The Verdict
Mattermost is built for devops teams and security conscious orgs, with a focus on messaging and channels. Memos targets self hosters and quick note takers and leads with markdown and tags.

Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, Memos offers broader built-in capabilities (7 features vs 6), while Mattermost takes a more focused approach — which can mean a simpler, faster onboarding experience.
