In their own words
GlassWire
GlassWire is a network traffic monitor and personal firewall for viewing network activity and controlling app connections. Its desktop traffic analysis breaks usage down by IP or host, app, traffic type, and other categories. Alerts flag unusual network or app changes that could indicate malware and unknown devices joining Wi-Fi. The Android app graphs app data use, alerts when apps access the network, and can block connections over mobile or Wi-Fi. GlassWire says Android app and data usage information stays on the phone and the app itself uses no data. The free tier limits network history to 24 hours, bandwidth usage history to one day, and alert logs to the current day. Premium provides unlimited network history, bandwidth history, and alert logs, along with bidirectional firewall controls, custom profiles, Ask to Connect, and Lockdown Mode. The Personal Plan costs $2.99 per month when billed annually. The desktop download requires Windows 10 or later and supports x64 and ARM64 architectures.
Sniffnet
Sniffnet is a free network monitoring app for Linux, macOS, and Windows. It displays overall internet traffic statistics and real-time charts, and can show which programs use bandwidth. Users can choose a network adapter, filter observed traffic, and import or export PCAP capture reports. Sniffnet identifies local network connections, shows remote hosts’ geographical locations, and finds host domain names and ASNs. It recognizes more than 6,000 upper-layer services, protocols, trojans, and worms. Users can configure notifications for network events and import custom IP blacklists to highlight potentially dangerous connections. The app supports live capture, display filters, protocol dissectors, and offline trace analysis; it reads PCAPNG and CAP files as well as PCAP. Custom themes and 26 languages are available. The listed Sniffnet plan is free and the software is open-source under MIT or Apache-2.0. A 2025 security audit reported one low-severity finding, which had been fixed. Most functionality uses offline databases, while reverse DNS lookups provide hostnames for IP addresses.
