Clumsy 0.4 v2 is an open-source Windows utility that leverages the WinDivert library to simulate poor network conditions, such as lag, packet loss, and tampering, for testing and debugging purposes. The portable tool enables developers to evaluate application performance under unstable network environments by using filtering capabilities to intercept specific network traffic.
