Open-source internet quality test

Test your connection under real load

Ordinary speed tests do not tell you whether the connection stays usable when it is busy.

This bufferbloat test creates download and upload load, then checks whether delay stays under control. The result shows how the connection behaves in the moments that make calls, games, browsing, and streaming feel smooth or frustrating.
