Features & Capabilities

OONI Probe is a powerful Chrome extension designed to help users detect internet censorship and monitor network performance. Developed by the Open Observatory of Network Interference (OONI), part of The Tor Project, this tool allows you to check if websites or instant messaging apps are blocked, measure your internet speed and streaming quality, and identify systems potentially responsible for censorship or surveillance within your network.

Since 2012, OONI's global community has gathered millions of network measurements from over 200 countries, providing invaluable data for transparency and research. With a commitment to free and open-source software, OONI Probe also openly publishes its measurement data, enabling third parties to verify findings and explore censorship patterns globally. Stay informed with OONI Probe to ensure open and unrestricted access to the internet.

User Reviews

OONI Probe is a free, open-source, ad-free tool that helps users test and understand network behavior and censorship. It is generally reliable and informative, but faces stability issues (crashes, freezes), lengthy scans that drain battery/data, and limited usefulness in highly censored regions due to missing proxy/list updates. Some results may be inaccurate. It remains a valuable educational tool, with room to improve stability, performance, and regional testing support.

Pros

Free, open-source software with no ads
Informative and educational about how networks and censorship operate
Works as expected and generally reliable for testing connectivity
Useful for monitoring internet access and detecting blocks/availability (open data about network behavior)

Cons

Stability issues: crashes, freezes, and bugs during testing
Long or resource-heavy scans that drain battery and data (privacy/resource concerns)
Limited effectiveness in highly censored regions due to lack of proxy support and updatable test lists
Some results may be inaccurate or outdated (sites incorrectly reported as blocked)
