codex-subscription-router Pools Multiple ChatGPT Subscriptions Behind One Patched Desktop App via a Go Multiplexer
b-nnett/codex-subscription-router, created 2026-08-16 and already past 200 stars, builds a locally patched copy of the official ChatGPT desktop app and fans its single app-server connection out to one official Codex child process per account through a small Go multiplexer, each with an isolated Codex home. Routing is quota-aware — new chats favour weekly allowance expiring sooner, with a bounded boost for accounts holding banked resets — while threads stay sticky to one subscription so follow-ups keep conversation context and account-level caching, failing over only when depleted. The repo ships build tooling rather than OpenAI binaries and carries an explicit warning that it is unofficial and version-sensitive; whether it survives contact with the terms of service is the open question.
