Free internet speed test with bufferbloat, jitter & grades

Check.Fast is a free, no-signup internet speed test that goes beyond basic results. It measures download, upload, ping, jitter, bufferbloat, loaded latency, packet loss, and connection stability with easy-to-understand A–F grades. Built for real users — gamers, remote workers, streamers, and anyone tired of slow connections that basic tests don’t explain. No ads. No accounts. Works instantly in your browser on any device. Get honest insights into your real-world internet performance.
One thing that would make this way more useful for me is a history view that tracks my results over time, so I can see if my ISP is actually delivering consistent speeds or quietly throttling during certain hours. Would love to bookmark a single dashboard and spot the patterns.
@sedat1276640 Hello Sedat, Thanks for the suggestion! 🙌 Check.Fast already saves your previous tests. After your second test, a “Your Recent Tests” section automatically appears with your past results, a download trend chart, and comparisons with your last test.

the A-F grading system is genuinely clever, way easier to glance at than a wall of numbers and you actually understand what bufferbloat means afterward.
