About:
OONI Probe is a command-line tool designed to measure network interference and internet censorship. It runs a suite of network tests to detect tampering of web traffic, DNS manipulation, and blocking of websites and applications. This provides verifiable data to understand what networks are doing and how they affect users.
Key Features:
  • Runs standardized network tests (Web Connectivity, DNS Check, etc.)
  • Detects DNS manipulation, TCP/IP blocking, and HTTP censorship
  • Generates open data reports for transparency and research
  • Lightweight and scriptable for automated measurements
Use Cases:
  • Auditing network integrity and detecting ISP-level censorship
  • Researching internet freedom and network interference trends
  • Verifying website and service availability from different locations
Alternatives:
  • mtr – mtr is for network path diagnostics, while ooniprobe focuses on application-layer censorship detection.
  • traceroute – traceroute maps network hops, whereas ooniprobe tests for specific blocking behaviors and content manipulation.
