Infuse

Edit any page's CSS/JS live from an external app

Infuse lets you customize web pages in your browser using a companion editor. Connect the extension to the editor with a pairing code, select an open page, and manage your changes from one place. Features: • Apply custom CSS and JavaScript. • Inspect elements through a DOM preview. • Save separate rules for different websites. • Enable, disable, or delete saved rules. • Keep saved modifications active after disconnecting from the editor and refreshing the page. • Restore saved editing fields when reconnecting. How to get started: 1. Use Chrome 138 or newer. 2. To run your own JavaScript, open chrome://extensions, choose Infuse > Details, and enable Allow User Scripts. CSS and text replacements work without this setting. 3. Open https://infuse.infuse-asfeagle0304.workers.dev 4. Copy the pairing code displayed by the editor. 5. On the webpage you want to edit, open Infuse and connect using that code. 6. Select a page in the editor and start editing. The companion editor communicates with the extension through a hosted relay service. Saved rules are stored locally in the extension. Infuse is under active development. Some browser-protected pages cannot be modified.
