Mattermost

Zulip is open source with topic-based threading inside channels, and can be self-hosted or hosted, unlike Google Chat's Google-only hosting.

Rocket.Chat Desktop is an open-source client for Rocket.Chat workspaces on Windows, macOS and Linux, with server access and licensing handled separately.
Also worth comparing
