is a lightweight network simulation tool for Windows designed to degrade network conditions in a managed, interactive way. While the official open-source version is typically at version 0.3, a version labeled "0.4 Private tool v2" has appeared in online security sandboxes and gaming communities, often used as a software-based "lag switch". Core Functionality The tool leverages the

library to intercept live network packets. It captures specified packets based on filters (like inbound/outbound, TCP/UDP, or specific ports) and allows you to apply manual degradation before reinjecting them into the system. GitHub Pages documentation Detailed Features Lag Simulation

: Holds packets for a short, user-defined period to emulate high latency (ping). Packet Dropping : Randomly discards packets to simulate a lossy connection. Throttling

: Blocks traffic for a specific timeframe and then sends it in a single burst. Duplicate Packets

: Sends cloned packets immediately after the original to test for duplicate handling. Out of Order clumsy 04 v2 2021 download

: Rearranges the sequence of packets to simulate jitter or unstable routing.

: Modifies bits of the packet content to simulate corrupted data. Inbound/Outbound Filtering

: Allows users to apply these effects specifically to either data coming into the computer or data being sent out. Interactive Control

: You can start and stop the degradation at any time while your target application (like a game or web service) is still running. GitHub Pages documentation Key Specifications System Requirements

: Works on Windows only; typically requires Administrator privileges to run because it installs network drivers at runtime. Ease of Use

: No installation or proxy setup is required; it is a portable executable. Offline Support : Works even for localhost connections (127.0.0.1). GitHub Pages documentation for a particular game or application? Download - GitHub Pages

While Clumsy is a powerful tool, it acts as a proxy for your network traffic. Here are a few tips for safe usage: Whether you are a solo indie developer or
