opencodex: Universal Proxy for OpenAI Codex, Claude Code, and Grok Build

Repositorylidge-jun/opencodexTool

opencodex is a local proxy written in TypeScript that connects tools like OpenAI Codex, Claude Code, Claude Desktop, and Grok Build to arbitrary LLM providers. It translates Codex's Responses API—including streaming, tool calls, reasoning tokens, and images—into formats expected by providers such as DeepSeek, Gemini, Grok, or Ollama.

Key points

  1. Universal local proxy supporting OpenAI Codex (CLI, App, SDK), Claude Code, Claude Desktop, and Grok Build.
  2. Enables routing to alternative LLM providers such as Claude, Gemini, Grok, DeepSeek, and Ollama.
  3. Bidirectionally translates API calls while handling streaming, tool calls, reasoning tokens, and image inputs.
  4. Supports multi-model subagent workflows, such as chaining Claude Opus 4.8 with GPT-5.6 Sol or Kimi K3.
  5. Installed globally via npm as @bitkyc08/opencodex and started with the 'ocx start' command.

Why it matters

Coding agent interfaces are typically locked to their native model providers. opencodex decouples the client application from the backend LLM, enabling developers to retain their preferred CLI workflows while using open-source, local, or competing hosted models.

Analysis

opencodex targets developers wanting model autonomy within tools like Claude Code and the Codex ecosystem. Built on TypeScript and Node.js, it functions as a lightweight local adapter that intercepts and translates protocol requests. Indicators of adoption and maturity include nearly 14,000 GitHub stars, over 1,000 forks, an MIT license, multi-language documentation, and packaged npm releases.
