The Verdict
Mattermost is built for devops teams and security conscious orgs, with a focus on messaging and channels. Missive targets agencies and startups and leads with shared-inboxes and team-chat.
Pricing is close: Mattermost starts at $10/mo versus $14/mo for Missive — 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.
Bottom line: Missive has a slight overall edge — but if self-hostable matters most to you, Mattermost may still be the right call.
