The Verdict
Bugzilla is built for open source projects and enterprise it, with a focus on bug-tracking and advanced-search. Harbor targets enterprise devops and container teams and leads with container-registry and vulnerability-scanning.
Both tools use custom enterprise pricing — you'll need to contact sales for a quote, which makes direct cost comparison difficult.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Harbor edges out on user ratings (4.3 vs 3.7). While both are well-regarded, that gap reflects real differences in user satisfaction worth considering.
Feature-wise, Harbor offers broader built-in capabilities (7 features vs 6), while Bugzilla takes a more focused approach — which can mean a simpler, faster onboarding experience.
Bottom line: Harbor has a slight overall edge — but if completely free matters most to you, Bugzilla may still be the right call.
