How to monitor

A status page for your Next.js app

Monitor your Next.js app and API routes, catch SSR and edge failures, watch SSL expiry, and publish a custom-domain status page — in minutes, with nothing to install.

A Next.js app is more than one thing: there's the rendered frontend, the API routes, any server actions, and often a database and third-party services behind them. Each can fail on its own. Here's how to monitor a Next.js deployment and publish a status page — with nothing to install.

What to monitor

  • The app — an HTTP check on your main URL with a keyword assertion (so a blank 200 still counts as down).
  • API routes — checks on critical endpoints like /api/health (see how to monitor an API).
  • SSL certificate — expiry monitoring so a lapsed cert never takes you down (SSL guide).
  • Scheduled work — heartbeats for cron jobs, ISR revalidation, or queue processing (cron guide).

Add a health route

// app/api/health/route.ts
export async function GET() {
  // Touch the critical path — e.g. a cheap DB query.
  // await db.query('SELECT 1');
  return Response.json({ status: 'ok' });
}

Point a StatusCat HTTP monitor at /api/health with a keyword assertion on "status":"ok". If a dependency is down, make the route return a 503 so the monitor trips immediately.

Watch the edge and regions

If you deploy to the edge or multiple regions, monitor the public URL your users actually hit. StatusCat re-checks every failure before alerting, so a single cold-start blip won't page you.

Publish the status page

  1. Group your monitors (app, API, database, jobs).
  2. Create a status page and add them as components.
  3. Point it at status.yourapp.com.
  4. Enable email subscribers for incident updates.

StatusCat does all of this from the outside, free for 50 monitors, with on-call and status pages included. New to monitoring? Start with what uptime monitoring is. Running Laravel instead? See status page for Laravel.

Frequently asked questions

Do I need a package in my Next.js app?
No. StatusCat monitors from the outside over HTTP. Optionally add a lightweight /api/health route so the check exercises your critical path (database, key services).
How do I monitor Next.js API routes and server actions?
Point HTTP monitors with keyword assertions at your API routes (e.g. /api/health). For background jobs or ISR revalidation triggered on a schedule, use heartbeat monitors.
Can I put the status page on my own domain?
Yes — custom domains, private pages, subscribers and 90-day history are supported.
