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

Healthchecks monitors cron jobs and scheduled tasks by receiving HTTP or email pings and alerting when expected pings are late or missing. It includes a web dashboard, API, notification integrations, 2FA, and team features.

Features and best fit

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

Monitor expected schedules with period/grace settings or cron expressions

Each check can use an expected interval plus grace time, or an explicit cron expression.

Sources: [2][3]

Send missed-run alerts through many notification integrations

Missing pings can trigger notifications while the dashboard and event logs provide operational visibility.

Sources: [2][3]

For adding dead-man's-switch monitoring to cron, backups, and scheduled jobs

Existing jobs only need to send pings, so the execution platform can remain unchanged while monitoring is added.

Sources: [2]

Operate the monitor's own email, database, and availability dependencies

Self-hosting requires configuration such as SMTP and persistence. Teams should also consider how they detect failure of the monitoring service itself.

Supplemental curator note

Healthchecks deliberately focuses on whether scheduled work ran on time rather than replacing general application monitoring. Existing cron jobs or backup scripts can integrate by sending a simple ping to a generated URL.
