What you see. The app breaks for hours before a customer emails you, and you cannot tell when it started or why.
Why it happens
AI builders produce an app, not an operation. Nothing watches it. You have no uptime check, no error tracking, and nobody looks at the host logs. So the first monitor is your customer.
The pieces exist and most are free to start. Vercel Observability is on every plan and shows error rate and logs per route. Supabase keeps logs for the API, Postgres, Auth, Storage and Edge Functions under Logs in the dashboard. An error tracking tool like Sentry can send a message to Slack or email when a new issue appears from a real user's browser or your functions. On top of that, a Free Plan Supabase project can be paused after seven days of low activity, which looks exactly like an outage to users. Monitoring is the difference between a five minute fix and a weekend of lost sign-ups.
Fix it yourself
- Set up an uptime monitor that loads your home page and one API route every few minutes and alerts your phone. Many have free tiers. Add your sign-in page too.
- Add an error tracking tool to the frontend and your functions. Ask your builder to install it and have it alert you on every new issue. Set the alert channel to email or Slack.
- Open the host dashboard once a week. On Vercel use Observability and sort routes by error rate. On Supabase open Logs and check Auth and API Gateway.
- Keep the database awake. Move the Supabase project to a paid plan before launch, or at least know that free projects pause after a week of low activity.
- Write a one-page runbook: where the logs are, how to roll back to the previous deployment on your host, and who to call. Keep it outside the app.
- Subscribe to the status pages of your providers so you can tell their outage from yours.
When to get an engineer
Get help when you want someone else to be woken up. Ongoing care at $100–$5,000 a month usually includes uptime checks, error alerts, dependency updates and a monthly look at the logs. A one-off check at $49–$800 can set up monitoring and leave you the dashboards. Tell them your host, your database, and which flows matter most, usually sign-up, sign-in and payment.

Check these
Errors reach you before users do
Add error monitoring and uptime alerts. If you learn about outages from customers, this is missing.
Database backups run automatically and a restore has been tested
Check what your database plan actually includes, then restore a backup into a test project once.
Secrets live in the host's environment settings
Keys belong in environment variables on the server, not in the repository or in front-end code.
Key pages load fast on a phone
Run PageSpeed Insights on the home page and the main app screen, on mobile.
Questions
Is this worth it for an app with fifty users?
Yes. Fifty users who hit a broken sign-in and leave are hard to win back, and the free tiers of these tools cost nothing.
What is the difference between uptime and error tracking?
Uptime tells you the site is unreachable. Error tracking tells you a button fails for some users while the site is up. You need both.
