kaboo is three libraries that snap together. Pick the path that matches what you want to build — you can always add the others later.

I want to orchestrate agents

Define models, agents, tools, MCP servers, and multi-agent orchestrations (delegate / swarm / graph / parallel / nested) in YAML, then serve them as an AG-UI SSE endpoint. load() returns plain strands objects, so you can also drive agents in-process.

→ kaboo-workflows · Getting started

I want to persist and replay runs

Drop a plugin into a CopilotKit runtime (NestJS or any Node framework) that records the full event log per thread and replays it on reconnect — so a browser refresh mid-run or post-run restores exactly what happened. Ships an InMemoryThreadStore and a PostgresThreadStore.

I want to render agent activity

Drop-in React components + hooks that turn the AG-UI run stream into a live, hierarchical activity tree with drill-down and human-in-the-loop, inside a CopilotKit chat.

→ kaboo-react · Concepts

I want the whole stack

Wire all three end-to-end: YAML agents → served over AG-UI → persisted in a CopilotKit runtime → rendered in React, backed by Postgres.
