Dify
Open-source LLM app development platform with visual workflow, RAG, and agent builder
Overview
Dify is a production-grade open-source platform for building LLM applications, offering a workflow designer, RAG pipeline with knowledge base management, agent orchestration, and an observability dashboard. It supports dozens of model providers and can be self-hosted via Docker Compose with a PostgreSQL + Redis backend.
Where it falls short of ChatGPT
- Self-hosted community edition lacks SSO and audit logs (cloud-only)
- Requires multiple services (Postgres, Redis, Weaviate/Qdrant) increasing ops burden
- Plugin marketplace is smaller than commercial AI platforms
We list the gaps honestly so you can decide if the trade-off is worth owning your data.
