What is OONI Probe?

OONI Probe is a powerful anti-censorship tool created by enthusiasts and supported by users who fight for a free internet. Along the way, the application will help analyze the quality and speed of the Internet connection.

It seems that the struggle between government agencies trying to control the global network and users who are not satisfied with this approach will continue forever. The presented tool acts as another assistant in identifying resources and means of communication that are subject to blocking.

It is worth noting that the application is not used in anonymous mode, which the developers warn about during the first launch. In other words, the platform publishes data that can help interested parties to identify the user, such as their IP address, date and time of verification.

Features:

  • an additional tool for analyzing the speed of the Internet connection;
  • saving the history of the results of the checks carried out;
  • concise interface design.

If you are not afraid of the above warning, then select the required function through the interface OONI Probe and start testing sites, means of bypassing blocking ( Psiphon , Tor , VPN) and instant messengers. In the first case, it is enough to enter a link in a special field, in the rest, the program will check automatically, and the user will only have to familiarize himself with the result.
