Cron jobs fail in silence. Two servers run the same crontab and your billing job fires twice. A job dies and nobody notices for weeks. Cronhq is a scheduler built around one guarantee: exactly-once execution, enforced by Postgres locks — not best-effort. Around it: retries with backoff, HMAC-signed webhooks, heartbeat monitors for jobs we don't run, and alerts that fire once on failure and once on recovery. Rust on Postgres. MIT-licensed, self-hostable, same image we run. Free tier: 5 jobs.

Could you build this?
Yes A scheduled job runner using Postgres advisory locks (`pg_advisory_xact_lock`), webhooks with HMAC signatures, and exponential backoff retry loops can be built rapidly using standard backend frameworks.
