Built a tiny tool after the Cloudflare outage - would love honest feedback
The other days Cloudflare outage wasted a few hours of my day - not because the outage was confusing, but because my monitoring stack was basically gaslighting me.
Everything lit up red.
Every “DOWN” alert fired.
But none of it told me whether the issue was:
my origin
Cloudflare’s edge
DNS
SSL
routing
My servers were fine the whole time.
It made me realise most monitoring tools don’t distinguish origin failures from CDN/edge failures — so one vendor issue looks like a total infrastructure meltdown.
So I hacked together a small tool that does a clean diagnostic:
Enter a URL and it checks:
origin health
Cloudflare/Vercel/AWS edge
DNS
SSL expiry
CDN failure patterns
Not trying to hype anything — I literally built this out of frustration and I’d genuinely love feedback from folks here.
What would you expect a tool like this to detect?
Any edge cases I should add?
Would appreciate honest thoughts.

Hey, I just used your tool. I love it! It was super quick and accurate. I'm not sure what much more you can do, but I have a feeling it's a missing a feature or two really set it apart from down detector.
I would challenge you to hone in on your differentiating factor and hammer it home.
@r221 Thanks Rob, Will look into this

Hey Rob - appreciate the push. I’ve tightened the positioning and made the differentiator way more obvious. Just shipped this update that makes it clear.
StayUp highlights the layers it detects (origin vs edge vs DNS vs SSL), so now it’s clear what makes it different from basic uptime pings.
