Pros
  • Human-in-the-loop gates are first-class nodes, not an afterthought bolted onto an autonomous loop
  • Real Docker sandbox per run with scoped Git credentials, safer than giving an agent your full token
  • Multi-agent: mix Cursor, Claude Code, CodeBuddy, and Trae in the same workflow
  • Visual FSM canvas makes complex agent pipelines legible and reviewable
  • MCP-based artifact contracts give downstream nodes typed inputs instead of blob prompts
  • MIT-licensed and self-hostable, with a REST API for CI/internal tool integration
  • Execution visibility (timeline, logs, artifacts, token usage) helps postmortem agent runs
  • Reliable, debuggable agent graphs
  • Built-in persistence + HITL
  • Production-grade
  • Tight LangSmith integration
Cons
  • Self-hosted only; no managed SaaS, so you own the Docker host, upgrades, and secrets
  • Setup requires Linux plus Docker Compose and separate ACP backends configured per agent
  • Young project with limited public case studies and thin end-user documentation
  • Backend catalogue is coding-agent focused; not a general LLM orchestration tool
  • Human approval gates add latency, so it fits deliberate delivery flows more than rapid prototyping
  • Steeper learning curve than CrewAI
  • Verbose to set up
