About the team chat category
Team chat pricing in 2026 is a commoditization story. Microsoft Teams Essentials at $4/user/mo annual undercuts everyone — if your team doesn't need Slack-specific features (Workflow Builder, third-party integrations), Teams is dramatically cheaper. Slack Pro at $8.75/user/mo annual is 2.2x Teams but wins on third-party app integrations (Zapier, Notion, etc.) and UX polish. Discord remains the community/gaming-first free option that some dev teams adopt. Rocket.Chat and Mattermost compete on self-hosting for data sovereignty. Enterprise Grid pricing is opaque and negotiable.
How to choose: buying criteria for team chat
Answer three questions. First: are you already in Microsoft 365 or Google Workspace? If Microsoft 365, Teams is free or included in your Business Standard ($12.50/user/mo). If Google Workspace, consider Google Chat (free, included). No need for a separate chat subscription. Second: do you need third-party app integrations? Slack wins on ecosystem — 2,600+ apps vs Teams' 1,200+. Third: data sovereignty / self-hosting requirements? Rocket.Chat Starter (free, up to 50 users) or Mattermost self-hosted — both offer enterprise-grade features without cloud commitment.
