Pros
  • User reportsUsers find it fast for prototyping, with role-based agents that are intuitive to set up.[1]
  • User reportsSeparate agents, tasks and tools, plus YAML config for roles and models, keep behaviour changes out of code.[1]
  • MetadataMIT licensed and released very often (1.15.33 on Oct 29, 2026).[1]
  • User reportsVery easy start for function calling and sub-agents-as-tools; with the Responses API you don't have to store input items yourself.[1]
  • User reportsOne long-time user says they are largely happy with its abstractions: handoffs, tools, guardrails and structured output.[1][2]
  • DocsProvider-agnostic despite the name (100+ LLMs), with built-in tracing, sessions, sandbox agents and realtime/voice agents.[1]
  • User reportsCommenters see it as simpler than heavier frameworks like Google ADK or LangChain, and its backlog is small (about 12 open issues).[1][2]
Cons
  • User reportsUsers report the whole crew hanging when one agent or API call times out; one moved the pipeline to LangGraph.[1]
  • User reportsThe early simplicity becomes a constraint: users report hard-to-reproduce drift on long tasks and a 'loose and underspecified' abstraction.[1][2]
  • User reportsForum users report poor visibility into agent decisions, roughly 10-minute crew runs, and a virtualenv near 1 GB.[1]
  • User reportsInfra, observability and reliable scaling are left to you, and one user found those were the bigger pain.[1]
  • User reportsOne user calls it messy internally, citing inconsistent use of its own enums.[1]
  • User reportsSome teams used it extensively and then moved to their own framework.[1]
Best forDemos and internal multi-agent prototypes where speed to a first result matters more than determinism.Python teams that want lightweight multi-agent primitives (handoffs, guardrails, tracing) with first-class OpenAI Responses and realtime support.
Watch out forTimeouts, hangs and limited observability; plan your own monitoring before production.Production concerns like durability, scaling and approvals are on you; plan that layer early.
