CLIProxyAPI

CLIProxyAPI turns coding-agent subscriptions you already pay for (ChatGPT Codex, Claude Code, Antigravity, Grok Build, Devin, Kimi, Meta's Muse Code) into an OpenAI-, Gemini- and Claude-compatible API you can point other tools at. Log in once per account and it serves those quotas as an endpoint, with round-robin load balancing across multiple accounts. MIT licensed, a Go binary or Docker.

Setup is a single binary or docker compose, a config file, and OAuth logins per provider. It stores those tokens on the proxy host and exposes a management API, so lock it down if it ever leaves localhost. Releases ship almost daily, and Gemini CLI support moved into a separate plugin.

There's no paid tier; the cost is the subscriptions you proxy, and the risk is those accounts. Anthropic's terms say Claude plan credentials can't be routed through third-party apps, and Google's Antigravity terms call third-party access grounds for suspension. Google already ran a ban wave in February 2026 that also locked people out of Gemini CLI. Use the official APIs for anything in production.

The catch: this exists to stretch consumer plans past their intended use, and the README's sponsor wall now advertises residential proxies with one IP per account for multi-account operations. That's account-ban territory, and you're the one holding the account.
