Mozaik: A TypeScript Runtime Where the Agents Decide the Workflow, Not a Predrawn DAG

Trending on Product Hunt (July 6), Mozaik is an open-source TypeScript framework for self-organizing agent teams built on a reactive event bus — every message, tool call, and error is an event agents subscribe to, and collaboration emerges at runtime instead of from a hardcoded graph. That's a real architectural departure from LangGraph/CrewAI-style up-front DAGs. For TS builders, the small first-integration path (define a few agent participants, share an environment) lowers the bar to try event-driven multi-agent coordination.
