Your internet traffic, under your control
Sniffnet is a powerful yet intuitive network monitoring tool, providing a polished dashboard of your Internet traffic. Sniffnet is cross-platform, completely free, and open-source — available for everyone to use without restrictions.
Sniffnet provides real-time network traffic monitoring with an intuitive GUI, allowing users to observe which programs generate traffic, view statistics, and inspect connections without requiring deep networking expertise. The cross-platform support (Windows, macOS, Linux) and 24-language availability make it accessible to diverse users.
Sniffnet allows import and export of comprehensive capture reports as PCAP files, enabling users to analyze traffic offline, share data with colleagues, or retain records for compliance purposes. Real-time filtering and search capabilities support detailed investigation of specific connections.
Sniffnet is developed in Rust for performance and safety, runs efficiently in the background (minimizable thumbnail mode), and provides persistent monitoring without requiring constant active attention. The lightweight architecture ensures reliable operation without significant CPU or memory impact.
Sniffnet v1.5 introduced application identification to show which programs use network bandwidth. Users can see program-level traffic statistics, save favorite programs, and set notifications when specific applications generate network activity.
Sniffnet identifies 6000+ upper-layer services, protocols, trojans, and worms; discovers geographical locations of remote hosts; supports custom IP blacklists; and enables custom notifications for defined network events. Security audits confirm its safety-first design protects user data privacy and system integrity.
