Wikipedia:Zammad

Zammad is a free helpdesk or issue tracking system. It offers the connection of various channels like email, chat, telephone, Twitter, or Facebook. Zammad is developed in the programming languages Ruby and JavaScript. The name Zammad comes from the Bavarian dialect and means "together".

General
Zammad was founded by Martin Edenhofer, who was formerly involved in the development of OTRS.

The project asks for active participation in the development. The source code is open-source according to the GNU AFFERO General Public License (GNU AGPLv3) License and available via git. For this purpose, the Zammad Foundation was founded to ensure the freedom of the software. Inspiration for the Zammad Foundation are WordPress, Free software, and the Mozilla Foundation.

User Interface
The user interface is modern and attractive. It has been redesigned from scratch and can be used by occasional users without training without any problems. Technologically, the user interface is implemented as a Web application with CSS, JavaScript, and HTML5 (including WebSockets), which means that the application runs in the browser - only data is exchanged over the network (in REST). Thus the WebApp feels like a native application and is capable of real-time (information is updated in all clients immediately after creation/change without reloading the application/web page). The design of the interface was developed with Zeughaus Design GmbH.

In version 3.0 Zammad was extended by a Knowledge base.

Backend
The backend is realized in Ruby on Rails and communicates with the user interface via REST. Zammad relies on Elasticsearch to speed up search queries.

MySQL, MariaDB, or PostgreSQL are supported as database servers. Nginx or Apache can be used as a Web server or Reverse proxy.

Version history
The planned release cycle was 4 weeks, on the 14th of the month.
