Greasy Fork

A community-driven repository of user scripts — small pieces of JavaScript that modify the appearance and behaviour of web pages — providing a safe and practical platform for discovering, installing, and sharing browser enhancement scripts. The site hosts tens of thousands of scripts created by developers worldwide, each designed to add features, remove annoyances, automate repetitive tasks, or improve the user interface of popular websites across social media, video platforms, search engines, e-commerce sites, and productivity tools. Users can browse scripts by target website, popularity, language, and creation date, with detailed descriptions, screenshots, and version history for each script. The platform emphasises safety by encouraging open-source licences, providing code review transparency, and flagging scripts that request sensitive permissions. A discussion section under each script allows users to report bugs, request features, and share feedback directly with script authors. Scripts are installed through compatible browser extensions such as Tampermonkey or Violentmonkey, which manage execution and updates automatically. The site supports script development through documentation, coding guidelines, and metadata standards that help authors create well-structured, maintainable scripts. Authors receive download statistics and feedback to understand the reach and impact of their work.
