About Dify
Dify is an open-source LLMOps platform that combines a visual workflow builder, RAG pipeline engine, AI agent framework, and model management into a single interface. It lets developers and teams go from AI prototype to production without boilerplate code, supporting self-hosting for full data control. Built by LangGenius, Dify powers over 130,000 AI applications across its cloud and self-hosted deployments.
Pros & Cons
Pros
- Fully open-source and self-hostable for complete data control
- Intuitive visual workflow builder with drag-and-drop canvas
- Built-in RAG pipeline and knowledge base — no external setup needed
- LLM-agnostic: switch between OpenAI, Anthropic, Llama, and more easily
- Fast prototyping — go from idea to MVP in hours with prebuilt patterns
Key Features
Visual Workflow Builder
Design AI pipelines by connecting nodes on a canvas — LLM calls, knowledge base retrievals, conditional branches, code execution blocks, HTTP requests, and more — without writing boilerplate code.
RAG Pipeline & Knowledge Base
Built-in Retrieval-Augmented Generation pipelines let you ingest documents, chunk and clean text, and query your knowledge base to build grounded chatbots and internal assistants.
Agentic AI with Agent Node
The Agent Node enables autonomous decision-making — choosing which tools to call, when to retrieve context, and when to respond — supporting both Function Calling and ReAct reasoning strategies.
Multi-Model & LLM-Agnostic
Connect to and switch between any LLM including OpenAI, Anthropic, Llama, Azure OpenAI, Hugging Face, Replicate, and more from a unified interface.
One-Click API Deployment
Generate a production-ready API from any workflow in one click, with built-in logs showing inputs, outputs, token consumption, and per-node durations for monitoring.
Plugin Marketplace & MCP Support
Expand capabilities with plugins from the marketplace, and publish Dify workflows and agents as standard MCP servers for broad client accessibility.

Best For
RAG Chatbots & Knowledge Base Assistants
Build customer support or internal knowledge assistants that retrieve answers from your documents, manuals, or ticket history with built-in RAG pipelines.
AI Agent Automation
Create autonomous AI agents that call external APIs, query databases, run code, and make decisions without human intervention using the Agent Node.
LLM App Prototyping
Rapidly prototype AI-powered product features and internal tools in hours using prebuilt workflow patterns, then deploy to production via one-click API generation.
Multi-Model Evaluation & Switching
Test and compare outputs from multiple LLMs (OpenAI, Anthropic, open-source) side-by-side to pick the best model for each use case without code changes.
