Tessabyte is a network performance testing software that measures throughput, jitter, and speed across Wi-Fi, LAN, and WAN environments. It is designed for engineers and IT professionals who need more than just a quick speed check.
With Tessabyte you can run TCP and UDP tests, apply QoS tags, and generate custom payloads to simulate realistic network traffic. Results are shown in detailed, exportable reports, helping you track performance over time or share findings with colleagues. The software also includes scheduling, making it easy to automate recurring tests without manual setup.
Unlike command-line tools such as iPerf3, Tessabyte comes with an easy-to-use graphical interface. This makes it accessible to new users, while still offering the flexibility advanced users expect. You can configure test duration, payload size, and protocol options directly from the interface, without writing scripts or memorizing commands.
Tessabyte is cross-platform, running on Windows, macOS, and Linux, with upcoming support for Android and iOS. This allows you to test between different types of devices and operating systems, ensuring a consistent view of network performance across your environment.
Key use cases include validating Wi-Fi coverage, benchmarking LAN or WAN links, stress testing under load, and verifying QoS policies. Tessabyte is suitable for enterprise IT teams, network consultants, educators, and anyone who needs accurate performance data rather than consumer-level test results.
By combining ease of use with advanced testing features, Tessabyte makes professional network testing accessible without sacrificing depth. It is a practical tool for anyone who needs reliable insights into network capacity and quality.

Tessabyte's answer:
Tessabyte is unusual because it combines broad platform support with multiple ways to run the same tests. It works on Windows, macOS, iOS/iPadOS, and Linux, so engineers can test real networks using the devices they actually have. It also supports both a graphical interface and command-line operation, making it practical for quick manual checks, repeatable testing, automation, and more advanced troubleshooting workflows.
Tessabyte's answer:
Choose Tessabyte if you want network testing that feels like a finished professional product, not a collection of scripts. It gives you clear results, repeatable tests, useful reports, and diagnostics that are easy to share with colleagues, customers, or vendors. Tessabyte is designed to make serious throughput testing practical in everyday work: less guesswork, less setup friction, and better evidence when something on the network is not performing as expected.
Tessabyte's answer:
Tessabyte is primarily built for network engineers, IT administrators, Wi-Fi professionals, system integrators, and technical support teams who need to measure real network performance. Its users are people who troubleshoot LAN, WLAN, and WAN environments, validate installations, investigate customer complaints, or document performance before and after network changes.
