The post-deploy checklist for AI-built apps.
Launching is not the finish line. Check your homepage, API, SSL, DNS, scheduled jobs, backups, and alerts before users find the gaps for you.

The problem
Shipping felt like the hard part — but a live app with no monitoring is one silent failure away from an embarrassing DM. There is no mystery to what breaks: the site, the API, the cert, DNS, the jobs. What is missing is a concrete checklist and something to run it for you.
Set up in three steps
Public app & API
Confirm your homepage and API respond, with the status and response time you expect.
Certs, DNS, and jobs
Add SSL and domain expiry checks, DNS resolution, and heartbeats for scheduled jobs and backups.
Alerts & status page
Route alerts to where you will see them, and publish a status page when you are ready.
What Holter does
Holter is that checklist, made real. Each item — public app, API, SSL/DNS, jobs and backups, alerts — becomes an actual monitor that watches around the clock. It is a checklist you finish once and then never think about, not monitoring theory.
- ✓ Public app — homepage / health endpoint responding
- ✓ API — status, body, and latency within budget
- ✓ SSL & DNS — valid cert, domain resolves, warned before expiry
- ✓ Jobs & backups — heartbeats that alert when a run is missed
- ✓ Alerts & status page — routed notifications and a public page
Simple, transparent pricing
