LANSpeed

LANSpeed measures upload and download throughput, latency and jitter between devices on your local network, rather than testing your internet provider. Discover peers automatically or connect directly by IP, view real-time charts, and save local test history with CSV export. Available for Windows, macOS, Linux and Android, with a Docker/NAS server endpoint. A second compatible device or LANSpeed server is required. Pricing varies by platform; desktop store editions offer a trial and a one-time purchase.
