GeoExt 3 — JavaScript Toolkit for Rich Web Mapping Applications
GeoExt is Open Source and enables building desktop-like GIS applications through the web. It is a JavaScript framework that combines the GIS functionality of OpenLayers with the user interface of the ExtJS library provided by Sencha.
Version 3 of GeoExt is the successor to the GeoExt 2-series and is built atop the following official installments of it's base libraries; OpenLayers 4.6.5 and ExtJS 6.2.0. The versions of GeoExt that support these libraries are version 3.3.2 and the older version 3.2.0.
GeoExt is an OSGeo Community project - a member of the Open Source Geospatial Foundation (OSGeo) family of projects. Everybody is invited to help us create the next version of GeoExt.
Since version 3, GeoExt is based upon Ext JS 6.2.0.
This means GeoExt can be used just like any other Ext component, and applications making use of GeoExt also profit from Ext JS enhancements like charting, a harmonized API with Sencha Touch and a sophisticated single-file build tool.
GeoExt 3 is a rather young project, a lot of the code and structural decisions come from a code sprint in Bonn. 9 developers gathered there from 2015-06-17 to 2015-06-19. We are deeply grateful that our sponsors helped to start GeoExt 3.
Now, have a look at the examples below, read the API documentation, the API documentation (including ExtJS classes) or checkout the code
There are multiple ways to download and use GeoExt.

The following table lists the versions of OpenLayers and ExtJS that the respective version of GeoExt is compatible with:
| OpenLayers | ExtJS | GeoExt | status |
|---|---|---|---|
| > 4 | 6.2.0 | master | work in progress |
| 4.6.5 | 6.2.0 | 3.3.2 | released |
| 4.3.3 | 6.2.0 | 3.2.0 | released |
| 4.3.3 | 6.2.0 | 3.1.0 | released |
| 3.20.1 | 6.2.0 | 3.0.0 | released |
| 2.13.1 | 5.1.0 / 4.2.1 | 2.1.x | released |
| 2.11.1 | 3.4.0 | 1.1.x | released |
Of course you can still use GeoExt 1.x or GeoExt 2.x, but these libraries do not receive much attention these days.
