Znuny

Znuny is an open-source ticket and service-management platform for help desks, ITSM, customer support, and other service operations. It is strongest for organizations that need to tailor workflows and can manage a self-hosted system or arrange hosting and support. The free core is a meaningful advantage; its breadth also brings operational responsibility.

Overview

Teams can run Znuny on their own server or have it hosted by Znuny. That choice accommodates organizations with infrastructure of their own as well as those that prefer a hosted arrangement, while paid support offers a route to help with setup and ongoing operation.

The platform’s scope extends beyond ticket intake: it combines multiple request channels, automation, knowledge and self-service tools, and service-management capabilities. Its open-source code and extensive configuration options make it adaptable, but organizations seeking a narrowly scoped, ready-made workflow may have less reason to take on that flexibility.

Key features

Requests can arrive through a customer self-service portal, email, phone with CTI, REST and SOAP web services, and monitoring tools. This range suits service desks that need to connect channels and systems beyond email. Routing, classification, escalation, notifications, and state management can be automated, helping teams define how work moves through their operation.

Knowledge management and self-service let customers look for answers themselves. SLA management, approval workflows, an employee portal, asset management, and a knowledge base broaden Znuny’s usefulness for internal service operations as well as customer support.

More than 2,000 configuration options, flexible dynamic fields, a modular architecture, and access to the source code allow substantial adaptation. That is valuable when standard processes do not fit, but it is a poor match for teams that want minimal configuration and operational ownership.

Security controls include roles and access rights, identity-management integration, password policies, encrypted email, SSL data transfer, two-factor authentication, and ownership controls. Znuny states that it has held SOC 2 certification since 2024 and ISO/IEC 27001:2022 certification since January 2025, and complies with GDPR requirements. Integrations cover identity systems, web services, monitoring tools, and third-party CRM, catalogue, and database systems. Add-ons include TicketActionLink for triggering web services from tickets and SCIM Identity Provisioning for syncing users and groups from compatible identity providers.

Pricing

The Znuny plan costs free and provides the open-source software free to use. It is the natural starting point for teams able to deploy and operate the platform themselves; paid support is optional rather than a prerequisite for using the core.

Support contracts add configuration, installation, updates, troubleshooting, performance tuning, backup, and recovery, with service-level agreements and guaranteed response times. Each includes support for an associated test system, and agent counts are not limited. Prices are net and exclude VAT.

• Silver support: $4,499 a year. Includes 35 service requests, a 4h maximum reaction time, and 2 authorized support contacts. It suits teams with a limited support workload that can accept the slowest response commitment.
• Gold support: $9,999 a year. Includes 65 service requests, a 2h maximum reaction time, and 3 authorized support contacts. The higher allowance and faster reaction time suit organizations expecting more support needs.
• Platinum support: $28,999 a year. Includes unlimited service requests, a 0.5h maximum reaction time, and 5 authorized support contacts. It is aimed at teams that need the shortest stated reaction time and do not want a request cap.

All three contracts include the test system and have no agent limit, so the tiers differ chiefly in service-request allowance, reaction time, and authorized contacts. The free software avoids a license charge, but paid support is a substantial annual commitment.

Platforms

Znuny supports API, Linux, self-hosted, and web use. It has no mobile apps, a notable limitation for teams whose agents need a dedicated phone or tablet app. The current releases listed are Znuny 7.3.7 and Znuny LTS 6.5.25, both dated 2026-09-16.

Who it's for

Znuny is best for service desks and IT teams that need configurable ticket workflows, multiple intake channels, and service-management tools, especially where open-source access and deployment choice matter. It is less suitable for organizations that need mobile apps or want a low-configuration product without responsibility for deployment and operation.

Pros and cons

• Pro: The open-source core is free, and teams can choose between their own server and Znuny hosting.
• Pro: Broad channels, workflow automation, self-service, SLAs, approvals, and asset management cover more than basic ticket tracking.
• Pro: Extensive configuration and source access support adaptation to specialized processes.
• Pro: Paid support has no agent limit and includes an associated test system.
• Con: Extensive configuration and deployment choices call for technical ownership rather than a turnkey approach.
• Con: There are no mobile apps.
• Con: Support requires annual fees, with request caps on Silver and Gold and different response commitments by tier.

Alternatives

Consider iTop if a free, self-hosted option with Linux and web support is the priority; its Community plan is free of charge and not limited, and it also supports macOS and Windows. Choose FreeITSM for another free option with Linux, web, and Windows support, though it has no free trial.

Vivantio is a paid alternative at $49 a month, billed annually, with published pricing of $49–$99 per agent per month and free end users. GLPI is worth considering if mobile support matters: its platforms include Android and it offers a free plan as well as a public-cloud plan at €19 a month per IT agent.

ZServiceDesk is another service-desk option. Alemba Service Manager may suit teams interested in analyst and occasional-user interfaces, with a license-free self-service portal for end users. ManageEngine ServiceDesk Plus offers a freemium option and paid Standard and Professional plans. OMNITRACKER IT Service Management Center is a paid option for business customers and public institutions, with pricing available on request.

Verdict

Choose Znuny if your organization needs a flexible, open-source service-management platform, values deployment choice, and has the technical capacity to configure and operate it—or budget for support. Its free core and broad workflow capabilities are compelling; look elsewhere if mobile apps or a more turnkey service desk are essential.
