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