Microsoft Teams bundles chat, meetings, and files at $4-7 per user per month (or folded into Microsoft 365 at $6-12.50). For small teams that do not live inside Office, free tools like Slack's free tier, Google Chat, and Discord cover chat and video without per-seat fees. Here are the best free Microsoft Teams alternatives.
| Alternative | Price | Best For | No Signup? |
|---|---|---|---|
| Slack (Free Tier) | Free (90-day message history) | Polished team chat with apps | Account needed |
| Google Chat + Google Meet | Free (with Google account) | Teams already on Google Workspace | Account needed |
| Discord | Free | Communities & voice-first teams | Account needed |
| Mattermost (Self-Hosted) | Free (open source) | Owned, private team chat | ✅ Yes |
| Rocket.Chat | Free (open source) | Full chat + video in one open platform | ✅ Yes |
Slack's free plan supports unlimited users with 90-day message history, 10 app integrations, huddles, and 1:1 video calls. If your team mostly chats and uses a separate video tool, Slack free is the most polished Teams alternative.
Google Chat provides threaded team messaging with Spaces, and Meet adds group video calls for up to 100 participants — both free with a Google account. Together they replicate the core Teams chat-plus-video workflow at $0.
Discord offers unlimited servers, channels, and voice rooms free, with screen sharing and 25-person video calls. It is the fastest free option for teams that communicate heavily by voice.
Mattermost is an open-source Slack/Teams alternative you host yourself — unlimited users, channels, file sharing, and integrations with full data ownership. No per-user pricing, ever.
Rocket.Chat combines team chat, channels, and free video conferencing in one self-hosted platform, with an omnichannel inbox for customer support. It is the most complete all-in-one free Teams replacement.
