Cron monitoring · Auto-discovery

Cron monitoring
that finds your jobs.

Drop the SDK into Hangfire, Quartz, Celery, or Laravel. Every recurring job is discovered, registered, and watched — without a single dashboard click. Alerts fire when runs miss their schedule or fail.

Monitoring made for Agents (and humans, too.)

Plug in any agent in one line — curl, MCP server, markdown docs. Built so Claude, Cursor, and your own systems can register, watch, and self-heal their own crons.

Languages & frameworks

Speaks your stack.Every language. Every scheduler.

Drop in an SDK, decorate your scheduler, or wrap any cron with a single curl. Auto-discovery does the rest.

The moat

Decorate the job. Done.

No dashboard click-through. No monitor.ping() calls per job. Add the SDK, decorate the framework — every recurring job is registered, watched, and alerted on.
