Prose
Prose offers an open source alternative to Slack and Teams, with plans and information for large nonprofits and education groups.
About Prose
Prose is a self-hosted workplace chat application presented on its site as an alternative to Slack and Teams. Teams install the Prose server on their own premises, then install the Prose apps on members' devices; the site says setup takes about five minutes. Messages and chat history are end-to-end encrypted, images and large files can be shared, and the service is powered by XMPP. The site says it scales from small to very large teams and describes the project as open source and decentralized, with the foundation noted as a non-profit funded by Valerian Saliou and made in the EU.
Several capabilities are not yet available: integrations, powerful search, and audio and video calls with screen sharing are all marked as planned. Pricing details are not given on the homepage, although the site states the Prose server can be installed on your own premises for free. Because the server is self-hosted, running and administering it is the operator's responsibility.
