Claudodex

Claude Code, routed through your OpenAI Codex subscription.

Claudodex is a focused launcher and compatibility proxy for running the real `claude` binary against OpenAI Codex subscription models. It is not a multi-provider proxy, not a Codex CLI wrapper, and not a replacement terminal UI. You still use Claude Code. Claudodex swaps the model backend.

you -> claudodex -> installed claude -> local Anthropic-compatible proxy -> Codex

Why Claudodex?

There are already useful projects in this space, including Claudish, ccproxy-api, claude-code-proxy variants, and Codex proxy experiments. Many of them try to support a long list of providers, models, transports, and runtime styles. That flexibility is valuable, but it can also make the Claude Code plus Codex subscription path harder to install, harder to reason about, or easier to miss in small compatibility details.

Claudodex deliberately takes the opposite shape: one launcher, one target use case, and as little setup as possible. The goal is that a person with a Codex subscription and an installed `claude` binary can log in once, run `claudodex`, and get a Claude Code experience whose backend is Codex.

Why not call it `claudex`? Because that name is already used in multiple places. `Claudodex` is clunkier, but it is specific and searchable.

What It Does

• Runs your installed claude binary with normal Claude Code flags.
• Authenticates to OpenAI through claudodex clx:auth-login.
• Maps Claude model families to Codex models:
  • Opus -> gpt-5.6-sol
  • Sonnet -
