About

The Open Observatory of Network Interference (OONI) is a free software project under The Tor Project which aims to empower decentralized efforts in increasing transparency of internet censorship around the world.

We develop free and open source software, called OONI Probe, that you can run to measure:

By running OONI Probe, you can collect data that can potentially serve as evidence of internet censorship since it shows how, when, where, and by whom it is implemented.

Thanks to our global community, millions of network measurements have been collected from more than 200 countries since 2012. All network measurement data is published on OONI Explorer and on the OONI API, arguably the largest publicly available resources on internet censorship to date.

Prior to running OONI Probe, please read our Data Policy and documentation about potential risks.
