The Verdict
MantisBT is built for developers and small teams, with a focus on bug-tracking and custom-fields. Trigger.dev targets typescript developers and saas apps and leads with background-jobs and scheduled-tasks.
Pricing is close: Trigger.dev 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.
Trigger.dev edges out on user ratings (4.4 vs 3.9). While both are well-regarded, that gap reflects real differences in user satisfaction worth considering.
Feature-wise, Trigger.dev 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: Trigger.dev has a slight overall edge — but if free and open-source matters most to you, MantisBT may still be the right call.
