Free Windows tool that adds lag, packet loss and speed limits to one app, so you can test how it behaves on a bad connection. It adds latency, jitter, packet loss, corruption, duplication and bandwidth limits to the traffic of a chosen application, and reports every outcome as an exit code so it can run from a pipeline. It needs Administrator rights to capture traffic and asks for them itself. Profiles, window state and CSV exports are kept in %LOCALAPPDATA%\BeanNetworkTester, so upgrading the package leaves them alone.
