What People Are Saying

I have been using it quite substantially for a number of different projects now and must say that I absolutely love the way it works.

I've been using your grid on a couple of small projects and I've got to say it's an awesome piece of work. It's very easy to configure and offers a lot of features while staying really responsive. As a programmer it inspires me to write better code.

- Collanders
I must say, I really like all of these controls. They have clean, elegant visuals and the attention to design detail really makes me a fan. In particular, the grid is just incredible.

I was searching for a slick and simple, but also user-friendly UI library. I tried Polymer, Angular, OpenUI5, jqwidget, … but they do not satisfy my needs. I don’t want to declare the whole UI in html (templates) but instead will create ALL UI elements programmatically (in an easy way). With w2ui this can be done really easy and the UI elements looks really nice.

- Gerald Leeb
W2UI is an excellent library! In less than a couple of days I was able to reach the same degree of functionality in my project (an interface for my lab database), which took me a couple of months using a well known widget library. W2UI is clean, small, fast and efficient. Plus, it's good looking!

- Antonio Santos
Very nice looking library. I'm impressed and very hopeful that this will continue to grow and become a major player. The Grid is awesome!

- John Whitten
I'm loving w2ui, it packs a lot of punch for such a light library. After working with ExtJS for 5 years, I've finally found a suitable replacement. The grid is fantastic! Thanks for all your hard work.

- Neil Grover
I am seriously blown away at the amazing quality of this library. Well done!

- Billy
This is amazing! If any project I use this is profitable I'll make sure to pay you for it.

- Bruno Cassol
This is incredible, thank you.

- Anthony Isaacson
This library is absolutely amazing, i never seen in my life such a clean and understandable code!!! Congrats for your work!

- MrCatt
First of all, thank you very much for your hard work on these components - they're all very, very good!

Only 97kb

Complete w2ui (v1.5.x) library is under 100kb (minified and gziped) and provides extremely fast load and execution. It is 9 times smaller than ExtJs and 7 times smaller than Kendo IO. No other UI library comes even close.

Declarative Syntax

Use JSON configuration to define elements of the UI. Very expressive syntax and easy to resuse, and it provides clear separation between data and logic layer of your application.

All In One

Out of the box w2ui is an all-in-one solution. It contains common UI widgets: Grid, Forms, Toolbars, Layout, Sidebar, Tabs, Popup and various field controls. You do not need to put together a collection of mismatched plugins to accomplish your goals.

Superior UX

Pixel perfect design, modern look and feel and complete JavaScript transparency are the key factors of w2ui library. Check out our demo page to see it in action.

Modern Browsers

The library heavily uses HTML5 and CSS3 and yet supports all major modern browsers. Latest Chrome, FireFox 7+, Safari 5+ and IE 9+ and Latest Edge are all supported browsers.
