Tech Stack Visualization / Monitoring Tool?

Same as title. As a full stack web developer who sometimes procastinate my full-time job to create my personal projects, I wonder if there are any tools out there to visualize and monitor my tech stacks. I want it to be as lightweight as possible, and quickly see the server status (sometimes simply down or up) at each layer (e.g. front-end, back-end, database etc)

I have seen the tool CloudCraft, but it seems to only work with AWS, but I’m running my stacks almost entirely on Netlify / Vercel, so it’s of no use to me.

Any input is hugely appreciated!
