Pros
  • Open-source framework with 40K+ GitHub stars and active community
  • Supports 30+ model providers, so no lock-in to one LLM vendor
  • AgentOS runs in your own cloud — good for regulated data
  • Interops with LangGraph, DSPy, and Claude Agent SDK
  • Ships auth, RBAC, audit logs, and approval workflows out of the box
  • Git-style version history and activity log for every prompt change
  • Remix sandbox isolates experiments from production prompts

Cons

  • Python-only — no first-class TypeScript/Node story
  • Younger project than LangChain; smaller docs surface area
  • Self-hosting AgentOS still means you own the infra
  • No free tier; cheapest plan is $20/mo
  • Stingy token allowance (5K/seat) for in-app testing
  • Lighter on observability/analytics than Langfuse or Helicone
  • Supported model providers not clearly listed on the site
