Tessabyte
Tessabyte measures network performance on wired and wireless connections, charting uplink and downlink speed, packet loss, and jitter.
What Tessabyte is
Tessabyte measures network performance on wired and wireless connections, charting uplink and downlink speed, packet loss, and jitter. It supports Wi-Fi and LAN tests over IPv4, IPv6, TCP, and UDP, with uses that include capacity checks, link-quality analysis, stress testing, QoS assessment, and SLA verification. Payloads can be customized, and results can be turned into reports. The software uses client and server components, with multiple clients able to connect to one server. Its server component is free and can be installed on unlimited Windows, macOS, or Linux machines. A fully functional evaluation lasts 30 days from first execution. Paid client licenses are one-time purchases: the 1-user license costs $39, paid once, and permits installation on up to three personal Windows or macOS machines; one license is required per user. Purchases include technical support and software updates for one year. After that, the license remains usable, while upgrades are separate. The maker describes Tessabyte as intended for professionals who have outgrown iPerf.
