Railway cron jobs

Railway cron jobs for fixed schedules

Railway cron jobs are useful for short-lived tasks that run on a fixed schedule and exit cleanly. CronCoco is a better fit when your app needs to create, update, pause, or inspect recurring webhooks as product data.

When Railway cron jobs are enough

Railway works well when you have a small number of known schedules owned by the application team. Typical examples are nightly cleanup, periodic cache warming, daily exports, or maintenance tasks that are configured once and rarely change.

The platform runs a service on the cron expression you configure, expects that process to finish its task, and then expects it to exit. That model is straightforward when the schedule is static and the work is operational.

Current constraints to account for on Railway

Railway's current cron model has a few practical limits. Schedules run in UTC, the minimum interval is five minutes, and execution time is not guaranteed to land exactly on the minute. If one run is still active when the next one is due, the next run is skipped.

Why product-owned schedules break the model

Many SaaS products need one schedule per tenant, integration, workspace, or user. A report might run every Monday for one account, every day for another, and be paused temporarily for a third. Those schedules belong in your application data model, not in one platform settings screen.

Once recurring work becomes dynamic, you usually need create, update, disable, and delete operations from your backend. You may also need custom payloads, authentication headers, and job history tied to a specific customer workflow.

A practical split: Railway for handlers, CronCoco for timing

A common pattern is to keep your application endpoint on Railway and move the clock to an external scheduler. Your app exposes a protected route, then creates schedules through an API when product events happen.

// Example Railway-hosted webhook handler
export async function POST(request) {
  if (request.headers.get("x-cron-secret") !== process.env.CRON_SECRET) {
    return new Response("Unauthorized", { status: 401 });
  }
  const payload = await request.json().catch(() => ({}));
  await runTenantWorkflow(payload.tenantId);
  return Response.json({ ok: true });
}

Creating the schedule through CronCoco

With CronCoco, your backend can create the schedule when a customer turns on a feature, changes a cadence, or reconnects an integration. The returned job id can live next to the tenant or workflow record in your database.

curl -X POST https://api.croncoco.io/jobs \
  -H "Authorization: Bearer coco_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name":"tenant-report-acme","cron_expression":"0 14 * * 1","webhook_url":"https://your-app.up.railway.app/api/reports/run","headers":{"x-cron-secret":"YOUR_SECRET"},"payload":{"tenantId":"tenant_123"}}'

Rule of thumb

Use Railway cron jobs for fixed infrastructure or maintenance tasks. Use CronCoco when recurring work is part of your product and your backend needs to manage schedules programmatically.
