The Verdict
MantisBT is built for developers and small teams, with a focus on bug-tracking and custom-fields. Rocket.Chat targets security conscious organizations and government and leads with channels and direct-messaging.
Both tools come in at similar price points ($4.95/mo for MantisBT, $4/mo for Rocket.Chat), 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.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
