the problem

The problem it solves#

Online communities often outgrow basic chat when they need richer moderation, custom bots, economies, multiple conversation surfaces, and provider flexibility. Closed platforms can make those workflows dependent on vendor rules and opaque data policies.

Community operators need chat infrastructure they can inspect and adapt. That matters when bots, APIs, moderation, and uptime are central to how the community works.
