Network Information Test
Read the connection info your browser exposes — online state, effective type and estimated RTT/downlink. Clearly labeled estimates.
These values come from the Network Information API where supported. Downlink and RTT are coarse browser estimates, not precise measurements, and support varies by browser.
01How this test works
Network tests stay deliberately small and self-contained. Latency and stability tests send tiny requests to this site’s own server and time how long the round trip takes; the information test reads what your browser can tell us about your connection.
We only ever measure against our own server, never anyone else’s, and we space the requests out so the test stays gentle on your connection. Everything stops the moment you leave the page.
These are estimates of your connection to this website — not a full internet speed test, and not a measurement of any other service.
02How to use it
- Open the test — no permission is required.
- For latency or stability, press Start and let the samples collect.
- Watch the median, jitter and any failed requests update live.
- Press Stop at any time; the test also aborts if you navigate away.
03What this test covers
What it detects
- Round-trip latency and jitter to this website’s server or CDN
- Dropouts and timeouts over a chosen duration
- The browser’s online state and, where exposed, effective connection type
- Coarse browser estimates of downlink and RTT
What it can’t detect
- Your true internet download/upload speed (this isn’t a full speed test)
- Latency to services other than this website
- Problems inside your ISP’s network beyond what round-trips reveal
04Troubleshooting
| Symptom | What to do |
|---|---|
| High or spiky latency | Try a wired connection, move closer to your router, and close bandwidth-heavy apps. |
| Frequent failed requests | You may be offline or behind a captive portal; check other sites and your Wi-Fi. |
| Connection info shows nothing | Not every browser can share connection details; that’s expected. |
| Results vary each run | Latency naturally fluctuates with network load and distance to the server; take several samples. |
05FAQ
Is this a full speed test?
No. We intentionally keep network tests lightweight and measure only against our own server.
Does it contact third parties?
No. Only this site’s own server is used.
Why do results vary?
Latency depends on your connection, distance to the server, and current load, so values fluctuate.
Does it use a lot of data?
No. Requests are small and rate-limited, and the test stops when you leave the page.
Why is latency higher than a ping tool?
A browser request includes extra processing the operating-system ping skips, so it can read a bit higher.
Can I trust the effective connection type?
Treat it as a coarse hint. It’s a browser estimate with limited, varying support.
