Violentmonkey is an open-source userscript manager implemented as a browser extension built on WebExtensions APIs. It lets users install and run custom JavaScript scripts to customize web pages and automate tasks across Chrome, Firefox, Edge, and other compatible browsers.
Use cases
- run userscripts in my browser
- customize how websites look and behave
- automate repetitive tasks on web pages
- greasemonkey alternative for chrome
- sync userscripts across browsers and devices
- manage and edit userscripts with an external editor
When to choose
- you want a free, open-source userscript manager with no ads
- you need cross-browser support via WebExtensions including Manifest V3 Chrome
- you want script syncing to Dropbox, OneDrive, Google Drive, or WebDAV
When to avoid
- you need to modify browser behavior beyond web page content
- you want a fully sandboxed extension that never alters pages - installed scripts do modify sites
- you need extension support for browsers without WebExtensions APIs
