This system has run helpdesks at a scale most modern tools never reach - and it looks like it was designed in the era when it earned that reputation, because it was. Both halves of that sentence are true. Here is the graded verdict, so you choose it for its real strengths instead of discovering its age later.
Honest reviews matter more for software you will live in daily than for software you install once. The OTRS family - today continued as Znuny - is a genuinely deep ticket system with a visibly old surface, and pretending either half away helps nobody. Below: where it is still excellent, where it honestly shows its age, who it fits, and who should pick something else - including the other helpdesks covered on this channel.
The depth is real. Queues, groups and granular permissions handle complicated organisations without blinking. Tickets can carry dynamic fields for the extra data your process needs, escalations and service-level agreements keep old tickets from dying quietly, the mail engine's follow-up matching is battle-tested, and the statistics module answers management questions most small tools cannot. This is not reputation by nostalgia - the Wikimedia Foundation trusted it with its volunteer support for years, at a volume that breaks lesser systems.
Choose it if you want a self-hosted helpdesk you fully control, with no per-agent monthly fee, real ticket discipline, and the depth to grow from a three-person desk to a department. It suits IT teams and offices already comfortable running a Linux server, and organisations whose data must stay on their own machines. The licence cost is zero; the honest cost is administrator time, and for the right team that trade is heavily in its favour.
Look elsewhere if you want zero administration, a chat-first modern interface, or a tool a non-technical team can run without an admin at all - a hosted product will serve you better and the saving here is false economy. This channel also covers Faveo for a simpler open-source helpdesk and Jira when you need the Atlassian ecosystem, so watch those videos and compare before you commit.

It can be. It will work perfectly well, but you are adopting a real platform with an admin learning curve. If your desk is tiny and always will be, a simpler tool may fit better; if you expect to grow or need the depth, the headroom is worth it.
Yes - service-level agreements, escalations and a statistics module are among its core strengths, not paid extras. That depth is a large part of why organisations ran it at serious scale for so long.
