The Verdict
Mattermost is built for devops teams and security conscious orgs, with a focus on messaging and channels. Zeplin targets design teams and developers and leads with design-handoff and style-guide.
Pricing is close: Mattermost starts at $10/mo versus $12/mo for Zeplin — 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.
