The Verdict
Bugzilla is built for open source projects and enterprise it, with a focus on bug-tracking and advanced-search. osTicket targets small businesses and budget conscious teams and leads with ticket-management and email-piping.
Bugzilla uses custom enterprise pricing, while osTicket starts at $12/mo — a tangible advantage for teams with a fixed budget.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Bottom line: osTicket has a slight overall edge — but if completely free matters most to you, Bugzilla may still be the right call.
