Mutahunter – Fast, language agnostic, software testing using LLM agents

In plain words

Mutahunter is a software testing tool that uses AI agents to automatically test code across multiple programming languages. It applies mutation testing—a technique that deliberately introduces small changes to code to verify that tests catch them—powered by large language models. Designed for developers and QA teams, it streamlines the testing process by working language-agnostically, allowing teams to validate their test suite effectiveness without manual configuration for each language.

  I created an After Effects alternative▲1,150

  Many years ago, I made VJ softwares (to mix live visuals in clubs) for unexpected platforms like the Game Boy Advance, the Playstation 2 and the Raspberry Pi. This year, I’m back with a new web-app: Pikimov. Inspired by Photopea (a free Photoshop clone), I created this web-based motion design & video editor as an alternative to After Effects, to fill empty void. It's free, without signup, without cloud uploads (your files stay on your machine), and your projects are not used for AI models training.
