Cronhq

Cronhq is a hosted scheduler aimed at developers who need HTTP calls on a timetable, without running cron servers of their own. Jobs are set up with a REST API, the dashboard, or a cronhq.yaml file that a command-line tool syncs, using a five-field cron expression plus a time zone and the URL to call.

What Cronhq offers

• Single claimed runs: a Postgres lock is meant to stop two workers firing the same scheduled run.
• Retries and logs: failed calls are retried with a per-job delay, and each attempt is logged with its status code, duration and a truncated response body.
• Signed requests: each request carries an HMAC-SHA256 signature made with a per-job secret.
• Heartbeat monitors: a job pings Cronhq on each run, and Cronhq alerts when a ping is late.

Who it works with

Developers scheduling webhook or HTTP calls who want alerts by email or Slack.

Key facts

• Alerts: sent on the third failure within an hour, and again on recovery.
• Build: written in Rust on Postgres, at version 0.1.
• Self-hosting: the pricing page offers a self-hosted container under the MIT licence, but the GitHub repository it links to returned not found, and the npm package in its install command is not on the npm registry.
