Kioko M.LecturerLeisure, Travel & Tourism, 11-50 employees

"Mattermost unify teams in one place through unlimited communication channels in one place."

Joseph A.Mechanical EngineerConstruction, 201-500 employees

"Even though it synchronizes messages after connecting to the internet, it doesn’t support offline access."

Apr 30, 2024

Jake P.Account ExecutiveHospital & Health Care, 1001-5000 employees

"The file sharing mechanism is very smooth—we can drop images and documents straight into a chat, and the search functionality is powerful enough to find old files or specific conversations from months ago using simple keywords."

Arthi R.EngineerAccounting, 1001-5000 employees

"Its free plan has limited message history and integrations. While it’s great for real-time chat, Slack isn’t ideal for long-form discussions or detailed project management."
