Today, the OONI team released OONI Probe Web: a new browser-based tool for measuring the blocking of websites. 

Run OONI Probe Web: https://probe-web.ooni.org/

We built OONI Probe Web in response to long-term community feedback, requesting a censorship measurement tool that can be run from a browser, without requiring the installation of any software. 

With OONI Probe Web, you will test the same types of websites as with the OONI Probe apps. You can find which websites you would test here: https://ooni.org/support/faq#which-websites-will-i-test-for-censorship-with-ooni-probe

Upon running OONI Probe Web, your test results will be published as open data in near real-time: https://ooni.org/data/

However, please note that OONI Probe Web is very limited in comparison to the OONI Probe apps (https://ooni.org/install/). 

Due to limitations in the API available to web browsers, it’s not possible to run advanced experiments necessary for accurately detecting and characterizing website blocks from a browser. 

We therefore kindly ask you to not treat OONI Probe Web as a replacement for the OONI Probe apps, but as a complementary tool.

We encourage you to run OONI Probe Web and contribute measurements, the analysis of which will help us improve upon OONI Probe Web on an ongoing basis.

You can learn more about OONI Probe Web in our blog post: https://ooni.org/post/introducing-ooni-probe-web/

We welcome your feedback, and we're happy to address any questions.

Thanks,

Maria (on behalf of the OONI team).
