The Verdict
Bugzilla is built for open source projects and enterprise it, with a focus on bug-tracking and advanced-search. Windmill targets developers and devops teams and leads with workflow-editor and script-to-ui.
Bugzilla uses custom enterprise pricing, while Windmill starts at $10/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.
Windmill edges out on user ratings (4.4 vs 3.7). While both are well-regarded, that gap reflects real differences in user satisfaction worth considering.
Feature-wise, Windmill offers broader built-in capabilities (7 features vs 6), while Bugzilla takes a more focused approach — which can mean a simpler, faster onboarding experience.
Both tools are a solid fit for developers — in those cases, the decision often comes down to workflow style and how your team prefers to organize work.
Bottom line: Windmill has a slight overall edge — but if completely free matters most to you, Bugzilla may still be the right call.
