The unobtrusive JavaScript framework for server-side web applications

Unpoly enables fast and flexible frontends while keeping rendering logic on the server. It has no dependencies and plays nice with existing code.

Smoother navigation

Unpoly links can update page fragments instead of full pages. No JavaScript required.

Branch off into layers

Branch off interactions into modals, popups or drawers. Return to the main page when you're done.

Animation

Animate page changes with fade, swipe or zoom transitions.

Faster response times

Outsmart latency by preloading pages, following links earlier, caching responses and keeping a persistent CSS / JS environment.

Structure for JavaScript snippets

Organize your frontend code in compilers and let Unpoly pair HTML elements with JavaScript behavior.

Better forms

Submit forms via AJAX. Work with forms within modals. Validate forms against server rules while filling in fields.

Plays nice with existing code

Migrate any server-side web application with minimal changes to existing code.

Extensible

Build your own components using Unpoly's extensive Javascript API and event model.

Degrades gracefully

Unpoly supports all modern browsers. On old IEs features are disabled gracefully.
