System Tests
See your PC specs and test your internet speed in the browser. Check CPU, memory, GPU, screen, then measure download, upload, ping and bufferbloat. No install.
This is the catch-all for what your browser can measure about your machine and your connection. Speed test, system report, webcam check, all in one tab.
Most speed tests hand you a big download number and stop. That's the least useful number for gaming and calls. Ping is the round trip to the server. That's what decides if your shot registers before you die. Bufferbloat is different: it's your ping spiking when someone else on your network starts a download. A 500 Mbps line with a ping that triples under load feels worse online than a 50 Mbps line that stays steady. Run it and you get ping, jitter, bufferbloat, and download, ranked by what actually matters.
The system report tells you what the browser is allowed to see, and that's less than you might expect. Core count and rough memory come through. The GPU name comes through. The exact CPU model doesn't, because browsers don't expose it. That's a deliberate privacy limit, not a bug. It's good for a quick sanity check before a call or a support ticket, not a replacement for a tool like CPU-Z. The webcam test is simpler: it shows your live feed so you can confirm the camera and its permission work before you join a meeting.

Webcam Test
Test your webcam in the browser. See a live preview, read the real resolution and frame rate, switch cameras, and grab a snapshot. Nothing is uploaded.
Bufferbloat Test
Test your connection for bufferbloat in the browser. See how far your ping climbs under load, get an A+ to F grade, and learn if a busy line will lag your game.

Bufferbloat: Why Your Ping Spikes When Someone Streams
Your ping sits at 15 ms until someone starts a stream or a cloud backup, then it jumps to 200. That spike is bufferbloat. Here is why it happens and the fix.

Ping vs Download Speed: Which Matters More for Gaming?
Download speed and ping measure completely different things. One fills a progress bar; the other decides if your shots land. Check the right number first.

FAQ
- What is a good internet speed?
- 4K streaming needs around 25 Mbps down. A video call needs 3 to 5 Mbps, and the upload matters as much as the download. Gaming barely uses bandwidth at all. Once you're above 20 Mbps, the download number stops mattering and ping takes over. Chase the right metric for what you actually do. Test your internet speed
- Ping or download speed: which matters more for gaming?
- Ping, almost always. Download speed fills a progress bar, but ping is the round trip that decides if your shot registers before you die. Once you're above 20 Mbps, more download does nothing for your game. A low, steady ping does. Ping vs download speed for gaming
- What is bufferbloat and why does it matter?
- Bufferbloat is your ping spiking when the connection is busy. Your line might ping at 20 milliseconds idle, then jump to 200 the moment someone starts a download or an upload. That spike is what makes a game rubber-band even on a fast plan. The test measures ping while loading the line so you can catch it.
- Why is my speed test slower than the plan I pay for?
- Usually Wi-Fi or the browser, not the plan. Test over Ethernet first. If the wired number matches your plan, Wi-Fi is the bottleneck. A browser test also runs in a single tab, which can cap results above roughly 500 to 700 Mbps. Run it three or four times at different hours and test wired before you call your provider.
- Can the browser read my full PC specs?
- Only part of them. The system report shows your screen resolution, core count, rough memory, and the GPU your browser exposes. It can't read the exact CPU model, storage, or serial numbers, because browsers hide that for privacy. It's a fast profile of your machine, not a full spec sheet. Check your system info
- How do I test my webcam in the browser?
- Open the webcam test and allow camera access. A live picture means the camera works at the hardware and browser level, so any failure in a meeting app is that app's settings. No picture usually means a denied browser permission or another app has the camera locked. Webcam not working? How to fix it
