The Verdict
Immich is built for self hosters and families, with a focus on photo-backup and facial-recognition. MantisBT targets developers and small teams and leads with bug-tracking and custom-fields.
Pricing is close: Immich starts at $0/mo versus $4.95/mo for MantisBT — not a deciding factor on its own.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Immich edges out on user ratings (4.7 vs 3.9). While both are well-regarded, that gap reflects real differences in user satisfaction worth considering.
Feature-wise, Immich offers broader built-in capabilities (7 features vs 6), while MantisBT takes a more focused approach — which can mean a simpler, faster onboarding experience.
Bottom line: Immich has a slight overall edge — but if free and open-source matters most to you, MantisBT may still be the right call.
