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](https://www.comet.com/docs/opik/integrations/dify), [Langfuse](https://docs.langfuse.com), and [Arize Phoenix](https://docs.arize.com/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
<br/>
The easiest way to start the Dify server is through [Docker Compose](docker/docker-compose.yaml). Install [Docker](https://docs.docker.com/get-docker/) with a running daemon, Docker Compose v2.35.0 or later, and OpenSSL.
For a new deployment, run the following commands from the repository root. For an existing deployment, preserve your `.env` and follow the [upgrade guidance](docker/README.md#review-configuration-after-an-upgrade).
```bash
cd docker
cp .env.example .env
openssl rand -hex 32
```
Open `.env` and set `DIFY_AGENT_LOCAL_SANDBOX_AUTH_TOKEN` to the generated value. Keep the default `COMPOSE_PROFILES` value for the bundled services. Service defaults load automatically; no additional configuration files are required.
From the same `docker` directory, start the services:
```bash
docker compose up -d
docker compose ps --all
```
Once the services are running, open [http://localhost/install](http://localhost/install) to complete the initial setup. The one-time `init_permissions` service is expected to exit with code `0`.
For optional settings and service overrides, see the [Docker deployment guide](docker/README.md#configure-dify).
### Seeking help
Please refer to our [FAQ](https://docs.dify.ai/getting-started/install-self-hosted/faqs) if you encounter problems setting up Dify. Reach out to [the community and us](#community--contact) if you are still having issues.
> If you'd like to contribute to Dify or do additional development, refer to our [guide to deploying from source code](https://docs.dify.ai/getting-started/install-self-hosted/local-source-code)
## 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](https://docs.dify.ai/getting-started/readme/model-providers).
**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**: Autonomous agents with a sandbox of their own: they run commands, install software, and handle files to get open-ended tasks done. Describe the agent you want and it builds itself. Give it skills, connect tools from [Dify Marketplace](https://marketplace.dify.ai/?category=tool), MCP servers, or your own APIs, and put it to work as a chat app or as a step in any workflow.
**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.
