About these scores

OSS scale score is an unbounded metric that log-compresses and weights Stars, Watchers, Forks, and Contributors. Discovery score is the current OSS scale score minus the score at discovery. Update pace is commits in the last 30 days, growth momentum is the OSS scale score difference within the recent observation window, and OSS health is a 0–100 rating based on available recency, Community Health, and release data.

Overview

Checkmate is a self-hosted monitoring platform for uptime, response times, and incidents, with an optional Capture agent for CPU, RAM, disk, temperature, and other server metrics.

Features and best fit

Based on official documentation; not hands-on tested · Content checked:

Continuously monitor uptime, response time, and incidents

Periodic checks track availability, latency, downtime, and incidents across websites and services.

Sources: [2][3]

Add server hardware metrics through the Capture agent

A separate agent can report CPU, RAM, disk, temperature, and related infrastructure metrics.

Sources: [2][4]

For consolidating UptimeRobot-style checks and server metrics on owned infrastructure

It fits teams that want endpoint monitoring and infrastructure visibility in one self-hosted interface.

Check image/version differences between deployment methods

The reference Compose uses the current all-in-one application plus MongoDB, while the README says the Helm chart still targets legacy images.

Supplemental curator note

Checkmate ships frontend and backend together, while deeper hardware metrics come from the separate Capture agent. The current reference Docker Compose runs the application plus MongoDB. Its README also notes that the Helm chart still targets legacy images, so deployment methods may differ in version and architecture.
