GreaseKit: Open-Source Browser Extension Framework

Build browser extensions for Google Chrome and Firefox using standard web technologies like HTML, CSS, and JavaScript with GreaseKit, an open-source framework.

What is GreaseKit?

GreaseKit is an open-source browser extension framework for Google Chrome and Firefox. It allows developers to build powerful browser extensions using standard web technologies like HTML, CSS, and JavaScript.

One of the key benefits of GreaseKit is that it abstracts away much of the underlying browser extension APIs, making development faster and easier compared to building extensions from scratch. For example, GreaseKit handles cross-browser compatibility issues, provides common utilities like storage and messaging, and offers a simple framework to modularize extension code.

Some example uses of GreaseKit include building productivity enhancements like custom sidebar panels, developing developer tools extensions like custom inspectors or validators, and creating niche customizations for specific sites or workflows. It can also serve as the foundation for more complex extension projects.

While GreaseKit reduces much boilerplate code compared to native browser extensions, it still provides direct access to underlying browser APIs for advanced customization. Developers with existing web development skills can leverage them to unlock the extensibility of their browsers.
