Detect cuts in your internet connection, not just speed

I use apps to watch live sports events, and I frequently experience transmission failures. I wanted to have proof that demonstrated how the internet transmission was failing, not just the result of my internet speed but how it was maintaining bandwidth, and to know if it was the cause of the interruptions and freezes. It downloads a real TCP stream from the server, samples every 500ms to measure the throughput, and monitors if the transmission drops below 2.5 Mbps to detect interruptions.
Finally a tool that actually shows the real issue instead of just a speed number. Watching it catch a stream drop below 2.5 Mbps was super helpful for diagnosing my sports stream freezes.
Finally a tool that shows what my ISP actually does during a live match instead of just blaming my wifi. The 500ms sampling caught a real drop I never would have spotted otherwise.
Finally a tool that shows the real story behind stream drops, not just a speed number. The 500ms sampling caught micro-freezes that never showed up in my usual speed tests.
Finally something that tells me if my ISP is actually the problem or just my Wi-Fi acting up. The 2.5 Mbps threshold matches what I see in real time, and the 500ms sampling feels responsive enough to catch those freezes mid-game.
We've been measuring the internet wrong for 20 years.
That's not an exaggeration. It's literal.
Since speed tests have existed, the question they've always answered is the same: "how fast is my connection?"
But that was never the question that actually matters.
The real question is: "can my connection sustain what I actually need to do, without dropping?"
And those two questions have completely different answers.
You can have 500 Mbps, ace every speed test you run, and still watch the game freeze right at the goal, your work call cut out, buffering ruin the season finale you've been waiting weeks for.
That's not a speed problem. It's a stability problem. And the entire industry — providers, regulators, even the measurement tools themselves — has spent decades measuring the wrong variable.
I built StreamTest to answer the right question.
It doesn't measure your peak speed. It measures your connection under sustained load over 27 seconds, sampling every half second, detecting exactly when and how often your throughput drops below what's needed for HD or 4K streaming.
The result isn't a number that looks good in a report. It's a graph with timestamps — real evidence of what your connection actually does when you need it.
Because I believe change in internet service quality isn't going to come from users complaining louder. It's going to come from users complaining with better evidence.
When someone can show their provider an exact graph of their micro-interruptions instead of a vague "it keeps cutting out," the conversation changes. There are already real cases where that made the difference — a screenshot with evidence got in 48 hours what weeks of complaints couldn't.
That's the vision: measuring properly stops being a technical luxury and becomes something anyone can do in under a minute, free, no signup.
Because what isn't measured well can't be demanded well. And what isn't demanded well never improves.

StreamTest was just featured on KrispiTech — they did a detailed breakdown of how the tool detects micro-cuts that regular speed tests miss. Check it out: https://krispitech.com/why-your-speed-test-lies-how-streamtest-reveals-the-real-cause-of-stream-freezes/
