What works
  • Clear mental model for multi-agent work
  • Large community and examples
  • Free to run yourself
  • Enormous ecosystem and documentation

  • Agent loops can run away on cost
  • Abstractions leak on complex flows
  • Abstractions add indirection

  • Easy to over-engineer with
  • Does not publish a price on its own site, so the cost is only clear after signing up
