Migrate from Render Cron Jobs

List your Render Cron Jobs

In your Render dashboard, navigate to your project and note each Cron Job service: its command, schedule, and Docker image or build command.

Expose cron logic as HTTP endpoints

Add HTTP routes to your Render web service for each cron task.

// Express
app.post('/cron/cleanup', verifySecret, async (req, res) => {
  await performCleanup();
  res.json({ ok: true });
});

Create JustRun jobs

Create a JustRun job for each Render Cron Job: point it at your Render web service URL + cron route, with the same schedule.

Add a shared secret header

In JustRun, add an Authorization or X-Cron-Secret header. Validate it in your route handler to reject unauthorized calls.

Delete Render Cron Job services

Once JustRun jobs are verified, delete the Render Cron Job services to stop incurring their compute costs.
