The router creates a separate patched copy of the official desktop app. It balances new chats across connected subscriptions and records which account owns each thread, with explicit behavior when that account is depleted. The repository documents compatibility checks and build requirements because patching depends on the upstream application version. Blackham’s short build account explains using Codex to implement the project.[3][5]

Codex Subscription Router
github.comA desktop companion that routes chats across connected subscriptions and tracks per-thread account ownership.
Read the compatibility and account-isolation sections before attempting the documented build. macOS development tooling, Go and Node.js are prerequisites; changes to the upstream desktop app can invalidate a previously working patch.
