Check Time To First Byte (TTFB) and key network timings for one or more URLs.
About This Tool
The TTFB Checker helps you measure your website’s Time To First Byte — the time your server takes to respond with the first byte of data after a browser request.
It’s perfect for website owners, developers, SEOs, and performance teams who want to improve server speed, Core Web Vitals, and overall user experience.

-
Check TTFB for any URL instantly

-
Compare TTFB across pages
-
Identify performance bottlenecks (backend, DNS, CDN, caching)
-
Improve Core Web Vitals and SEO

Still Have Questions?
TTFB (Time To First Byte) is the time taken for a server to start responding after a request is made.
Slow hosting, no caching, heavy backend processing, slow database queries, large server load, and missing CDN.
Yes. A slow server response can hurt page speed and Core Web Vitals, which impacts rankings and user experience.
Use fast hosting, enable caching, optimize WordPress, reduce plugin load, use CDN, and optimize server configuration.
