OpenCodex

Universal provider proxy that lets any LLM work with Codex CLI, App, SDK, and Claude Code.

Servicefreeglobal

OpenCodex is a self-hosted universal provider proxy that lets developers use any LLM — Claude, Gemini, Grok, DeepSeek, Ollama, and more — with OpenAI's Codex CLI, App, and SDK, as well as Claude Code. It's built for developers who want model flexibility across coding-agent tools instead of being locked into each tool's default provider.
