Independent reviews from people who run Checkmate in production.
“At Magic Pages we use Checkmate to automatically monitor every customer website on our Ghost hosting platform. The API made it easy to integrate monitor lifecycle management directly into our provisioning flow, and our customers now see real-time uptime and response time data right in their dashboard. Checkmate has been rock solid for monitoring 1,100+ sites.”
Monitor everythingfrom one dashboard.
An endpoint can return 200 while the cert expires, the disk fills and a container crash-loops. A green uptime dot hides all of that, so Checkmate gives each layer its own check.
Keep everythingunder one roof.
Uptime, pagespeed, servers, containers and alerts behind a single login. Outages love the gaps between tools, so we didn't leave any.

A beautiful dashboardfor all your monitoring needs.
These are the views you'll spend the most time in. Each one loads fast, works from the keyboard and shows you what changed without making you dig for it.
Know the moment something breaks.
Track per-endpoint uptime, incident counts and response time history. Charts span a day, a week or a month, so patterns show up before they become outages.
- Real-time uptime percentage and incident tracking
- Response time charts with day, week and month views
- SSL certificate expiry monitoring
Track Lighthouse scores over time.
Checkmate scores performance, accessibility, SEO and best practices, plus Core Web Vitals. Every run is recorded, so regressions don't ship silently.
- Lighthouse performance, accessibility and SEO scores
- Core Web Vitals: LCP, FCP, CLS and more
- Score history to track improvements over time
See server health down to the core.
The Capture agent reports CPU, memory, disk and network from every box. Live gauges show what is happening now; history helps you plan capacity.
- CPU usage, temperature and core frequency
- Memory and disk usage with visual gauges
- Historical charts for capacity planning
Watch every container with one monitor.
Point Checkmate at a Docker host and it watches everything running on it: state, health, CPU, memory and restarts per container. When one goes unhealthy, you get an alert.
- One monitor covers the host and all its containers
- Local socket, remote daemon over TLS, or Capture
- Optional log collection per container
Publish a status page users trust.
Publish a public dashboard with per-service uptime bars and your own branding. Share one URL with customers, on-call and stakeholders.
- Public-facing status dashboard with custom branding
- Per-service uptime bars with historical data
- Shareable link for customers and stakeholders
Keep every outage on the record.
Checkmate opens an incident on the first failed check, tracks how long it lasts and keeps the timeline after recovery. The history is your SLA math and your postmortem notes in one place.
- Incidents created automatically from failed checks
- Timelines with start, duration and resolution
- Filter by monitor, date range or status
Plan downtime without the noise.
Schedule one-off or recurring windows and Checkmate holds the alerts while you work. Checks keep running and get recorded; nobody gets paged for the reboot you planned.
- One-off and recurring schedules
- Alerts suppressed, checks still recorded
- Windows scoped to the monitors you pick

AGPL-3.0
Source is yours to read, fork and audit. Data never leaves your perimeter.
Built in the openfor everyone.
AGPL-3.0, no vendor lock-in, no paywalled features. Read the code, file an issue or send a PR: 170-plus contributors have done exactly that. Checkmate has run in homelabs and prod racks since 2024.
Frequently askedquestions.
A Linux box (or any Docker host) with about 1 GB of RAM and a few GB of disk. Checkmate ships as a small set of containers: pull the compose file, run it, done.
AGPL-3.0. You can run it for free, fork it and modify it. If you expose a modified version as a network service, you need to share your changes under the same license.
Your monitoring data doesn't: metrics, logs, incidents and user accounts all live in the database you point Checkmate at. The server sends one anonymous daily heartbeat (version, platform and monitor counts, never URLs, names or addresses) and TELEMETRY_ENABLED=false turns it off.
A ping tells you the server answered. It can't tell you the cert is valid next week, DNS still points where it should, the disk isn't filling or a container isn't restart-looping. That's why there are 10 monitor types instead of one.
Commercial tools meter by host or monitor. Checkmate doesn't. You give up the managed cloud and some polish; you get unlimited monitors, your own data and a smaller bill.
There's no one-click import, but most existing monitors map cleanly: HTTP, ping, TCP, Docker, status pages. For bulk setup the API accepts JSON, so a short script usually does it.
Discord is the fastest path; maintainers and contributors hang out there. GitHub issues work for bugs and feature requests. There is no paid support tier.
Stop worryingabout downtime.
A single compose file, a few minutes and the next incident reaches you first, not your users. Free forever, self-hosted.
