MORE ABOUT
In a time when internet access is essential and online freedom is under increasing threat in many regions, it’s important to know exactly what is happening on your network.
Whether you suspect restricted content, blocked websites, or throttled connections, this app gives you the tools to find out.
OONI Probe is a powerful open-source application that helps users measure internet censorship, speed, and interference. With just a few taps, you can run diagnostic tests to evaluate your internet service and contribute data to a global effort for transparency and digital rights. It’s a unique tool that combines technical precision with social impact.
What Is OONI Probe?
OONI Probe (developed by the Open Observatory of Network Interference) is a mobile app designed to monitor internet censorship and performance. Unlike typical speed test apps, OONI goes a step further by identifying if access to websites, instant messaging services, or circumvention tools is being deliberately blocked.
It performs a variety of tests to check the accessibility of popular sites, determine if apps like WhatsApp or Telegram are functioning properly, and see if your DNS queries are being tampered with. The results are then shared with the global OONI network, helping researchers and activists track censorship trends worldwide.
Main Features That Make OONI Probe Stand Out
What makes this app especially valuable is its combination of technical tools and human rights mission. Here are some of its most notable features:
- Website Accessibility Tests: Check if specific websites are blocked or filtered on your network.
- Instant Messaging Tests: Verify if services like WhatsApp, Telegram, or Signal are reachable.
- Speed and Performance Tests: Analyze your network’s download/upload speeds and latency.
- Circumvention Tool Testing: Evaluate access to tools like Tor or Psiphon that are often blocked in restrictive environments.
- DNS Consistency Checks: Determine if DNS responses are being manipulated or forged.
These functions go beyond typical diagnostics and provide critical insights about whether your access to information is being restricted or manipulated.
Why This Matters in Today’s Internet Landscape
Censorship isn’t just a problem in authoritarian countries. Many governments, ISPs, and organizations apply filters, restrict access to services, or throttle traffic for political, commercial, or security reasons. As a result, users often don’t know the full extent of what’s happening with their connection.
OONI Probe empowers individuals to reveal these hidden practices. By running tests on their own networks, users gain clarity—and can also contribute to a larger global dataset that supports press freedom, privacy advocacy, and digital transparency.
Easy to Use, Accessible to Everyone
Despite the complex nature of its mission, OONI Probe is designed to be user-friendly. You don’t need to be a cybersecurity expert to run tests or understand your results. The app guides you through each test, explaining what it does and why it matters.
After running a test, you get a summary of findings, including whether interference was detected, what kind of blocking occurred, and whether your ISP might be involved. The interface is clean, modern, and informative without being overwhelming.
Final Thoughts
OONI Probe is much more than just a network utility. It’s a frontline tool for defending digital freedom and promoting internet transparency. With one simple app, you can uncover hidden censorship, contribute to global research, and take an active role in shaping the future of a free and open internet.
Whether you’re a curious user or a digital rights activist, OONI Probe gives you the tools to see the truth behind your connection—and the power to do something about it.
