What are you using today to monitor uptime for small or personal projects?

I run a few small services (APIs, bots and web apps) and I kept running into the same problem:

Most uptime monitoring tools are either

too expensive

too complex

or built for enterprise teams

All I really wanted was:

check if a URL is alive

know when it goes down

get notified when it recovers

see response time over time

So I ended up building a tiny tool for myself that does exactly that.

It monitors websites and APIs 24/7 and sends alerts via email, WhatsApp and webhooks.

I’m curious how others here handle this: What are you using today to monitor uptime for small or personal projects?

Your mom, every time she wakes me up I say "hold on baby let me check some stuff."
