What is swup?

Swup is a versatile and extensible page transition library for server-rendered websites. It manages the complete page load lifecycle and smoothly animates between the current and next page. In addition, it offers many other quality-of-life improvements like caching, smart preloading, native browser history and enhanced accessibility.

Make your site feel like a snappy single-page app — without any of the complexity.
