I am currently building a suite of Dev Tools for Makers which won't have any major features limited by pricing.
I started with this Uptime Monitor, You can use it to monitor any url every minute. I'll add more custommizations and features soon!
Fun Fact: The MVP is built entirely on Google Sheets. I'm still working on the code version cause I want a web dashboard, but till then, This is atleast working, and it only took me 15 minutes to go from Idea to live
