LANSpeed measures the real performance of your local network—not your ISP. It automatically discovers nearby devices, then tests upload, download, latency, jitter, and packet loss with a native Rust engine. No cloud, no iperf3, and no external test servers. Run it on Windows, macOS, Android, or an always-on Docker/NAS/OpenWRT daemon, with live charts, history, diagnostics, parallel streams, and CSV export.
