Sustainable Browser Extension - Reduce Your Carbon Footprint While Browsing

The Sustainable Browser Extension helps make the web more sustainable by intercepting CDN requests and serving popular JavaScript libraries from local storage instead of downloading them repeatedly from remote servers.

KEY FEATURES

Eco-Friendly Browsing
• Reduces redundant network requests to CDNs
• Lowers bandwidth consumption and carbon emissions
• Faster page load times by serving files locally

Smart Dependency Management
• Pre-downloads popular libraries and their dependencies
• Automatically handles version compatibility and peer dependencies
• Seamlessly redirects esm.sh CDN requests to local files

Zero Configuration
• Works automatically once installed
• No setup required
• Compatible with all websites using esm.sh CDN

Privacy-Focused
• All dependencies served locally
• No tracking or data collection
• Open source and transparent

HOW IT WORKS

The extension maintains a local cache of popular JavaScript libraries and their dependencies. When a website tries to load a library from esm.sh CDN, the extension intercepts the request and serves the file from local storage instead. This reduces network traffic, speeds up page loads, and decreases the environmental impact of web browsing.

CURRENTLY SUPPORTED LIBRARIES

• React (versions 18.x and 19.x)
• Vue.js
• Framer Motion
• Lucide React
• Tailwind-merge

COMING SOON

We're actively working to add support for major web libraries, frameworks, and design systems including:
• Angular
• Svelte
• Material-UI
• Tailwind CSS
• And many more popular packages

TECHNICAL DETAILS

• Uses Chrome's declarativeNetRequest API for efficient request interception
• Handles complex dependency trees and peer dependencies
• Maintains version compatibility across related packages
• Supports both wrapper files and implementation files
