Are websites and social media apps blocked? Is your network unusually slow? Run OONI Probe to find out!

With this app, you will examine the blocking of websites and instant messaging apps, measure your network's speed and performance, and check whether systems that could be responsible for censorship and surveillance are in your network.

OONI Probe is developed by the Open Observatory of Network Interference (OONI), a free software project (under The Tor Project) that aims to uncover internet censorship around the world.

Since 2012, OONI’s global community has collected millions of network measurements from more than 200 countries, shedding light on multiple cases of network interference.

▶ Collect evidence of internet censorship You can check whether and how websites and instant messaging apps are blocked. The network measurement data you will collect may serve as evidence of internet censorship.

▶ Detect systems responsible for censorship and surveillance OONI Probe tests are also designed to uncover the presence of systems (middleboxes) that could be responsible for censorship and surveillance.

▶ Measure the speed and performance of your network You can measure the speed and performance of your network by running OONI's implementation of the Network Diagnostic Test (NDT). You can also measure video streaming performance with the Dynamic Adaptive Streaming over HTTP (DASH) test.

▶ Open data OONI publishes network measurement data because open data allows third parties to verify OONI findings, conduct independent studies, and answer other research questions. Openly publishing OONI data also helps increase transparency of internet censorship around the world. You can explore and download OONI data here: https://ooni.io/data/

▶ Free software All OONI Probe tests (including our NDT and DASH implementations), are based on free and open source software. You can find OONI software projects on GitHub: https://github.com/ooni. Curious to learn how OONI Probe tests work? Learn more: https://ooni.io/nettest/

Outdated tests
     
by BłøøÐŁůsT · January 23, 2018

Your web connectivity test includes ExtraTorrent.cc, which has not existed since last year, when the admins surprisingly decided to shut the doors without warning. I don't know how many other non-existant sites are listed in your tests but, you should update the lists to make the tests accurate.

Speed rates need to be corrected
     
by Travellinggilberry · January 28, 2018

Misleading rate of speed in tests reporting speed. Given the numbers being reported, speed should be mbs (megabits per second) not MBs (Mega Bytes per second). To get MBs you would need to divide the reported number by 8.

Needs sites update
     
by Pagan Poetry · November 3, 2025

Multiple sites need update. Ex:feedtheminds [.] org is now defunct and has been hacked so scanning it is pointless.

Great opportunity to volunteer!

This is a great way to contribute to helping internet freedom!

App works well

You guys are awesome! Keep up the good work. Full transparency is great in a digital age. Useful utility for debugging Dev projects. Domo arigatou!

Crashing Problems
     
by Thanky U · August 27, 2023

1) During tests, specifically website tests, it crashes sometime in the middle, after about 300 sites. Time limit was turned off. iPad Air iOS 12.5.7 2) Page of categories of websites. Ellipses on top right always causes a crash. On this iPad and a newer one too. The premise is good, but the constant crashing is a bummer. 3) Needs a landscape view orientation.

Freedom
     
by Squirlnutz · October 22, 2019

I use every app made from this developer I can. This app’s developer goes through great lengths for our freedoms not just with this one application.

Not a fan of the new update
     
by J0hn-F. · January 16, 2019

I’m not a fan of this new update. It takes several minutes of actively waiting on your phone in order to run the tests. I can’t just hit run a few times and execute all the tests
