Security

Open source: data handling per configured LLM providers. LangSmith deployment: review LangChain data handling policy.

SOC 2 Type II. GDPR compliant. SSO and audit logs on enterprise plans. Private deployment for data sovereignty.

Privacy notes

Data handling entirely through configured AI provider APIs. LangGraph itself does not transmit data. LangSmith deployment subject to LangChain's privacy policy.

Review Stack AI data handling policy. Enterprise private deployment keeps data within customer infrastructure.

Verdict
Pros
  • Graph-based control flow enables iterative agent behaviour unavailable in simple chains
  • Persistent state enables truly stateful multi-session agents
  • Human-in-the-loop checkpoints essential for production agent safety
  • Deep LangChain ecosystem integration for developers already on that stack
  • No-code visual builder accessible to enterprise business teams without ML engineering
  • Document processing pipelines strong for legal, healthcare, and financial services
  • Enterprise governance features (SSO, audit logs, RBAC) meet corporate requirements
  • Private deployment option for data sovereignty requirements
Cons
  • Steeper learning curve than CrewAI for developers new to graph-based thinking
  • Complexity overkill for simple single-turn AI tasks
  • LangChain dependency may be limiting for teams using other frameworks
  • $199/month Starter plan is expensive relative to open source alternatives like Flowise
  • Most value in document processing rather than general AI application building
  • Less flexibility than coded frameworks for highly custom AI logic
