Know your connection
A clearer view of
your internet speed.
Download and upload, measured separately. Then see how HTTP responsiveness changes when both directions are active.
Test this connection
One test transfers 70 MiB of payload, plus protocol overhead. Mobile data charges may apply. Other network activity can affect results.
Ready. No test starts until you choose Start.

Capacity to this server, measured in separate directions. Not a definitive rating of your internet line.

One service. Two ways to measure.
Use this page on its own, or use the internet-speed skill with your AI agent. Both follow the same sequence: idle probes, download capacity, upload capacity, then simultaneous load. This page does not use an AI model.
Results describe a bounded transfer to our server on Codimeo, not every destination. HTTP timing includes browser scheduling, connection reuse and server processing. It is not raw network RTT. Timing variation is not packet jitter, and failed HTTP probes are not packet loss. These results alone do not identify a Wi-Fi, ISP or server fault.
No accounts, cookies, trackers, IP lookup or saved measurement history. Results stay in this page and disappear when you leave or reload. The server processes your connection to perform the test.
