Open Source Cron Monitoring (AGPL)

CronCraft's source code is public under the GNU Affero General Public License v3. You can audit it, fork it, and run it yourself.

Self-hosted deployments use SELF_HOSTED=true and skip Stripe-backed billing UI — see self-hosted cron monitoring for Docker steps.

Hosted vs self-built

The service at croncraft.app funds maintenance and support for teams that do not want to operate Postgres backups and TLS. Same codebase either way.
