Dify - Pros & Cons
Pros
- ✓Open-source self-hosted path keeps long-term costs and data residency under your control
- ✓Model-agnostic gateway lets you swap providers without rewriting workflows
- ✓Strong built-in RAG with rerankers, metadata filters, and multiple chunking strategies
- ✓Production-ready observability: traces, prompt versioning, annotations, cost tracking
- ✓Active plugin marketplace with growing MCP-compatible integrations
Cons
- ✗Complex agent logic with many branches is harder to express than in code-first frameworks
- ✗Cloud message credits get expensive fast at production volume — most heavy users self-host
- ✗Plugin ecosystem is smaller than n8n or Zapier; niche integrations often need custom work
- ✗Visual editor learning curve is real for non-technical users despite the no-code framing
- ✗Self-hosting requires Docker, Postgres, Redis, and a vector DB — not a zero-ops deployment
