About Znuny#


Znuny is the continuation of the OTRS Project created in 2001 by Martin Edenhofer. OTRS AG discontinued maintenance of the ((OTRS)) Community Edition in 2020. Martin’s company Znuny GmbH then forked the project to continue it under the name Znuny.

Since then the software has continued to grow, as never before, through contributions from many open-source support vendors and the hard work and financial backing from Znuny GmbH.


Znuny is used in a variety of ways. Some of the most popular are listed below:

  • Customer Service

  • Human Relations

  • IT Service Management

  • Facility Management

  • Association Management

Revision Security#

Znuny is audit-proof. The following features ensure this fact:

Revising core data is not possible for the user.

Core data is:

  • All communication and their attachments are unchangeable by the user.

  • All modifications to a ticket during the lifecycle are documented in the ticket history. * Who did what and when to the ticket.

A communication is:

  • any telephone notes

  • e-mails

  • internal notes

  • external notes

  • web service requests

  • or any other channel extended by an add-on.

The complete communication chain is documented, contains a timestamp, and is permanent for each request.

Each change of content’s history entry can be explicitly configured

This applies specifically, but not exclusively, to request attributes like:

  • user assignment

  • request title

  • assigned service

  • SLA agreement

  • configured dynamic fields

Deleting a request is a superuser task separately logged by the system.
