All three apps send messages, share files and run video calls. The real differences show up later: who can join a channel from outside your company, what your plan includes, and how well the app works with the documents and calendar you already use.
The short version:
- On Microsoft 365? Teams usually gives you the most for your money.
- On Google Workspace? Google Chat is the natural fit.
- Want the biggest app marketplace, or work a lot with clients in shared channels? Slack is the strongest, but you pay for it separately.
We compared the three on features, pricing, integrations, security, external collaboration and AI.
