Parcel

Parcel is the zero-configuration web bundler trusted by developers at companies like Facebook, Microsoft, and Atlassian for its simplicity and performance. With over 1 million weekly downloads, it eliminates the complex setup that traditional bundlers require while delivering exceptional build speeds through multi-core processing.

What makes Parcel exceptional is its intelligent automation - it automatically detects and transforms TypeScript, SASS, PostCSS, and images without any configuration files. This “works out of the box” philosophy lets developers focus on building features instead of configuring build tools.

Frontend developers choose Parcel because it removes the friction from modern web development. From rapid prototyping to production applications, it provides the fast, reliable bundling that teams need without the configuration overhead that slows down development.
