Intrexx. Intrexx is a cross-platform integrated development environment for the creation and operation of multilingual web-based applications, intranets, social intranets, enterprise portals and customer portals (extranets) as well as Industry 4.0 solutions as of 2018. A portal is created based on the drag and drop principle. Intrexx is a low-code development platform. Most applications can be created via drag & drop but manual coding can be added where necessary.

History 
The first version of the software was released by the German software vendor, United Planet, under the name "Intrazone" in 1999. In 2000, the software was renamed to "Intrexx Xtreme". With the release of Intrexx 5.0 in March 2010, the product line was divided into two editions: Intrexx Professional and Intrexx Compact. Intrexx Professional were the continuation of the Xtreme series and were still intended for SMEs and public administrations. Intrexx Compact contained a complete company portal with more than 50 ready-made web-applications and templates and is tailor-made for smaller companies with up to 10 PC workstations. United Planet stopped dividing the product line into two editions with the release of Intrexx 8.0. From this point on, it was simply called Intrexx. According to the manufacturer, there have been implemented more than 5,000 Intrexx portals to date (cited date: 2019). Between 2012 and 2014, the US IT research and advisory company Gartner Inc. placed United Planet with Intrexx in its market overview "Magic Quadrant for Horizontal Portals".

On the Steady Track, new features will be implemented directly after their completion in the course of regular software updates.

Architecture
Intrexx basically consists of two parts:

Intrexx Portal Manager

It is installed on any client or on the server and possesses all the components for developing and managing layout, menu or applications. Furthermore, users can be configured and provided with permissions for the respective portal applications in the Portal Manager.

Intrexx Portal Server

It is installed on a server and controls all transactions of the created web-based applications and portals. It monitors the permissions of the users within the transactions, controls the entire business logic operations and governs access to the data sources.

Functions
Intrexx provides companies with the ability to create and manage multilingual web-based applications, intranets, social intranets, enterprise portals and customer portals (extranets) as well as Industry 4.0 solutions as of 2018. In doing so, the software sees itself as an alternative to Microsoft SharePoint. Design and usability of the portal are provided by the integrated portal designer based on CSS and XML, enabling the adoption to the corporate identity of the company via XSLT transformations. Single sign-on guarantees a secure authentication and role-based authorization. The synchronization with existing LDAP-servers is possible.
