clumsy is a Windows utility that degrades network conditions in a controlled, interactive way by capturing live packets with WinDivert and applying lag, drop, throttle, duplicate, reorder, or tamper effects. It requires no installation, proxy setup, or code changes and works system-wide on any TCP/IP application.
Use cases
- simulate network latency and packet loss on windows
- test app behavior on poor or flaky connections
- debug bugs caused by broken network conditions
- emulate lag for localhost or offline testing
- throttle or duplicate packets to stress-test network code
When to choose
- you need to simulate bad network conditions on Windows without changing your app or setting up a proxy
- you want interactive, on-the-fly control of packet lag, drop, throttle, duplicate, reorder, or tamper
- you need system-wide packet manipulation that works on any TCP/IP application, including localhost
When to avoid
- you are on Linux or macOS - clumsy is Windows-only
- you need scripted or automated network fault injection rather than interactive GUI control
- you need bandwidth shaping or traffic prioritization rather than packet-level degradation
