Upbar
Uptime checks in your macOS menu bar, built for SREs.
Upbar checks your HTTP endpoints every minute and alerts when one goes down. Each endpoint has p50 to p99 latency, a 24-hour chart, incidents with MTTR, a DNS/TLS/server trace, and certificate expiry. Deploy events from Coolify, CI, or curl arrive straight on the Mac. Two Swift files, no dependencies, about 20 MB of memory.
