Znuny review
A flexible open-source help desk with mature ticket, queue, SLA, and portal tools.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Znuny is an open-source ticket management and IT service management platform for customer service, internal support, and enterprise service operations. It is suited to teams that need structured ticket and queue management across email, phone, customer portals, monitoring tools, and web services. Its feature set also covers workflow automation, SLA tracking, escalation notifications, customer and company records, permissions, knowledge content, self-service, and reporting.
The self-hosted open-source edition is free to use, modify, and redistribute under the GPL v3 license. Teams can instead choose managed hosting through Silver, Gold, or Platinum. Silver includes 250GB of storage, 35 service requests, dedicated hardware, a test system, daily backup, and monitoring. Gold increases storage to 500GB and service requests to 65, while retaining dedicated hardware, a test system, daily backup, and monitoring. Platinum provides 750GB of storage, unlimited service requests, a 24x7 service level window, dedicated hardware, and read-only database access. The managed plans are system-based rather than per-user.
Znuny’s integration and deployment model will appeal to organizations with existing IT service processes. REST and SOAP web services support external connections, while LDAP, Active Directory, SQL databases, and system monitoring tools fit common operational environments. Role, group, and queue permissions help divide responsibilities across support teams, and the customer portal and FAQ knowledge base extend service beyond the agent interface. The trade-off is scope: teams seeking a lightweight hosted inbox may find this broader operational model more involved than necessary. Znuny fits best when open-source control, customizable workflows, service-level tracking, and enterprise-oriented integrations matter more than minimal setup.
