What is EXt JS 5?

A Better Way to Build Business Apps

With over 1000 documented APIs, a rich data package, and a class-based architecture , Ext JS 5 is the leading standard for building business-centric apps.

Modern App Framework

Ext JS 5 is the industry’s most powerful application development platform for delivering solutions to the most platforms, devices from legacy browsers on the desktop, as well as tablets and touch-based devices.

Robust User Interface Library

With more than 150 user interface components all designed to work together, Ext JS 5 delivers the most complete set of tools for solving business app challenges.

Why EXT JS 5 ?


Things that normally take hundreds of lines of code can be done in minutes using pre-built components.


Whether your app requirements change or your team grows, Ext JS is engineered to scale as your needs change and evolve.


Build your business apps with confidence and peace of mind knowing there are more than 2 Million Ext JS developers worldwide and an active community.


It’s a multi-device, multi-platform world. Ext JS 5 is architected to build apps that will work on legacy browsers as well as the latest touch-based devices.

“One framework, multiple form factors and devices, including desktop and mobile — that’s the promise of Ext JS 5. We build our app once, and our developers move quickly and easily onto new projects.”
Chris Thornhill, Chief Architect at Aptean

“We upgraded to Ext JS 5 because it helped our dev team become significantly more efficient. With MVVM, Ext JS 5 delivers a modern architecture on top of unrivaled, high quality, proven component and data packages.”
Rouslan Zenetl, Director of Application Development, National Hockey League

“Ext JS 5 will give us big productivity gains. Having one code base with support for a wide variety of modern and legacy browsers reduces our testing burden and frees up more time to implement the features our customers want most.”
Diana Jaffe, Product Manager, Guidewire

“The migration path from Ext JS 4 to Ext JS 5 is extremely minimal, so developers can upgrade apps with less effort and take advantage of the new features quickly.”
Jay Garcia, Co-founder and CTO of Modus Create

“We converted one of our apps to Ext JS 5, and it was quite simple. If you have a well-structured Ext JS 4 app, the conversion to Ext JS 5 should be a snap.”
Richard Milone, Managing Partner at CNX Corporation

“Sencha has made the Ext JS 4 to Ext JS 5 upgrade path nearly seamless. It will be easier to maintain apps in Ext JS 5 because the MVVM architecture makes collaboration between our developers more efficient.”
Steve Drucker, Founder and President, Fig Leaf Software
