Microsoft Teams (free)
The free edition of Microsoft Teams for chat, file sharing and video meetings.
Microsoft Teams (free) combines chat, file sharing and meetings for up to 100 participants, but requires a Microsoft account and remains proprietary with business features on paid plans.
Google Chat
Google's team messaging app with spaces, direct messages and threaded conversations.
Google Chat offers spaces with threaded conversations and fits teams already in Google Workspace, but it needs a Google account, runs in the web only and cannot be self-hosted.
Mattermost
A self-hosted team chat platform with a desktop client, aimed at organisations that want Slack without the cloud.
Mattermost is open source under Apache-2.0 and self-hosted, so message data stays on your own servers, though you must run the server and some features are paid.
Zulip
Team chat organised by topic inside each channel, so conversations stay readable when you come back hours later.
Zulip is open source and organises chat by topic inside each channel, can be self-hosted or hosted, but has a smaller integration ecosystem than Slack.

Rocket.Chat Desktop is an MIT-licensed client for Rocket.Chat workspaces, which you connect to separately, with server licensing handled apart from the desktop app.
Pumble

Pumble keeps a similar channel and thread layout with unlimited users and message history on its free offering, but it is closed source and hosted only.
Campfire
A self-hosted group chat system from 37signals with rooms, direct messages and @mentions.
Campfire from 37signals is MIT licensed and self-hosted with no per-user fees, but covers chat basics rather than a large integration ecosystem.
