Sustainable, community‑driven ticketing system for modern support teams
Znuny continues the OTRS Community Edition, delivering a maintained, stable, and highly tailorable web‑based ticketing platform for customer service, help desk, and IT service management.
Znuny is a continuation of the OTRS Community Edition (v6.0.30) that provides a reliable, self‑hosted ticketing system. It targets customer service, help‑desk, and IT service management teams that need a highly customizable solution while retaining long‑term sustainability through active community stewardship.
The platform runs on Linux (Debian or Red Hat) with Perl 5.16+, Apache 2 + mod_perl2 (or CGI) and supports MySQL 8+, MariaDB 10.3+, PostgreSQL 12+, and Oracle 19c+. Its GPL‑3 license ensures transparency and freedom to modify. Documentation, community forums, Discord, and commercial services are available for onboarding and ongoing support. Znuny’s modular architecture lets organizations tailor workflows, fields, and notifications to match specific processes, making it suitable for a wide range of support environments.
Ideal for organizations with in‑house technical expertise that prefer a self‑managed, extensible ticketing solution over SaaS alternatives, while still benefiting from an active development community.
When teams consider Znuny, these hosted platforms usually appear on the same shortlist.
