Checkmate is a free, open-source (AGPL-3.0) monitoring platform from BlueWave Labs that watches website uptime, server hardware, and Docker hosts, then publishes public status pages when something goes wrong. It serves small teams, homelabs, and DevOps shops that want uptime checks, infrastructure metrics, incidents, and notifications in one self-hosted tool instead of several subscriptions.[1][2]
Quick verdict
Small teams that want self-hosted uptime monitoring plus public status pages in one free tool benefit most from Checkmate. Its ten monitor types, Docker and infrastructure checks, incident tracking, and twelve notification channels cover the core uptime workflow without a subscription. The constraint is operations: deployment needs Docker with MongoDB, and no managed hosting or confirmed SSO was observed, so teams without server capacity should choose something else. If you can self-host, choose Checkmate for the broader monitor and status-page bundle; if you need the lightest setup or a managed service, start with Uptime Kuma or a hosted alternative.[1][2]
Key features
Ten monitor types Monitor HTTP(s), Ping, TCP, gRPC, WebSocket, DNS, PageSpeed, Infrastructure, Docker, and Game Servers side by side in one dashboard.[1][2]
Uptime and response-time history Track uptime percentages with response-time charts and date-range filtering per monitor, so slow periods stay visible rather than anecdotal.[1][2]
PageSpeed and Lighthouse checks Run PageSpeed performance checks backed by Lighthouse and keep historical charts of page-speed changes.[1][2]
Infrastructure via Capture agent Watch CPU, memory, disk, and host health through the Capture agent, with alert thresholds on the metrics that matter.[1][2]
Docker container monitoring Track Docker container CPU, memory, disk, and uptime next to website checks in the same dashboard.[1]
Public status pages Publish public status pages with themes, custom domains, and subscriber updates so users learn about outages first.[1][2]
Incidents plus maintenance windows Record acknowledged and resolved incident states linked to monitors, and schedule maintenance windows that pause alerts during planned work.[1][2]
Twelve notification channels Send alerts through twelve channels including Slack, Discord, Teams, PagerDuty, Opsgenie, email, and webhooks, routed per monitor, with TLS certificate-expiry tracking and pause/schedule/maintenance controls.[1][2]
Who will love it
Uptime plus status pages free Small teams that want uptime monitoring plus status pages in one free tool covering the whole outage-communication loop at zero licence cost.[1][2]
Container shops Docker and Kubernetes shops that want container and host metrics next to website checks in one dashboard.[1]
Homelab subscription replacement Homelabs replacing proprietary uptime subscriptions, where AGPL-3.0 self-hosting removes the monthly fee for people comfortable running Docker and MongoDB.[1][2]
Who should avoid it
Self-hosting only Self-hosting is the only route observed: a Docker deployment with MongoDB to install, update, and back up, with no managed offering stated.[1][2]
SSO unconfirmed Single sign-on availability was not established on the pages checked, so larger teams should verify current docs before adopting on that basis.[1][2]
No user-report sample No original Reddit or G2 user report was located within the research budget, so fit claims rest on official documentation rather than inspected user experience.[1]
Deployment and fit notes
Docker, Helm, or source install Deploy from a single Docker Compose setup with MongoDB, with a Helm chart and source install as alternates and multi-arch images.[1][2]
Per-monitor routing Route notifications per monitor across the twelve supported channels, and pause alerts with maintenance windows during planned work.[1][2]
Status pages for outage comms Publish status pages with custom domains, themes, and subscriber updates for public outage communication.[1]
Questions worth asking
What is the best Checkmate alternative for non-technical users?
A hosted uptime and status-page service is the safer conditional pick for non-technical users, because Checkmate needs Docker plus MongoDB self-hosting at moderate difficulty. Among self-hosted peers, Uptime Kuma is the catalogue-positioned incumbent Checkmate is compared against. This stays conditional because no head-to-head testing was done in this pass.[1][2]
Is Checkmate really no-code?
How much does Checkmate cost per month?
Nothing for the licence: Checkmate is AGPL-3.0 with a free self-hosted deployment as the whole product, and no paid tier or price was stated on any page checked on October 9, 2026. A free licence does not imply free hosting: it runs on your own servers, and no total-infrastructure estimate is given here.[1][2]
Can you self-host Checkmate?
Yes: deployment is a single Docker Compose setup with MongoDB, with a Helm chart and source install as alternates and multi-arch images, on Docker, Kubernetes, Linux, and Windows per the catalogue record. A public repository alone would not prove this, but the docs describe the deployment routes directly. No installation guide is included in this article.[1][2]
