## What it is
Prepros is a commercial cross-platform desktop GUI app that compiles Sass, Less, Stylus, Pug, TypeScript and other preprocessing languages, bundles JavaScript, and provides a built-in server with automatic browser reload. The GitHub repository only contains archived old code; development continues on the closed-source product at prepros.io.

## Use cases
- compile sass and less files automatically
- live reload browser while developing websites
- bundle es6 javascript modules without config
- preview local site on mobile devices
- minify css and javascript assets
- test website across multiple synced devices

## When to choose
- you want a GUI alternative to build tooling like Gulp or Webpack for preprocessing
- you need zero-config compilation, bundling, and live reload in one desktop app
- you work across Windows, macOS, and Linux

## When to avoid
- you need a free open-source tool - the maintained product is paid and closed-source
- you want to extend or contribute to the code - the repo is archived and outdated
- you prefer CLI-based or scriptable build pipelines
