What is the best free Slack alternative?

Microsoft Teams is free with a Microsoft account and has no message history limit on the free plan. Discord is excellent for informal team communication with a very generous free tier.

Is Microsoft Teams better than Slack?

For teams already on Microsoft 365, Teams is the better choice — it's included at no extra cost and integrates deeply with Office apps. For teams without Microsoft 365, Slack's UX and integrations are often preferred.
