I run a hosting company and keep seeing the same blind spot: founders optimize their SaaS for their own region, then miss performance issues affecting users halfway across the world.
Most TTFB tools test from 5-10 locations. That's not enough to catch real global bottlenecks.
So I built a free tool that checks your website's Time to First Byte from 114 countries simultaneously.
What you get:
- Response times across 6 continents
- Status codes per location
- Geographic latency breakdown
- No signup required
What I've learned from running it:
- Latency varies way more than people expect. Same site, 200ms in one country, 2s+ in another.
- A lot of sites return errors in specific regions without the owner knowing.
- CDN placement is often guessed, not data-driven.

Would love feedback from anyone running a global SaaS — is this data useful? What would make it more actionable?
