The Open Observatory of Network Interference (OONI)
is a free software project that aims to empower decentralized efforts in increasing transparency of Internet censorship around the world.
Our mission is to ensure a free and open Internet by increasing transparency of Internet censorship around the world.
We believe that everyone should have equal and open access to information. We aim to help create and defend an Internet where human rights -- particularly freedom of expression and access to information -- are promoted and protected around the world.
We know that we can’t do this alone. This is why we have built a decentralized, citizen-led, Internet censorship observatory.
We create free and open source network measurement tools that anyone can use to measure Internet censorship.
We openly publish measurements to provide a public archive on network interference and to increase transparency of Internet censorship around the world.
All of our methodologies, tools, and measurements are entirely open, transparent, and peer-reviewed.
By increasing transparency of internet censorship, we aim to support public debate on information controls and promote social justice on the Internet.
What we do
Since 2012, we develop free and open source software, called OONI Probe, that you can run to measure:
- Blocking of websites;
- Blocking of instant messaging apps (WhatsApp, Facebook Messenger and Telegram);
- Blocking of censorship circumvention tools (such as Tor and Psiphon);
- Presence of systems (middleboxes) in your network that might be responsible for censorship and/or surveillance;
- Speed and performance of your network.
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.
In near real-time, we analyze and openly publish all network measurements on OONI Explorer and on the OONI API, arguably the largest publicly available resources on Internet censorship to date.
