## What it is
opencodex is a lightweight local proxy (installed via npm, running on a bundled Bun runtime) that translates OpenAI Codex's Responses API and Claude Code's wire format into any LLM provider's API — Anthropic, Gemini, Grok, DeepSeek, Kimi, Ollama, OpenRouter, and 40+ others. It supports streaming, tool calls, reasoning tokens, and images in both directions, with a web dashboard, model routing, ChatGPT account pooling, and sub-agent support, all without patching the client.

## Use cases
- use Claude or Gemini models with OpenAI Codex CLI
- run Claude Code on non-Anthropic models
- route Codex App requests to DeepSeek or Ollama
- pool multiple ChatGPT accounts for Codex quota balancing
- translate OpenAI Responses API to Anthropic Messages format
- add web search and vision sidecars to routed models
- pin multiple models as Codex spawn_agent sub-agents

## When to choose
- you use Codex CLI/App/SDK or Claude Code but want models from other providers
- you want a zero-patch local proxy that handles streaming, tool calls, and reasoning tokens
- you need ChatGPT account pooling with quota-aware routing
- you want routed models to appear natively in the Codex model picker

## When to avoid
- you only use OpenAI models directly with no need for provider translation
- you need a hosted/production gateway rather than a local developer proxy
- your client is not Codex, Claude Code, Claude Desktop, or Grok Build
- you cannot run Node >= 18 or install global npm packages
