A self-hosted uptime and infrastructure monitor with status pages and incident alerts, for teams watching servers they run themselves.
Checkmate checks whether your servers and sites are reachable and performing, records what it finds, and tells you when that changes. Frontend and backend live in the same repository, and the project has been stress-tested past a thousand active monitors without hitting a bottleneck.
The lifecycle is deliberately dull. A check runs, its result is stored with a response time, and recent results are weighed against the monitor's status change threshold. Only when that threshold is crossed does state flip, an incident open or close, and notifications go out, which is what stops one flaky response from waking anyone.
The monitor types and outputs cover most of a small fleet.
- Check types: uptime, Docker, ping, SSL, port, game server, page speed and JSON query monitoring.
- Hardware metrics: memory, disk, CPU and network, through the separate Capture agent, with per-mountpoint disk selection.
- Status pages: public pages in four themes, built from the monitors you already have.
- Notifications: email, webhooks, Discord, Slack, PagerDuty, Matrix, Rocket.Chat, Microsoft Teams, Telegram, Pushover and Twilio SMS.
- Maintenance windows: scheduled work that does not raise incidents while it runs.
Deployment is a Docker Compose file starting the application image next to MongoDB, which is required and deliberately not embedded in it. It is light enough for a Raspberry Pi 4 or 5, expects a reverse proxy in front of it for TLS, and the interface is translated into sixteen languages.
Self-hosted uptime monitoring with an API-first Go server, status pages and more than twenty alert channels, aimed at DevOps teams.
Peekaping watches your websites, APIs, containers and databases from infrastructure you run, and tells you the moment something stops answering. It was written by people who used Uptime Kuma and wanted the same idea with an API underneath it and a typed, extensible codebase behind that.
The server is Golang, the frontend React and TypeScript, and storage is your choice of SQLite, PostgreSQL or MongoDB. The quickest start is a single Docker command with a SQLite volume, and a community Terraform provider exists for teams that manage monitors as code.
Coverage spans the checks and channels a mixed stack needs.
- Network monitors: HTTP and HTTPS, TCP, ping, DNS, push webhooks, Docker containers, gRPC and SNMP.
- Data layer monitors: PostgreSQL, Microsoft SQL Server, MongoDB, Redis, MySQL and MariaDB, plus MQTT, RabbitMQ and Kafka producers.
- Alert channels: email, webhooks, Telegram, Slack, Discord, Matrix, PagerDuty, Opsgenie, ntfy, Gotify, Pushover, Twilio and a dozen more.
- Status pages: public pages and SVG status badges for readers outside the team.
- Access control: multi-factor authentication, brute-force login protection, and API keys with rights management.
- SSL checks: certificate expiration is watched alongside availability.
Every function is reachable through the REST API, which is what makes it fit CI/CD pipelines and infrastructure as code tooling. The project is in beta and under active development, so the maintainer asks you to try it outside production first. Incidents, monitor groups and an Uptime Kuma migration tool are on the roadmap.
