Zero

Run multi-agent crews with live traces, answer modes, and workspace context.

Read the guide GitHub

Zero is the runtime for Lab Z crews. Users chat in a workspace; a director routes work to specialists; a synthesizer composes the answer. You see agents and tools appear on a live execution graph as the run progresses.

What you get

  • FastAPI + React stack with streaming chat (SSE)
  • Swappable crews via load-crew.sh / AGENT_CONFIG_DIR
  • Answer modes from crew.yaml
  • Rich response tabs: summary, data tables, visualizations, references
  • Org workspaces with shared files that agents can search

When to use it

Ship a crew to people who need durable threads, modes, and evidence — not a disposable CLI session.

Pair with CrewDefine

Author in CrewDefine → validate → load into Zero → chat. Details: Getting started.

Fastest try: from a Zero checkout, ./scripts/demo.sh loads Technical Due Diligence with no CrewDefine install.
