What Dify Actually Is

Dify (152,348 stars, 2026-08-14) is an open source LLM app platform: you connect models (OpenAI, Claude, or local Ollama), build apps with a visual workflow editor, add RAG on your documents, and deploy with an API. It is the fastest path from 'idea' to 'working AI app' that runs on your own server.

What You Can Build

Chatbots with RAG - upload your docs, and the app answers from them with citations. The 'Knowledge' feature handles chunking and retrieval without code.

Workflow apps - visual pipelines: trigger -> LLM node -> condition -> tool call -> output. Examples: a content grader, an intent router, a form-filling assistant.

Agents - give the LLM tools (search, calculators, APIs) and let it decide. Dify's agent nodes handle the loop.

API apps - every app auto-exposes an API endpoint with keys, so you can call your Dify app from your website or other services.

The 30-Minute First Build

1. Install Dify (Docker Compose) or use the cloud.
2. Add a model: Settings > Model Provider > add your OpenAI/Ollama key.
3. Create a 'Chatbot' app, add a Knowledge base, upload a PDF.
4. Test in the built-in debugger; publish.
5. Grab the API key and call it from your code.

Workflow vs Chatflow (the two app types)

Dify has two modes: Chatflow (conversation apps, message-by-message with memory) and Workflow (single-shot automation: input -> process -> output, no chat memory). Pick Workflow for one-shot tasks like summarization or classification; Chatflow for anything conversational.

Why Teams Use It

• Self-hosted: data stays on your server (GDPR-friendly).
• Model-agnostic: swap OpenAI for local models in one dropdown.
• Observability: built-in tracing shows every prompt and token.
• Community: 152k stars means templates and plugins for most use cases.

FAQ

Is Dify free? Open source and self-hostable for free; the cloud has free and paid tiers.

Can I use local models? Yes - Ollama and other OpenAI-compatible local endpoints are first-class citizens.

Do I need to code? No - the visual editor covers most apps; an API and plugin system exists for when you do.

Is it production-safe? Yes - many companies run Dify in production; it supports auth, rate limits, and logging.
