Open Nettest is an open source network measurement tool that allows users to test their internet performance and censorship. It measures speed, latency, blocking, and more.

What is Open Nettest?

Open Nettest is an open source network measurement tool developed by the Open Technology Fund. It allows users to test their internet performance and detect censorship or traffic manipulation.

Some key features of Open Nettest include:

  • Speed tests - Measure download and upload speeds.
  • Web connectivity - Test if websites are blocked or filtered.
