PagePatch — Custom CSS & JS

Inject custom CSS and user scripts into pages that match your URL rules.

PagePatch is a user-controlled webpage customization tool. It applies custom CSS styles and user scripts only to URLs explicitly configured by the user. Users can adjust page layouts, improve readability, hide distracting elements, add personal interface enhancements, or automate small repetitive interactions on websites they use regularly. PagePatch supports inline CSS and JavaScript as well as linked CSS and JavaScript resources. Each rule can be enabled or disabled independently. Rules and preferences are stored locally in the browser, and site access is requested only for domains configured by the user. Users should install PagePatch if they want persistent, reusable webpage customizations without manually opening Developer Tools or running code again on every visit.
