wtf is grokbuild-proxy?

grokbuild-proxy is a self hosted proxy server that lets someone use their own Grok Build account with tools built for Claude Code and other clients that expect Anthropic or OpenAI style APIs. It translates requests between these different API formats so that a coding tool built to talk to Claude can instead send its requests through to Grok, and get a response back in the format it expects. The project supports streaming responses, function calling by tools, structured output formats, and Grok's own web search feature mapped into the Anthropic style API. It also handles account related tasks like OAuth based browser login, managing a pool of multiple accounts with automatic failover if one hits a rate limit or cooldown, and storing credentials locally in JSON files with file locking and backups. Setup can be done with a one line install script for Linux, macOS, or Windows, by building from source with Go, or by running it through Docker Compose. Once running, it exposes a local web based admin interface where you log in with your Grok account, import credentials, manage the account pool, and create or revoke API keys for client applications. To use it with Claude Code, you point the CLI's base URL and auth token environment variables at the local proxy instead of Anthropic's servers directly. The README is explicit that this is an unofficial, community maintained project for technical learning and protocol interoperability research, with no affiliation to xAI, Grok, Anthropic, or OpenAI. It warns that using it may violate the terms of service of the underlying account and that all risk falls on the user, and instructs that only accounts you legally own and are permitted to automate should be used with it. The project is released under the MIT license.
