Violentmonkey

Violentmonkey

An open source userscript manager.

Violentmonkey provides userscripts support for browsers.

NOTE

This extension does not contain any ads and does not modify web pages automatically. Any changes and modifications on the sites are done by installed scripts. Therefore, please install only scripts that you trust.

WARNING

This extension is no longer supported on Chrome due to its Manifest V2 architecture. While a Manifest V3 rewrite might be considered in the future, it is not planned for the foreseeable future due to the considerable effort involved and the potential for losing existing features.

As an alternative, consider using Brave browser which is also open source, where you can install it from the Chrome Web Store.

Violentmonkey is built with web extension APIs, thus supports many browsers.
