Tessabyte

What Tessabyte is

Tessabyte measures wired and wireless network performance, including speed, packet loss, and jitter. It supports Wi-Fi speed tests, capacity tests, link quality analysis, stress tests, QoS assessment, and SLA verification across LAN, Wi-Fi, IPv4, IPv6, TCP, and UDP. Results chart uplink and downlink speeds, packet loss, and jitter; users can customize payloads and generate reports. The software uses client and server components, and multiple clients can connect to one server. The server component is free and can be installed on unlimited Windows, macOS, or Linux machines. The fully functional evaluation version lasts 30 days from first execution. Paid client licenses are one-time purchases: the 1-user license is $39, paid once, while 3-, 5-, 10-, and 25-user licenses are also listed. A Windows or macOS client user license allows installation on up to three personal machines, with one license required per user. Purchases include support and updates for one year; the license remains usable afterward, while upgrades are separate. Tessabyte is self-hosted and uses active testing.

Who it suits

Tessabyte suits professionals assessing wired or wireless network quality, capacity, or service levels. Its maker describes it as intended for professionals who have outgrown iPerf.
