bwmon vs GlassWire

bwmon is a free, self-hosted bandwidth monitor for one Linux host and one network interface. Its dashboard updates receive and transmit rates every second, charts recent traffic, and lists top processes. When traffic passes five times its rolling two-minute average, bwmon records process attribution, all-interface rates, and leading conntrack flows for spike investigation. It retains five-minute samples for six months, with views from one hour to all time, a time-of-week heatmap, and a rate histogram. A banner appears when the rolling five-minute average reaches 40 Mbps; cleared alerts remain in the history table. Installation uses a shell script that sets up the collector, systemd service, cron jobs, and nginx server block; the dashboard defaults to port 8080. It requires Linux kernel 4.0 or later and root access. Debian and Ubuntu use the apt-based installer, while other distributions need manual dependency setup. The project recommends authentication for internet-exposed installations.

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.
