- **Official Website**: https://uptime.kuma.pet/
- **Source Code Repository**: https://github.com/louislam/uptime-kuma
- **License**: MIT
- **Runs On**: Self-host
- **GitHub Stars**: 93.3k

- **Supported Platforms**: web, self-hosted, docker to self-host
- **Summary**: Monitors websites, APIs, and services with real-time alerts, a status page, and support for dozens of notification channels. Self-hosted and Docker-friendly.
- **The Catch vs UptimeRobot**: It is excellent for checks from your own server, but has no built-in worldwide probe fleet or polished synthetic transaction recorder.
- **Installation**: Docker Compose with a persistent `/app/data` volume, or a manual Node.js plus PM2 install
- **Setup**: It still needs an always-on host, Docker volume discipline, and outbound notification credentials; network filesystems are explicitly unsupported for the data directory.
- **Data Storage**: Monitor configuration, users, status pages, certificates, and history live in the application database under the mounted `/app/data` directory.

### Checkmate

### Gatus

- **Supported Platforms**: web, self-hosted, docker to self-host
- **Summary**: A highly customizable monitoring solution that provides automated status pages, extensive alerting options, and detailed testing capabilities for your services and infrastructure
- **The Catch vs UptimeRobot**: It is configuration-driven and normally probes from one place, so Pingdom's global probe network and recorder-style transaction checks are the major losses.
- **Installation**: Run one binary or Docker container and supply a YAML configuration; Helm is available
- **Setup**: The first hurdle is writing YAML for endpoints, conditions, alerts, and secrets; without configuring a database, history disappears on restart.
- **Data Storage**: Monitor definitions live in YAML; results are in memory by default or persist in SQLite or PostgreSQL when storage is configured.

- **Supported Platforms**: web, self-hosted, self-host, real ops
- **Summary**: All-in-one solution for uptime monitoring, incident management, and status pages to keep your services running smoothly
- **The Catch vs UptimeRobot**: It covers many adjacent jobs, but its self-hosted stack is far heavier to run and its integration depth and polish trail Datadog's mature managed platform.
- **Installation**: Hosted signup, or the release-branch Docker Compose stack; Helm is the production path
- **Setup**: The recommended self-hosted footprint is large and production requires secrets, TLS, backups, database care, and frequent upgrades rather than a single lightweight monitor.
- **Data Storage**: Self-hosted telemetry is stored in ClickHouse, application state and configuration in PostgreSQL, and cache, queues, and sessions in Redis.
