Professional network testing
Free · In‑App Purchases
Professional Wi-Fi network performance testing tool. Measure TCP/UDP throughput, jitter, packet loss. Run stress & load tests, find bottlenecks, optimize connectivity.
Experience the difference with Tessabyte — a powerful tool for measuring and analyzing network performance. This utility sends TCP and UDP data streams across your network and computes important metrics such as upstream and downstream throughput, packet loss, jitter, and round-trip time, and displays the results in both numeric and chart formats. Whether you're troubleshooting connectivity issues, validating upgrades, or optimizing your network, Tessabyte provides precise insights into its speed and reliability.
Tessabyte uses a client-server setup to run tests, so a server component (which can be downloaded at https://www.netmantics.com) is highly recommended for local network testing. However, the application also offers access to public test servers.
What can you do with Tessabyte?
