Score: 5.8/10 (Innovation: 4, Technical: 5, Documentation: 8, Utility: 6)

Overwatch is a self-hosted, single-binary uptime monitoring and alerting system written in Go. It's interesting because it combines a CLI client with a server using Ed25519 keypairs for secure management and supports check-in webhooks for monitoring scheduled jobs, offering a modern, developer-focused alternative to tools like Uptime Kuma.

Target audience: devops, backend devs

Repository: https://github.com/processfoundry/overwatch · Go · MIT
