Goals and Values

  1. Do one thing and do it well: alert when something does not happen on time. Focus on clean and quick UIs, reliable APIs, and user happiness. In technology choices, prefer simple and boring.
  2. Respect the user's time and privacy. Don't send marketing emails. Don't make the "Close Account" function hard to find. Don't use any JS-based analytics.
  3. Monitoring for everyone. Healthchecks.io is free for hobby use, for open source projects, and for non-profits. Healthchecks is free software, and can be self-hosted.

Open Source

Healthchecks.io is an open-source project. The code is on GitHub. It has BSD license and is accepting contributions.

Open Data

Here are a few metrics about the service (updated manually, last updated: April 8, 2021).

5 years in business
13 700 free accounts
30 open source & non-profit accounts
308 paying accounts
5 400 USD monthly recurring revenue
71 300 checks (services monitored)
21 200 000 pings processed per day
23 000 notifications sent per day

Reliability Guarantees

The service currently runs on Hetzner bare metal servers, with healthy excess capacity to handle traffic spikes. The app servers are load-balanced. The PostgreSQL database has a hot standby as well as full daily backups to S3. The database fail-over process is manual, and the ops team consists of a single person, so multi-hour or even multi-day outages are possible!

In case of incidents, we post status updates to our status page, status.healthchecks.io, and our Twitter account, @healthchecks_io.

While we can only guarantee the best effort availability, in practice, the availability has exceeded 99.9% since the service publicly launched in July 2015.
