Userscript manager for Manifest V3
Script Monkey Next is a userscript manager for Chrome MV3. Write scripts in the built-in editor, manage URL matches, and run custom logic on the sites you choose via the modern userScripts API.
Create, edit, and run custom scripts on the sites you choose through the official Chrome userScripts API — the supported path for user-provided code under MV3.
Supports @match, @include, @exclude, @run-at, @name, @description, and @version so scripts feel familiar if you are coming from classic userscript managers.
Write JavaScript in a full dashboard editor with syntax highlighting. The popup lists scripts for quick enable/disable; the editor is where you do deeper work.
Run scripts in the USER_SCRIPT world for isolation, or MAIN when you need to touch page globals. Choose the world that matches the job.
Toggle individual scripts or pause the entire engine without deleting anything. Settings and scripts stay in local chrome.storage.
Light, dark, or system theme across popup, options, and the editor so late-night scripting stays comfortable.
