What is Tampermonkey?

Enhance your browsing experience with custom scripts

Browser Extension

Tampermonkey is a free browser extension available for Chrome, Firefox, Safari, Edge, and Opera that lets you run custom JavaScript code (UserScripts) on any website.

Customize Websites

UserScripts can modify webpage behavior, add new features, automate tasks, improve UI/UX, and integrate with external APIs - all without changing the original website.

Safe & Controlled

Scripts run in a sandboxed environment with explicit permissions. You control which scripts run on which sites. Scripts are stored locally and can be enabled/disabled anytime.
