Your app is up. But is it working?
SilentWatch catches the failures your uptime monitor can't see: missed Stripe webhooks, dead cron jobs, and broken signup flows. One ping URL or event call, and we tell you the moment something stops happening.
5 checks free forever. Upgrade when you need more.
Things that break and nothing tells you
Stripe webhook stops firing
Your endpoint 500s after a redeploy. Invoices pile up. You find out when a customer asks why they were charged but not upgraded.
Cron job silently dies
A dependency bump breaks your nightly job. No error page, no crash log you're watching. It just... stops running.
Signup flow breaks
A deploy ships a bug in your onboarding email. Signups keep trying, but nothing completes. Your dashboard looks fine. Growth doesn't.
One ping. That's the whole integration.
Add a single line at the end of your job, webhook handler, or signup flow. No SDK, no agent, no config file to maintain.
- ✓ Works from curl, cron, GitHub Actions, Vercel Cron, Supabase Edge Functions
- ✓ Grace periods so a slow run doesn't false-alarm you
- ✓ Recovery emails so you know when it's fixed, not just when it broke

Heartbeat checks
Give any cron job, webhook handler, or scheduled task a ping URL. If it goes quiet past your grace period, you get an email before your customers notice.
Business-event checks
Alert when signups, payments, or any event you define drop below a threshold in a time window — not just when a server crashes.
Stripe webhook relay
Point a Stripe webhook at SilentWatch and we'll track invoice.paid and checkout.session.completed by type, so a silent Stripe integration gets caught fast.
Monday digest
One email every Monday with every check's status, downtime, and event counts for the week. No dashboard-checking habit required.
