What it does

An OpenAI-compatible router over 7 free-tier providers and 30+ models. It picks by capability tier and quota, fails over when one runs out, and runs as an MCP server for Claude Code. A browser version covers the 5 providers that accept calls from a web page.

Highlights

• Three tiers: reasoning, general, fast.
• Quota tracking, cooldowns and automatic model discovery.
• In the browser: bring your own keys, then chat or compare models side by side.
