Supabase

Created https://checkify.io with Supabase. A super simple uptime checker for small to medium websites which can’t afford the enterprise solutions.

I'm wondering if this is a side project and if you actually earn a little money with it 🙂

I'm always struggling to monetize side projects, but yours look useful and has a fair pricing!

Yes, we have around 20 paying customers. So I actually make a little profit. It’s a side project which launched recently to the public. I am glad you like it!
