Dify
RAGとエージェントを内蔵したLLMアプリのビジュアルビルダー
概要
プロンプトのオーケストレーション、検索、エージェントツール、管理UIまでを備えた統合プラットフォームで、初期構築さえ済めば非エンジニアでも運用できます。ライセンスはApache 2.0に、マルチテナント提供とブランディングに関する追加条件を加えたもので、OSSではなくソース公開型にあたります。この上に製品を構築する前に必ず確認してください。
Difyで何ができますか?
- Docker Composeで立ち上げる —
docker/ディレクトリでcp .env.example .envとdocker compose up -dを実行すれば2コア・4GiBの環境で起動し、http://localhost/installから初期設定に進めます。 - キャンバス上で処理をつなぐ — ビジュアルエディタでLLM呼び出し・検索・ツールをワークフローとしてつなぎ、その場で試せます。Prompt IDEでは同じプロンプトに対するモデルごとの挙動を比較できます。
- エージェントにツールを持たせる — Function CallingまたはReActを基にエージェントを定義し、Google Search、DALL·E、Stable Diffusion、WolframAlphaなど50以上の内蔵ツールや自作ツールを割り当てられます。
- 自社バックエンドから呼び出す — 作成したアプリはいずれもAPIとして提供され、ログとトレースはOpik、Langfuse、Arize Phoenixへ流して監視できます。
- 自ホスト構成を本番仕様に寄せる — 既定値から外れた設定は
docker/.envに書き、テーマ別に分かれた任意項目はdocker/envs/以下にあります。高可用構成についてはREADMEの案内がコミュニティ提供のHelmチャートやKubernetes用YAML、Terraform、AWS CDKといった外部リポジトリに委ねられています。

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.

Key features
1. Workflow: Build and test powerful AI workflows on a visual canvas, leveraging all the following features and beyond.
2. Comprehensive model support: Seamless integration with hundreds of proprietary / open-source LLMs from dozens of inference providers and self-hosted solutions, covering GPT, Mistral, Llama3, and any OpenAI API-compatible models. A full list of supported model providers can be found here.
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.
