An open platform instead of commercial product configuration
Today’s OTRS is procured through licensed users, a base, extras and service packages. Qisutu can be freely downloaded, inspected, adapted and self-hosted under the AGPL.
Qisutu gives organisations control over software, data, extensions and operating model.Why Qisutu?
Why Qisutu is the stronger new choice over OTRS
Qisutu combines capabilities that would otherwise have to be distributed across different systems, add-on products or individual integrations.
Full technical control
Organisations decide their infrastructure, data storage, adaptations, updates and extensions.
Ten open specialist modules
The new add-on portfolio extends Qisutu with complete ITSM, five Kim capabilities, Microsoft 365, Entra ID and monitoring.
The Qisutu difference
What Qisutu does differently from OTRS
This comparison highlights where Qisutu takes its own broader approach through a new architecture and ten coordinated add-ons.
| Criterion | Qisutu | Difference from OTRS |
|---|---|---|
| Product model | Freely available independent open-source platform. |
Today’s OTRS is a commercially configured vendor offering and is not the discontinued Community Edition. |
| Licensing | AGPL-3.0-or-later; no user-based software licence for self-hosting. |
The offer is assembled through licensed users, a base, extras and services. |
| Source and control | Public source code for the core and reviewed Qisutu add-ons; self-hosting and custom adaptations are possible. |
Use and scope are governed by the procured OTRS offer and its terms. |
| ITSM and CMDB | CMDB in the core; ITSM Enterprise connects Incident, Major Incident, Problem, Known Error, Change, Release, CAB and reviews. |
The exact OTRS ITSM and CMDB scope depends on the base, extras and offer. |
| AI | Five independent Kim add-ons for product help, automatic replies, routing, processes and knowledge development. |
AI capabilities must be checked against the current OTRS version and selected extras in the offer. |
| Microsoft 365 and Entra ID | SSO for agents and contacts plus calendar, Teams, meetings, SharePoint and semantic document search directly in Qisutu. |
Required integration scope must be covered and offered through OTRS features, web services or extras. |
| Monitoring | Seven ready-made integration paths for external monitoring events, including correlation and recovery. |
An equivalent OTRS integration depends on the specific feature and integration scope procured. |
| Cost structure | Software is freely available; only optional services such as hosting, implementation, migration, support or development are paid. |
Commercial product and service package with quotation-dependent terms. |
The Qisutu profile
What Qisutu brings as a new platform
Qisutu combines its newly developed core with ten independent add-ons. The system can therefore grow step by step from ticketing into a broad service workspace.
Independent new development
Qisutu is not a fork of OTRS, OTOBO, Znuny or Zammad. Its architecture, interface and add-on API were built from scratch.
Ten modular add-ons
ITSM Enterprise, Monitoring, Microsoft 365, two Entra ID modules and five specialised Kim extensions can be added selectively.
Kim in several roles
Product help, automatic customer replies, business-aware routing, process creation and knowledge development are separate and controllable capabilities.
Microsoft 365 in the service desk
Personal calendars, Teams, meetings, SharePoint files and semantic document search are available directly in the agent interface.
Coherent ITSM domain model
Incident, Major Incident, Problem, Known Error, Change, Release, CAB and Post-Incident Review use tickets, services, SLAs and the CMDB.
Monitoring becomes ticket work
Events from Checkmk, Zabbix, Icinga 2, Nagios, PRTG and Prometheus are authenticated, correlated and followed through to recovery.
The Qisutu advantage
Why choose Qisutu instead of OTRS now?
Qisutu was not created as a copy of OTRS. The platform was newly developed to connect ticketing with today’s ITSM, AI, Microsoft 365 and monitoring requirements.
No licensing by user countQisutu self-hosting is not tied to a number of licensed agents.
No dependency on a selected vendor packageQisutu features and source code can be inspected directly and self-hosted.
Open extensions instead of quotation-specific extrasTen Qisutu add-ons extend the platform under open licences.
Operation by your own decisionOwn infrastructure and professional hosting are possible without giving up software sovereignty.
