Pros
  • Official, well-tested abstractions
  • Same primitives as Claude Code
  • Strong tool-use ergonomics
  • TypeScript + Python SDKs
  • Open source and self-hostable with a permissive license
  • Visual graph maps cleanly to LangChain concepts developers already know
  • Broad LLM and vector-DB coverage out of the box
  • Every node is editable Python, not a locked black box
  • Flows deploy as APIs without extra glue code
Cons
  • Claude-only
  • Newer than LangGraph/CrewAI
  • Fast-moving codebase; version upgrades can break existing flows
  • Visual metaphor still assumes LangChain-level familiarity
  • Hosted tier is tied to DataStax's Astra ecosystem
