Open-Source LLM App Development Platform for Building AI Agents and Workflows

What is Dify?

Dify is an open-source LLM application development platform that bridges the gap between large language model capabilities and production-ready software. Rather than building AI applications from scratch with raw API calls and custom orchestration code, Dify provides a visual, low-code environment where developers and product teams can design AI workflows, configure RAG (Retrieval-Augmented Generation) pipelines, build autonomous agents, and deploy them as APIs or web applications.

The platform supports all major LLM providers including OpenAI, Anthropic, Google, Mistral, and local models through Ollama. This vendor-agnostic approach means teams can switch between models without rewriting their application logic. Dify also includes enterprise features like team collaboration, role-based access control, usage analytics, and logging — making it suitable for both individual developers and large organizations building AI-powered products at scale.

Product Features

  • Visual Workflow Builder: Design complex AI workflows using a drag-and-drop interface that chains together LLM calls, conditionals, tool usage, data transformations, and human-in-the-loop reviews without writing orchestration code
  • RAG Engine: Upload documents, websites, and data sources, and Dify automatically chunks, embeds, and indexes them for retrieval-augmented generation with configurable chunking strategies and embedding models
  • Agent Framework: Build autonomous AI agents that can use tools, browse the web, execute code, and make multi-step decisions — with configurable agent strategies including ReAct, function calling, and custom orchestration
  • Multi-Model Support: Connect to OpenAI, Anthropic, Google, Mistral, Cohere, and local models via Ollama. Switch between providers with a single configuration change, no code refactoring required
  • One-Click API Deployment: Every workflow and agent can be deployed as a REST API with authentication, rate limiting, and usage tracking — ready for integration into your existing applications
  • Observability and Logging: Monitor every LLM call, token usage, latency, and error in real time. Debug workflows by stepping through each node and inspecting inputs and outputs

Product Highlights

  • Open-Source and Self-Hostable: The core platform is open-source under the Apache 2.0 license, allowing teams to deploy it on their own infrastructure for data privacy, compliance, and cost control
  • Vendor-Neutral Model Integration: Abstract away LLM provider differences so your application logic works regardless of which model is powering it — future-proofing against provider changes and price increases
  • Enterprise-Grade Collaboration: Built-in team management, role-based permissions, and shared workspaces make it possible for multiple developers and non-technical stakeholders to collaborate on AI applications
  • Production-Ready from Day One: Unlike experimental frameworks, Dify includes the operational features needed for production deployment — logging, monitoring, error handling, and scaling — out of the box

Use Cases

  • Product teams building AI chatbots: Create sophisticated customer support chatbots with RAG-powered knowledge bases, multi-step reasoning, and tool usage without managing infrastructure or writing custom orchestration code
  • Enterprises deploying internal AI tools: Build private AI assistants that access internal documentation and data while keeping everything on-premises for compliance with data governance policies
  • Developers prototyping AI features: Rapidly prototype and iterate on AI-powered features by visually designing workflows, testing with different models, and deploying as APIs for integration into existing products
  • Data teams creating RAG pipelines: Upload internal knowledge bases, configure chunking and embedding strategies, and deploy retrieval-augmented Q&A systems that provide accurate, sourced answers from proprietary data
  • SaaS companies adding AI capabilities: Integrate Dify-powered AI workflows into existing SaaS products via API, adding intelligent features like document summarization, content generation, and data analysis without building AI infrastructure from scratch
