Clumsy is a lightweight, portable application for Windows (Vista and above) that leverages the library to capture, manipulate, and reinject network packets in real-time. Unlike traditional proxies that require complex configurations, Clumsy works system-wide, affecting any application without needing code changes.
Here’s a solid, release-style write-up for , written as if for a changelog, GitHub release, or dev diary.
If you are a backend developer, a QA tester, or a gamer looking to simulate lag, remains one of the most useful, lightweight, and reliable tools in the Windows ecosystem. It effectively answers the question: "How does my application behave when the network turns terrible?" clumsy 0.4 v2
Clumsy 0.4 v2: The Ultimate Network Simulation Tool for Windows
One of Clumsy's greatest strengths is its simplicity. Because it is portable, . Download - GitHub Pages Clumsy is a lightweight, portable application for Windows
WinDivert library, it captures live network packets and allows you to apply various "deterioration" effects on demand. Core Features of Clumsy 0.4 v2 Lag Simulation: Holds packets for a specific duration to emulate high latency. Packet Dropping: Randomly discards packets to simulate a lossy connection. Throttling: Blocks traffic for a set timeframe and then releases it in a single batch. Tampering: Alters small bits of packet content to test for data corruption handling. Out of Order & Duplication: Rearranges the sequence of packets or sends clones of original packets. Common Use Cases Software Development: Developers use it to find bugs related to unstable networks or to see how a web app performs on slow 3G-style connections. Game Testing: It is frequently used to test multiplayer game performance under heavy lag. Experimental Exploitation: Some users in gaming communities have used the tool to create "lag switches" to gain advantages in competitive shooters or to force solo lobbies in online games. How It Works 10 sites clumsy 0.3 - GitHub Pages clumsy will choose which packets to capture by given filter, in which in can specify whether it's inbound or outbound, tcp or udp, GitHub Pages documentation clumsy makes your network condition on Windows ... - GitHub Oct 21, 2023 —
If you still fly into orbit, that’s not a bug. That’s dramatic clumsiness . If you are a backend developer, a QA
Introduces a specific delay (in milliseconds) to packets. This is essential for testing how applications handle high-latency environments.
clumsy 0.4 v2 is a masterpiece of "do one thing and do it well." It turns hours of network debugging work into a simple toggle switch. If you develop software that touches the internet, this tool belongs in your utility belt.
Re-arranges the sequence of packets, a common occurrence in complex routing paths that can break poorly implemented protocols.
Default profiles changed slightly — existing projects will retain old values unless you reset to new defaults.
