When to Use Code Instead

  • Complex business logic that's hard to express visually.
  • Performance-critical paths where overhead matters.
  • Custom model training or fine-tuning pipelines.

Choosing a Platform

Your choice depends on team size, technical depth, and deployment requirements. Dify is best for teams wanting a visual builder with built-in RAG and agent capabilities. n8n excels at connecting diverse services with its 400+ integrations. LangFlow is ideal for ML engineers who want fine-grained control over LLM chains. For enterprise needs, Flowise offers self-hosted deployment with SSO and audit logs.

Key Decision Factors

  • Self-hosted vs cloud: Dify, n8n, and Flowise can all be self-hosted via Docker. LangSmith Cloud is managed-only.
  • Visual vs code: Dify and n8n are visual-first. LangFlow bridges visual and code. For pure code, use LangChain or LlamaIndex directly.
  • Community and support: n8n has the largest community (40K+ GitHub stars). Dify is fastest-growing (30K+ stars). Enterprise support is available for all major platforms.
