About 9Router
9Router is a free, open-source local proxy that connects AI coding tools to 40+ AI providers and 100+ models with intelligent 3-tier fallback routing. It automatically switches between subscription, cheap, and free providers so you never hit a rate limit mid-coding session. Installed via npm and running locally on port 20128, it exposes an OpenAI-compatible API endpoint that any CLI tool can point to. The dashboard provides real-time quota tracking, usage analytics, and combo management across all connected providers.
- Smart 3-Tier Fallback — Auto-routes requests through Subscription → Cheap → Free tiers; configure combos like
cc/claude-opus-4-6 → glm/glm-4.7 → if/kimi-k2-thinkingto ensure zero downtime. - Real-Time Quota Tracking — Monitors token consumption and reset countdowns (5-hour, daily, weekly) per provider so you maximize every subscription.
- Format Translation — Seamlessly translates between OpenAI, Claude, and Gemini API formats so any CLI tool works with any provider without reconfiguration.
- Multi-Account Round-Robin — Add multiple accounts per provider for load balancing and automatic failover when one account hits its quota.
- Auto Token Refresh — OAuth tokens for Claude Code, Codex, Gemini CLI, and other OAuth providers refresh automatically with no manual re-authentication.
- Custom Combos — Create and name unlimited model combinations mixing subscription, cheap, and free tiers; sync them across devices via Cloud Sync.
- 40+ Provider Support — Connects to OpenRouter, OpenAI, Anthropic, Gemini, DeepSeek, Groq, xAI, Mistral, Together AI, Fireworks, Cerebras, Cohere, NVIDIA, SiliconFlow, and 20+ more via API key.
- Free Provider Integration — Built-in support for iFlow (8 models, unlimited), Qwen (3 models, unlimited), Kiro (Claude, unlimited), and Gemini CLI (180K/month free).
- Usage Analytics — Tracks tokens, estimated costs, and spending trends over time; displays a "savings tracker" showing how much you save using free models.
- Flexible Deployment — Run on localhost, VPS, Docker, or Cloudflare Workers; configure via environment variables with full Docker and PM2 support.
- Request Logging — Enable debug mode (
ENABLE_REQUEST_LOGS=true) for full request/response logs to troubleshoot integrations. - Universal CLI Compatibility — Works with Claude Code, Cursor, Codex, OpenCode, Cline, Continue, Roo, Copilot, Kilo Code, OpenClaw, Droid, and any tool supporting custom OpenAI endpoints.
