud endpoint (https://9router.com/v1/chat/completions) with provided model/key.
• tester/security/test-cloud-sync-and-call.sh
  • End-to-end flow: create local key -> enable/sync cloud -> call cloud endpoint with retry.
  • Includes fallback check with stream=true to distinguish auth errors from non-streaming parse issues.

Security note for cloud test scripts:

• Never hardcode real API keys in scripts/commits.
• Provide keys only via environment variables:
  • API_KEY, CLOUD_API_KEY, or OPENAI_API_KEY (supported by test-cloud-openai-compatible.sh)
• Example:

OPENAI_API_KEY="your-cloud-key" bash tester/security/test-cloud-openai-compatible.sh

Expected behavior from recent validation:

• Local runtime (http://127.0.0.1:20128/v1/chat/completions): works with stream=false and stream=true.
• Docker runtime (same API path exposed by container): hardening checks pass, cloud auth guard works, strict API key mode works when enabled.
• Public cloud endpoint (https://9router.com/v1/chat/completions):
  • stream=true: expected to succeed (SSE chunks returned).
  • stream=false: may fail with 500 + parse error (Unexpected token 'd') when upstream returns SSE content to a non-streaming client path.

Dashboard and Management API

• Auth/settings: /api/auth/login, /api/auth/logout, /api/settings, /api/settings/require-login
• Provider management: /api/providers, /api/providers/[id], /api/providers/[id]/test, /api/providers/[id]/models, /api/providers/validate, /api/provider-nodes*
• OAuth flows: /api/oauth/[provider]/[action] (+ provider-specific imports like Cursor/Kiro)
• Routing config: /api/models/alias, /api/combos*, /api/keys*, /api/pricing
• Usage/logs: /api/usage/history, /api/usage/logs, /api/usage/request-logs, /api/usage/[connectionId]
• Cloud sync: /api/sync/cloud, /api/sync/initialize, /api/cloud/*
• CLI helpers: /api/cli-tools/claude-settings, /api/cli-tools/codex-settings, /api/cli-tools/droid-settings, /api/cli-tools/openclaw-settings

Authentication Behavior

• Dashboard routes (/dashboard/*) use auth_token cookie protection.
• Login uses saved password hash when present; otherwise it falls back to INITIAL_PASSWORD.
• requireLogin can be toggled via /api/settings/require-login.

Request Processing (High Level)

1. Client sends request to /v1/*.
2. Route handler calls handleChat (src/sse/handlers/chat.js).
3. Model is resolved (direct provider/model or alias/combo resolution).
4. Credentials are selected from local DB with account availability filtering.
5. handleChatCore (open-sse/handlers/chatCore.js) detects format and translates request.
6. Provider executor sends upstream request.
7. Stream is translated back to client format when needed.
8. Usage/logging is recorded (src/lib/usageDb.js).
9. Fallback applies on provider/account/model errors according to combo rules.
