Launching CrispCheck in 3 days - know when your endpoints go down before your users do

Hey everyone

I've been quietly building something for the past few months and we're launching on Product Hunt in a few days. I wanted to share it here first and get some honest feedback before we go live.

The problem I kept running into:

Every time something broke in production an API going down, a slow endpoint nobody noticed I'd find out from a user, not from my own tools. The existing monitoring solutions were either overkill (enterprise pricing, 30-minute onboarding) or too basic to be useful.

CrispCheck - Uptime, SSL and status pages in one dashboard.

Stop stitching together three tools. CrispCheck monitors your endpoints, tracks SSL expiry, and gives your users a branded status page. Free for up to 3 endpoints. Setup in under a minute.

What do you always forget to tell your pet sitter?

I built Pawzfolio because I kept forgetting to tell my sitter something important and then stressing about it the entire trip.

The most common things pet owners forget to mention:

  • Emergency vet number (not just the regular vet)

  • What to do during a thunderstorm or fireworks

  • Which foods are off limits

  • Medication timing and exact dosage

  • Where the carrier or leash is stored

  • A backup contact if they can't reach you

That's exactly why I built a structured guide so nothing falls through the cracks.
