Hey Product Hunt! 👋 I’m Erwin, the founder of CrispCheck. A few months ago, my Let’s Encrypt certificate expired on a client project. Chrome started showing the “Not Secure” warning. I didn’t find out until a customer screenshot landed in my inbox. That was the moment I realized I was using three separate tools for uptime monitoring, SSL tracking, and a status page and none of them talked to...

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.

Every time you leave your pet with a sitter, you end up sending a wall of texts — feeding schedule, vet number, medications, emergency contacts, behavioral quirks. Half gets buried.

They can tap to call the vet, check medication dosages, and see the full routine in seconds.

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...
