Score: 7.3/10 (Innovation: 6, Technical: 7, Documentation: 9, Utility: 7)

Snitch is a cross-platform, open-source network traffic visualizer that captures and displays every connection your computer makes in real time, with process attribution, geolocation, and anomaly detection. It stands out by combining live force-graph and world-map visualizations with offline geolocation and a strong privacy focus, all running locally without telemetry. The project is well-documented, actively maintained, and fills a gap between firewalls like Little Snitch and packet analyzers like Wireshark.

Target audience: security-conscious users, backend developers, devops engineers, privacy advocates
