relaybar
AI coding account pools and quotas, in the macOS menu bar.
01The project
A focused macOS menu-bar tool for people who run multiple AI coding accounts every day. It keeps account pools, remaining quota, and throttled states visible before a run stalls.
02The problem
AI-coding sessions can fail because quota or account-pool status stays invisible until a provider throttles a run. A compact menu-bar signal gives users that warning before work stalls.
03Key decisions
I built a native macOS menu-bar app that polls quota and account status, then keeps the signal one click away so users can switch pools before a coding run stalls.
04My contribution
- Live menu-bar readout of account pool + remaining quota across providers
- Clear signal when a pool is exhausted or throttled, so you can switch before a run stalls
- Low-distraction, always-on surface that lives in the macOS menu bar
05Design in practice
Why it exists
It comes from a daily coordination problem: people using several AI-coding accounts need to know which pool still has quota before a run stops halfway. relaybar is a native Swift app in the macOS menu bar that polls provider quota endpoints and keeps each pool's state visible.
Open-sourced under MIT, relaybar is a focused macOS tool that makes quota limits visible early enough to act.
06Outcome and current stage
Open-source MIT macOS menu-bar tool · built for daily AI-coding account monitoring
Technical details & evidence
Role · Sole author
- Native Swift menu-bar app; polls provider quota endpoints on an interval
- Built from the seat of a daily Codex / Claude Code / Antigravity user — the real pain is account-pool rotation, quota exhaustion, and multi-provider context, not model quality
- Open source under MIT; a small, focused macOS tool that turns daily account-limit problems into an early warning signal
