    Workplace chat is critical infrastructure, but most teams rent it from a single proprietary vendor. That creates lock-in around accounts, message history, integrations, pricing, and data residency.

    XMPP offers a federated messaging foundation, but many XMPP clients feel built for hobbyist chat rather than workplace collaboration. Prose aims to bring a modern team-communication experience to that open protocol base.

    Prose is best for teams and communities that value open messaging protocols and control over communication infrastructure.
