About

Experimentation Local Interface (ELI) is a powerful Chrome extension for developers who need to create, test, and iterate on web experiments quickly.

   KEY FEATURES:
   • Flexible project organization - Configure your projects directory anywhere on your system
   • Variant system - Organize experiments with variant folders (v1, v2, etc.)
   • Import system - Import HTML, SCSS, and JS files directly in your code
   • Hot reloading - Changes to your scripts are reflected immediately
   • Easy injection - Select a project and variant from the extension popup
   • Auto-inject - Optionally auto-inject your selected variant on every page load
   • Auto-minification - Minified files are automatically generated on save

   PERFECT FOR:
   • A/B testing developers
   • Web experiment creators
   • Frontend developers testing UI changes
   • Teams working on web experiments

   HOW IT WORKS:
   1. Start the local development server (included)
   2. Organize your experiments in project folders with variants
   3. Select a project and variant from the extension popup
   4. Inject your experiment into any web page instantly
   5. Make changes and see them reflected immediately with hot reloading

   The extension communicates only with your local development server (localhost:8000) and never transmits any data externally. All preferences are stored locally in your browser.
