Summary

CLIProxyAPI (34.7K★, MIT, Go) is a unified proxy for AI coding CLIs . It wraps Gemini CLI, Claude Code, OpenAI Codex, Grok Build, and Antigravity behind a single API endpoint. Use OAuth to log in with your subscription accounts — no API keys needed. Multi-account rotation breaks through single-account quota limits.
