I built a free TTFB checker that tests your site from 114 countries

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.

Try it: https://hostcry.com/tools/ttfb-checker

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