ccNexus

Why we included this project

Anyone who runs Claude Code or Codex CLI against several upstream providers will recognize the problem ccNexus solves: an endpoint goes down, a token expires mid-session, or the provider's message format doesn't match what the client expects. The gateway runs locally on port 3000 and takes over that plumbing, failing over across configured endpoints automatically and converting between Claude, OpenAI, and Gemini formats so one client can talk to whichever backend is available. The Codex token pool is the most useful piece here, accepting bulk imports of access and refresh token pairs, rotating them, refreshing expired ones, and isolating invalid credentials while tracking per-token usage and error counts. It ships as a cross-platform desktop app and as a headless Docker service, so it works on a laptop or sits behind a reverse proxy on a server. Teams juggling several API keys or providers get one stable entry point for their coding agents instead of editing configs whenever a key changes.
