OONI Probe vs CensorPulse

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?

CensorPulse shows how your network treats traffic. One tap runs a suite of on-device network probes and tells you, in plain language, whether a destination is reachable or something is interfering — and at which layer. What it checks • DNS: compares your system resolver with independent DNS-over-HTTPS resolvers to spot manipulated answers • TCP: whether a raw connection to the target completes, or times out / resets • TLS: whether a TLS handshake negotiates cleanly • SNI: whether interference is keyed on the TLS server name • App layer: whether a service itself refuses your region (HTTP 451) • Protocols: whether common internet protocols complete their handshakes on your network — measured against a test server we operate, so a failure points at the network, not at a site It probes a built-in set of well-known destinations — control sites, social networks, messengers, app stores, video calls, streaming, developer and AI services — and groups the results so patterns are obvious at a glance. Tap any result to expand the per-layer breakdown. Private by design • Measurements run from your device • Results are never uploaded • The protocol checks talk only to a test server we operate; it stores no payloads and keeps nothing about you after the run • Your IP address is not stored in the report • No accounts, no tracking, no ads Export any run as a JSON report and share it through the system share sheet — nothing is sent until you choose where. CensorPulse is a network tester — a measurement and diagnostics tool. It reports what it observes: it does not route or modify your traffic, does not connect you to any service, includes and recommends no tools, and does not provide access to any specific content.
