opencodex
VerifiedUniversal provider proxy for OpenAI Codex & Claude Code — use any LLM (Claude, Gemini, Grok, DeepSeek, Ollama…) with Codex CLI, App, SDK, and Claude...
Tool overview
Overview
opencodex is a lightweight local proxy that translates Codex's Responses API into the protocol used by a chosen provider, supporting streaming, tool calls, reasoning tokens, and images in both directions. It allows Codex, Claude Code, Claude Desktop, and Grok Build to run with Claude, Gemini, Grok, GLM, DeepSeek, Kimi, Qwen, Ollama, or other LLMs. The project provides a CLI and a web dashboard on localhost:10100 for configuration. Users can add providers from 40+ built-ins or any OpenAI-compatible endpoint, pick models, and manage accounts. opencodex can also manage a ChatGPT account pool for Codex auth, including adding multiple ChatGPT / Codex accounts and refreshing their 5h / weekly / 30d quota in the dashboard. Under quota routing, new sessions can use the lowest-usage healthy account, while round-robin and fill-first use their own policies. Existing Codex threads normally retain affinity to the account that started them. Additional
features
include combos that expose one virtual model id with failover or weighted round-robin across providers, sub-agents on any model, OAuth for xAI, Anthropic, and Kimi, and web search and vision sidecars for non-OpenAI models. The dashboard shows providers, OAuth status, model selection, and a live request log with cache token counts. A desktop app (beta) provides the same proxy and dashboard in a native window, and supported platforms include macOS, Linux, and Windows.
