Built a TTFB checker that tests from 114 countries — here's what I learned
Launched a free tool that checks your website's Time to First Byte from 114 global locations simultaneously.
Why I built it:
Running a hosting company, I kept seeing founders optimize their SaaS for their own region, then miss performance issues affecting users halfway across the world. Most TTFB tools only test from 5-10 locations — not enough to catch real global bottlenecks.
What it does:
Tests from 114 countries at once
Shows response times, status codes, and geographic breakdown
No signup needed
What I've learned so far:
Latency varies way more than people expect (200ms vs 2s+ for the same site)
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 actually useful to you? What would make it more actionable?
What stood out to me is that you're not measuring website speed—you're revealing blind spots.
Performance data only becomes valuable when it changes a decision. Showing founders where they're unintentionally delivering a different experience to different regions feels much more useful than simply reporting another metric.
