How to Know If Your App Is Actually Working (Without Checking Every 5 Minutes)
Built an app with AI? Here's how to set up alerts so you know the moment something breaks.
Quick diagnostic
Three things to check first
Check the trigger
Look at the last successful run. If the trigger hasn't fired since, the issue is upstream — a webhook URL changed, a cron schedule was edited, or the source system stopped sending events. Start here before you look at the workflow itself.
Check the credentials
OAuth tokens expire quietly. API keys get rotated by a teammate who didn't know they were in use. A service account password changes upstream. Re-connect the integration that touches the step where the chain broke and try again.
Check the logs
Open the most recent failed run. The first red step is where the chain broke — usually a field name that changed in the source data, a rate limit that kicked in, or a timeout talking to a downstream service. Fix that one step and the rest of the chain usually recovers on the next run.
The fact that you're Googling this means you're doing what every
vibe-coder does at some point: manually refreshing your own app
every few hours because you don't trust it, can't sleep without
checking, and have been burned by a silent failure at least
once. There's a better way — and it doesn't involve setting up
your own infrastructure.
Three approaches, ranked by how well they actually work. The
lightest is a browser-based page-load check — a URL-ping
service hits your URL on a schedule and tells you if
it's returning 200. This catches the case where your whole app
is down, but it misses the ones that matter most for vibe-coded
apps: auth breaking, Supabase disconnecting, Stripe quietly
failing. Your site returns 200 OK while paying users can't log
in.
The medium approach is writing your own health-check script
that calls your critical endpoints and checks the response
shape. This works until the script breaks, or you forget to
update it when the API changes. Most vibe-coders give up on
this within a week.
The approach that actually fits vibe-coded apps is to watch the
user-visible flows — signup, login, data loads, payment — from
outside the platform, every few minutes, with plain-language
alerts. That's NoCrash. Zero code to install, zero dashboards
to check, one morning message covering every flow that matters,
and a Telegram or email alert the moment something breaks.
The pattern
Most of these fail quietly.
Here’s the pattern: most automation and vibe-coded apps fail quietly. No alert, no error — just silence, until a customer notices. NoCrash watches your tools from outside and tells you in plain language, every morning, what ran clean and what didn’t. Peace of mind, not a log dump.
Stop finding out from your customers.
