The Verdict
Mattermost is built for devops teams and security conscious orgs, with a focus on messaging and channels. Umami targets indie developers and privacy focused sites and leads with page-views and custom-events.
Pricing is close: Umami starts at $9/mo versus $10/mo for Mattermost — 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.
Feature-wise, Umami offers broader built-in capabilities (7 features vs 6), while Mattermost takes a more focused approach — which can mean a simpler, faster onboarding experience.
Bottom line: Umami has a slight overall edge — but if self-hostable matters most to you, Mattermost may still be the right call.
