Alternatives to Microsoft Teams

Microsoft Teams is an enterprise collaboration platform combining persistent chat, video conferencing, file sharing, and Office 365 integration, launched by Microsoft in 2017 as a direct Slack competitor and growing to 300 million monthly active users by 2023 — the largest collaboration platform by users. Teams' explosive growth stems almost entirely from Office 365 bundling: most enterprise Microsoft licenses include Teams at no extra cost, making it the default collaboration tool for organizations already paying for Outlook, SharePoint, OneDrive, and Office apps.
