Universal provider proxy for OpenAI Codex & Claude Code — use any LLM (Claude, Gemini, Grok, DeepSeek, Ollama…) with Codex CLI, App, SDK, and Claude Code
opencodex is a local proxy that lets OpenAI Codex and other coding tools use language models from different providers through a common interface. It is for people who want to run models such as Claude, Gemini, Grok, DeepSeek, or Ollama with Codex, Claude Code, Claude Desktop, or Grok Build. The catalogue add-on supports workflows built around this proxy.
This repository also configures its own agents. See what opencodex tells them →
