EmberBar is a native macOS menu bar app that tracks your Claude AI usage in real time. No more keeping a browser tab open on the usage page. A live gauge shows your burn rate and estimated time until the limit. Peak hour detection warns you when Claude counts usage 2x so you can plan around it. Get notified at 75% and 90% usage or when your burn rate spikes. Track session and weekly windows in one glance. Free, open source, privacy-first.
