osTicket is free because you run it yourself. Once you count the server, the upgrades and the evening someone spends patching it, “free” starts to look expensive.

Comparison based on publicly available information as of 2026 — verify current details with osTicket.
osTicket is genuinely free, open source and self-hosted — which is the right answer if you must keep every ticket on your own infrastructure and you have the people to run it.
If you want a simpler, AI-first help desk and PSA with a genuine free plan, Vertask is a strong osTicket alternative for lean IT teams and small MSPs. Choose osTicket if self-hosting is a requirement and you have someone to maintain it. Choose Vertask if you want the same zero starting cost without owning a server.
Yes. Vertask has a free plan (up to 2 agents, no credit card) covering ticketing, knowledge base, client management and Insight AI. osTicket can also be started for free, so the question is what you get with it — the comparison above sets the two side by side.
