For vibe coders & AI builders

You vibe-coded an app. Now keep it alive.

Your AI builder helped you launch fast. Holter adds the production layer it probably skipped: uptime checks, SSL/DNS monitoring, API health, cron and backup heartbeats, and alerts you'll actually see.

Monitor my AI-built app Start with the deploy checklist

You might be here because…

You shipped with Claude Code, Cursor, Lovable, Replit, Bolt, v0, or another AI builder.
The app is live, but you are not totally sure what happens if it breaks at 2am.
You know you should monitor something, but "observability" feels like a whole other job.
You do not want to learn Prometheus, Datadog, Grafana, or SRE vocabulary just to know if your app is down.
Your AI helped generate the app, but it did not set up the boring production checks.
You want the shortest path from "deployed" to "watched."

Your world

Shipping was the fun part. Production is where the app becomes real.

Vibe coding makes the first version feel instant. You can go from idea to working product before the weekend is over. But once real users can touch it, the risk changes. A broken route is not a local bug anymore. An expired certificate is not a TODO. A cron that stops running can quietly break billing, emails, backups, reports, or onboarding.

You do not need an enterprise observability stack. You need a simple answer to: is my app up, is it healthy, are the invisible jobs still running, and will I hear about it before users do?

The things AI-built apps usually skip

✗ Uptime: your homepage or app route starts returning errors.

✗ API health: the frontend loads, but the API is broken or slow.

✗ SSL and domain: the app is fine, but the certificate or domain expires.

✗ DNS: your domain stops resolving after a provider change.

✗ Crons and queues: background work stops while the app still appears up.

✗ Backups: a nightly backup fails for days and nobody notices.

✗ Alerts: errors exist somewhere, but they do not reach you.

Start with these five monitors

01 Homepage or health endpoint.
02 API endpoint.
03 SSL certificate and domain.
04 DNS record.
05 One heartbeat for the most important background job.

Free gives you enough room to cover the basics. Start with the five checks above, then add status pages, third-party dependencies, and global response checks when the app has enough users to justify them.

Your coding agent can help find what to monitor

If you already use Claude Code, Cursor, or another MCP-capable agent, connect it to Holter with a team-scoped token. Your agent reads your repo locally, finds routes, health checks, scheduled jobs, queues, and domains, then proposes monitors and heartbeat code. Holter never sees your source code. You review and approve what gets created.

You do not need to become an SRE this week

Logs, metrics, traces, dashboards, hosts, agents, collectors, and alert rules all have their place. But that is too much when your immediate question is "will I know if this new app breaks?" Holter is intentionally narrower: uptime checks, heartbeats, alerts, and status pages. Enough to cover the failures users notice first.

After setup, you should know:

✓ whether your app is responding,
✓ whether your API is healthy,
✓ whether SSL/DNS/domain basics are safe,
✓ whether a critical background job ran,
✓ where alerts will reach you,
✓ and what to add next.

Questions, answered

Start with five: your homepage or health endpoint, your API, your SSL certificate, your DNS/domain, and a heartbeat on your most important background job. Holter sets each up in a few clicks.

No. Holter checks your app from the outside, and your jobs ping it for the rest. If you use the MCP flow, your agent reads the repo locally — Holter only receives the monitors it proposes.

Yes. Connect Holter's MCP server with a team-scoped token and your agent proposes monitors and heartbeat code from your repo, locally. You review and approve.

No. There's nothing to install on your servers — Holter watches from the outside and your jobs send a heartbeat for the parts it can't see.

Yes. Free covers up to 5 monitors with no card — enough for the starter checklist. Upgrade when the app has the users to justify it.

No, and it's not trying to be. Holter is the narrow layer that catches the failures users notice first — is it up, is it healthy, did the jobs run. Add logs and error tracking alongside it when you need depth.
