Show HN: Mousecrack – Bypass agent mouse detection with deep learning

Mousecrack, a deep-learning tool that synthesizes human-like mouse movements to bypass agent mouse detection, has been released as an open-source SDK and CLI under the MIT license. The project, currently at version 0.1.0, models mouse movement as a time forecasting problem using a Mixture Density Network to avoid mode collapse. Mousecrack is available for installation via npm and as plugins for Claude Code and Codex, though it remains experimental and for educational purposes only.

Synthesize organically varied, human-like mouse movement. This project aims to test the abilities of deep-learning for mouse imitation. demo.mp4 Clearly, it's not perfect. But this is v0.1.0. Still a lot of fun stuff to try on the model side : . npm i -g mousecrack Warning This project is still experimental For educational purposes only. Available as an SDK for developers and CLI for agents . js import { move, steps } from 'mousecrack'; await move 200, 400 ; // or alternatively... const from = { x: 100, y: 200 } const to = { x: 200, y: 400 } await steps from, to ; // // { x: 100, y: 200, t: 0 }, // { x: 95, y: 202, t: 10.528131778472712 }, // { x: 90, y: 210, t: 21.040190062833986 }, // { x: 81, y: 223, t: 31.892832399406224 }, // ... mousecrack move 200 400 x, y mousecrack steps 100 200 200 400 from x, y , to x, y Install the Skill For Claude Code: /plugin marketplace add puffinsoft/mousecrack /plugin install move-mouse@mousecrack For Codex: codex plugin marketplace add puffinsoft/mousecrack codex plugin add move-mouse@mousecrack Mousecrack treats mouse prediction like a time forecasting problem. It models mouse movement as a change in position dx, dy and time dt , and tries to predict the next step in this multivariate time series. To avoid the mode collapse https://en.wikipedia.org/wiki/Mode collapse problem, Mousecrack uses a Mixture Density Network to model several trajectories as a probability distribution.
