The Verdict
Bugzilla is built for open source projects and enterprise it, with a focus on bug-tracking and advanced-search. ZenHub targets development teams and github users and leads with kanban-boards and epics.
Bugzilla uses custom enterprise pricing, while ZenHub starts at $8.33/mo — a tangible advantage for teams with a fixed budget.
Bugzilla has a free plan, which gives it a meaningful edge for individuals and small teams exploring their options. ZenHub requires a paid subscription from day one.
ZenHub edges out on user ratings (4.2 vs 3.7). While both are well-regarded, that gap reflects real differences in user satisfaction worth considering.
Both tools are a solid fit for open source projects — in those cases, the decision often comes down to workflow style and how your team prefers to organize work.
Bottom line: ZenHub has a slight overall edge — but if completely free matters most to you, Bugzilla may still be the right call.
