Overview

A complete platform — prompt orchestration, retrieval, agent tools and an admin UI — that non-engineers can operate once a team has set it up. The licence is a modified Apache 2.0 with additional conditions on multi-tenant hosting and branding, so it is source-available rather than open source. Read it before building a product on top.

What can you do with Dify?

  • Stand it up with Docker ComposeRunning cp .env.example .env then docker compose up -d in the docker/ directory brings the stack up on a 2-core, 4 GiB machine, with initialization at http://localhost/install.
  • Build workflows on a canvasThe visual editor chains LLM steps, retrieval and tools into a workflow you can test in place, and the Prompt IDE compares model performance on the same prompt while you tune it.
  • Give an agent 50+ toolsAgents can be defined on LLM Function Calling or ReAct and handed built-in tools such as Google Search, DALL·E, Stable Diffusion and WolframAlpha, or custom ones you register.
  • Call your apps from your backendEvery Dify offering comes with a corresponding API, and application logs and traces can be routed to Opik, Langfuse or Arize Phoenix for monitoring.
  • Take the self-host past the quickstartConfiguration beyond the defaults lives in docker/.env, with optional advanced variables split by theme under docker/envs/; for a highly available setup the README hands you off to community-contributed Helm charts, Kubernetes YAML, Terraform and AWS CDK templates in outside repositories.

Dify is an open-source LLM app development platform. Its intuitive interface combines AI workflow, RAG pipeline, agent capabilities, model management, observability features (including Opik, Langfuse, and Arize Phoenix) and more, letting you quickly go from prototype to production. Here’s a list of the core features:

Quick start

Before installing Dify, make sure your machine meets the following minimum system requirements:

  • CPU >= 2 Core
  • RAM >= 4 GiB

The easiest way to start the Dify server is through Docker Compose. Before running Dify with the following commands, make sure that Docker and Docker Compose v2.24.0 or later are installed on your machine:

cd dify
cd docker
cp .env.example .env
docker compose up -d

After running, you can access the Dify dashboard in your browser at http://localhost/install and start the initialization process.

3. Prompt IDE: Intuitive interface for crafting prompts, comparing model performance, and adding additional features such as text-to-speech to a chat-based app.

4. RAG Pipeline: Extensive RAG capabilities that cover everything from document ingestion to retrieval, with out-of-box support for text extraction from PDFs, PPTs, and other common document formats.

5. Agent capabilities: You can define agents based on LLM Function Calling or ReAct, and add pre-built or custom tools for the agent. Dify provides 50+ built-in tools for AI agents, such as Google Search, DALL·E, Stable Diffusion and WolframAlpha.

6. LLMOps: Monitor and analyze application logs and performance over time. You could continuously improve prompts, datasets, and models based on production data and annotations.

7. Backend-as-a-Service: All of Dify’s offerings come with corresponding APIs, so you could effortlessly integrate Dify into your own business logic.

Advanced Setup

Custom configurations

If you need to customize the configuration, edit docker/.env. The essential startup defaults live in docker/.env.example, and optional advanced variables are split under docker/envs/ by theme. After making any changes, re-run docker compose up -d from the docker directory. You can find the full list of available environment variables here.

Metrics Monitoring with Grafana

Import the dashboard to Grafana, using Dify’s PostgreSQL database as data source, to monitor metrics in granularity of apps, tenants, messages, and more.

Deployment with Kubernetes

If you’d like to configure a highly available setup, there are community-contributed Helm Charts and YAML files which allow Dify to be deployed on Kubernetes.
