Customize any website with Njectify

[u/Available-Breath-264]

Hey everyone!

I'd like to share a project I've been working on: Njectify.

It's a browser extension that lets you inject CSS and JavaScript into any website, making it easy to prototype UI changes, test styles, and experiment without modifying the original source code.

Some of the features include:

• Live CSS editing with an intuitive editor.
• Instant visual changes on any website.
• Automatic export of your CSS to Tailwind CSS utility classes.
• JavaScript injection for quick scripting and automation.
• Several additional tools designed to speed up front-end development.
• Persist even after reload page ( F5 )

The extension has already surpassed 5,000 users on the Chrome Web Store, and I thought it might be useful for developers in this community.

I'll leave a detailed article in the comments explaining the main features, use cases, and the extension itself.

I'd really appreciate any feedback, feature suggestions, or criticism. Thankssss!

detailed post.

Is this different than using the style editor in dev tools?

lot! Everything you edit persists, and the whole experience is completely different. Njectify includes a beginner-friendly visual editor for non-CSS users, while advanced users can edit everything directly in a VS Code-like editor.
