opencodex

What it does

Many AI coding tools are built to talk to one company's models. opencodex is a small program on your computer that translates between them, so Codex, Claude Code, Claude Desktop and Grok Build can use other AI models.

Its makers say it supports more than 40 providers, including Gemini, DeepSeek, Kimi, Qwen and local models through Ollama. You set it up in a web dashboard on your own computer, and a beta desktop app is also available.
