Healthchecks

Healthchecks receives HTTP or email “pings” from scheduled jobs and compares the arrival time to a user‑defined period and optional grace interval. If a ping is missing or arrives after the grace window, the service marks the check as late or down and triggers notifications through any of its more than twenty built‑in integrations. A web dashboard shows the current state of all checks, an event log, and configurable tags, while public status badges can be embedded in documentation or status pages.

The system is built with Python 3.12+, Django 6.0 and supports PostgreSQL, MySQL or MariaDB as a backend. It can be run as a self‑hosted application using the provided Dockerfile or pre‑built images, and it also offers a hosted version at healthchecks.io. The project is released under the BSD‑3‑Clause license and includes features such as cron‑expression scheduling, WebAuthn two‑factor authentication, and team management with read‑only access.

Healthchecks is aimed at developers and operations teams that need reliable monitoring of cron jobs, background workers, or any periodic task. Its open‑source, self‑hostable nature and free tier make it suitable for small installations as well as larger deployments that require custom integration and on‑premises control.
