9Router: The Unlimited Free AI Coding Router — 2026 Guide
9Router is an open-source LLM gateway that connects Claude Code, Codex, Cursor and more to 40+ free AI providers — with auto-fallback and up to 40% token savings. Here's everything you need to know.
Hitting rate limits on Claude Code, Codex, or Cursor is one of the most frustrating parts of AI-assisted development. 9Router solves this with a simple idea: an open-source router that connects your favorite AI coding agents to 40+ free AI providers, so you never run out of tokens again.

Instead of paying per token or juggling multiple API keys, you configure one router and let it distribute your requests across dozens of free endpoints.
Key Features
- 40+ free providers — Claude, GPT, Gemini and more, all in one place
- Auto-fallback — if one provider is down or rate-limited, traffic routes to the next automatically
- RTK mode — cuts token usage by up to 40%
- Agent support — works with Claude Code, Codex, Cursor, Cline, Copilot and Antigravity
- Web dashboard — monitor routes, API keys and provider health in real time
Why Developers Love It
The killer feature is resilience. When a free provider throttles your account, 9Router transparently falls back to another endpoint — your coding session never breaks. Combined with the RTK token compression, heavy users report dramatically longer sessions before hitting any ceiling.
