Self-hosted and Docker-friendly. - **The Catch vs Instatus**: 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. ### Cachet - **Fork Page**: [Cachet Profile](https://caniforkit.com/fork/cachet) - **Head-to-Head Comparison**: [Instatus vs Cachet](https://caniforkit.com/vs/instatus-vs-cachet) - **Official Website**: https://cachethq.io - **Source Code Repository**: https://github.com/cachethq/cachet - **License**: Open Source - **Runs On**: Self-host - **GitHub Stars**: 15.3k - **Maintenance Activity**: nov 2026 - **Supported Platforms**: web, self-hosted, docker to self-host - **Summary**: Open-source status page platform that helps organizations communicate system status and incidents effectively with customizable components and metrics tracking - **The Catch vs Instatus**: Requires self-hosting setup, updates, and server maintenance compared to managed Instatus. - **Installation**: Clone https://github.com/cachethq/cachet or deploy with Docker Compose - **Setup**: Deploy via Docker or binary release from GitHub and configure environment variables. - **Data Storage**: All application data and configuration live on your own server or local database. ### Gatus - **Fork Page**: [Gatus Profile](https://caniforkit.com/fork/gatus) - **Head-to-Head Comparison**: [Instatus vs Gatus](https://caniforkit.com/vs/instatus-vs-gatus) - **Official Website**: https://gatus.io - **Source Code Repository**: https://github.com/twin/gatus - **License**: Apache-2.0 - **Runs On**: Self-host - **GitHub Stars**: 12.5k - **Maintenance Activity**: nov 2026 - **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 Instatus**: 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. ### OpenStatus - **Fork Page**: [OpenStatus Profile](https://caniforkit.com/fork/openstatus) - **Head-to-Head Comparison**: [Instatus vs OpenStatus](https://caniforkit.com/vs/instatus-vs-openstatus) - **Official Website**: https://openstatus.dev/ - **Source Code Repository**: https://github.com/openstatushq/openstatus - **License**: Open Source - **Runs On**: Self-host - **GitHub Stars**: 9.2k - **Maintenance Activity**: nov 2026 - **Supported Platforms**: web, self-hosted, docker to self-host - **Summary**: Open-source status page and uptime monitor that tracks endpoints from 28 global regions, communicates incidents, and helps satisfy SOC 2 audit requirements. - **The Catch vs Instatus**: Requires self-hosting setup, updates, and server maintenance compared to managed Instatus. - **Installation**: Clone https://github.com/openstatushq/openstatus or deploy with Docker Compose - **Setup**: Deploy via Docker or binary release from GitHub and configure environment variables. - **Data Storage**: All application data and configuration live on your own server or local database. ### OneUptime - **Fork Page**: [OneUptime Profile](https://caniforkit.com/fork/oneuptime) - **Head-to-Head Comparison**: [Instatus vs OneUptime](https://caniforkit.com/vs/instatus-vs-oneuptime) - **Official Website**: https://oneuptime.com - **Source Code Repository**: https://github.com/OneUptime/oneuptime - **License**: Apache-2.0 - **Runs On**: Self-host - **GitHub Stars**: 7.8k - **Maintenance Activity**: nov 2026 - **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 Instatus**: 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. ### Kener - **Fork Page**: [Kener Profile](https://caniforkit.com/fork/kener) - **Head-to-Head Comparison**: [Instatus vs Kener](https://caniforkit.com/vs/instatus-vs-kener) - **Official Website**: https://kener.ing/ - **Source Code Repository**: https://github.com/rajnandan1/kener - **License**: Open Source - **Runs On**: Self-host - **GitHub Stars**: 5.2k - **Maintenance Activity**: nov 2026 - **Supported Platforms**: web, self-hosted, docker to self-host - **Summary**: Free, open-source status page and uptime monitor with Docker deployment.
