Migrate from Heroku Scheduler

List your Heroku Scheduler tasks

Open your Heroku app → More → Scheduler. Note each task's command and schedule (10 min, hourly, or daily).

Expose tasks as HTTP endpoints

For each scheduler task that runs a command, add a protected HTTP route to your app that performs the same action.

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

Deploy your changes

Deploy the new routes to Heroku. Test each endpoint manually.

Create JustRun jobs

For each task, create a JustRun job: paste the endpoint URL, set the matching schedule. Use the visual wizard or CLI: npx @justrun/cli create.

Set up escalation policies

Configure Slack, Discord, or PagerDuty alerts in JustRun. Heroku Scheduler has no failure alerting.

Disable Heroku Scheduler tasks

Once JustRun jobs are verified, delete each task from Heroku Scheduler.
