Geoffrey Huntley open-sourced underclass, a local proxy that pools multiple ChatGPT/Codex and GitHub Copilot subscriptions behind a single OpenAI-compatible endpoint.
- Exposes /v1/responses, /v1/chat/completions and /v1/models, so any OpenAI-compatible client (e.g. opencode) works out of the box
- Features sticky sessions, a health pool, automatic quota failover and fail-fast saturation handling
- Subscriptions authenticate via OAuth device flow; a web UI is included for management
- Written in Rust, with ADR docs, tests and agent skills config in the repo
A practical tool for developers juggling several paid subscriptions who want to treat their quota as one resource pool.
