The Verdict
Element is built for open source teams and governments, with a focus on encrypted-messaging and voice-video-calls. MantisBT targets developers and small teams and leads with bug-tracking and custom-fields.
Both tools come in at similar price points ($5/mo for Element, $4.95/mo for MantisBT), so pricing won't make the decision for you.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Element edges out on user ratings (4.2 vs 3.9). While both are well-regarded, that gap reflects real differences in user satisfaction worth considering.
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: Element has a slight overall edge — but if free and open-source matters most to you, MantisBT may still be the right call.
