The Verdict
Mattermost is built for devops teams and security conscious orgs, with a focus on messaging and channels. Microsoft Clarity targets small businesses and startups and leads with session-recordings and heatmaps.
Microsoft Clarity uses custom enterprise pricing, while Mattermost starts at $10/mo — a tangible advantage for teams with a fixed budget.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, Microsoft Clarity 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: Microsoft Clarity has a slight overall edge — but if self-hostable matters most to you, Mattermost may still be the right call.
