What it is
Dify is an open-source platform for building LLM applications. Through visual orchestration you can wire models, knowledge bases and tools into a working AI app, then publish it as an API or web app with one click.
Highlights
- Visual workflow editor with branches, loops and human-in-the-loop nodes
- Built-in RAG pipeline with solid document parsing and retrieval out of the box
- Model-agnostic: OpenAI, DeepSeek and local models all supported
Who it is for
Teams validating AI app ideas fast, enterprises building knowledge-base Q&A, and indie developers avoiding backend work. Note the license adds commercial restrictions on top of Apache-2.0 — multi-tenant SaaS use needs a license check.
