The Verdict
MantisBT is built for developers and small teams, with a focus on bug-tracking and custom-fields. SeaTable targets privacy conscious teams and european companies and leads with spreadsheet-interface and python-scripting.
Pricing is close: MantisBT starts at $4.95/mo versus $7/mo for SeaTable — 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.
SeaTable 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.
Bottom line: SeaTable has a slight overall edge — but if free and open-source matters most to you, MantisBT may still be the right call.
