This is a list of notable Ajax frameworks, used for creating web applications with a dynamic link between the client and the server. Some of the frameworks are JavaScript compilers, for generating JavaScript and Ajax that runs in the web browser client; some are pure JavaScript libraries; others are server-side frameworks that typically rely on JavaScript libraries.


JavaScript frameworks are browser-side frameworks very commonly used in Ajax development. There are hundreds of JavaScript frameworks available. According to latest surveys,[1][2] the most used JavaScript frameworks are:

Framework License
axios, Promise-based HTTP client for the browser and Node.js MIT
jQuery, a JavaScript library that provides an Ajax framework and other utilities, and jQuery UI, a plug-in that provides abstractions for low-level interaction and animation, advanced effects and high-level, themeable widgets. GPL and MIT
MooTools, a compact and modular JavaScript framework best known for its visual effects and transitions.
Prototype, a JavaScript framework that provides Ajax and other utilities, and, a plug-in for animations and interface development. MIT
YUI Library, a set of utilities and controls, for building richly interactive web applications using techniques such as DOM scripting, DHTML and Ajax. BSD
ASP.NET AJAX, a set of extensions to ASP.NET for implementing Ajax functionality. Microsoft Public License
Spry framework, an open source Ajax framework developed by Adobe which is used in the construction of Rich Internet applications. It is no longer maintained.[3] MIT
Dojo Toolkit, an Open Source DHTML toolkit written in JavaScript. modified BSD license or the Academic Free License
Ext JS, a library that extends Prototype, Jquery and YUI until version 1.0. Since version 1.1 a standalone Ajax framework. GPLv3 or proprietary
Backbone.js, loosely based on the Model–View–Controller application design paradigm MIT[4]
AngularJS[5][6][7] MIT

Other notable frameworks that are more AJAX specific, and not among the list of general purpose frameworks:


These frameworks use Java for server-side Ajax operations:


The following frameworks are available for the Windows .NET platform:



A PHP Ajax framework is able to deal with database, search data, and build pages or parts of page and publish the page or return data to the XMLHttpRequest object.


These frameworks use Python for client-side Ajax operations:


The Ruby on Rails framework used to implement a Domain-specific language named RJS, which can be used to write Ruby code that generates Javascript code. The code generated by RJS was usually loaded using Ajax, e.g. by using Ajax-enabled helper methods Ruby on Rails provides, such as the link_to_remote helper. It was replaced by jQuery as of Rails 3.1[8]

Many of the Ruby on Rails Ajax-enabled helper methods used to work by using Prototype to perform an Ajax request in older versions of Rails. In most cases Javascript code is returned by the server to be executed by the browser, unlike the usual case where Ajax is used to retrieve data in XML or JSON format.[9]
