Getting Started

Use Free Gemini (recommend)

1. Get Gemini API Key

2. One-click deployment of the project, you can choose to deploy to Vercel or Cloudflare Currently the project supports deployment to Cloudflare, but you need to follow How to deploy to Cloudflare Pages to do it.

3. Start using

Use Other LLM

1. Deploy the project to Vercel or Cloudflare
2. Set the LLM API key
3. Set the LLM API base URL (optional)
4. Start using

⌨️ Development

Follow these steps to get Deep Research up and running on your local browser.

Prerequisites

• Node.js (version 18.18.0 or later recommended)
• pnpm or npm or yarn

Installation

1. Clone the repository:

   git clone https://github.com/u14app/deep-research.git
   cd deep-research
   

2. Install dependencies:

   pnpm install  # or npm install or yarn install
   

3. Set up Environment Variables:

   You need to modify the file env.tpl to .env, or create a .env file and write the variables to this file.

   # For Development
   cp env.tpl .env.local
   # For Production
   cp env.tpl .env
   

4. Run the development server:

   pnpm dev  # or npm run dev or yarn dev
   

   Open your browser and visit http://localhost:3000 to access Deep Research.

Custom Model List

The project allow custom model list, but only works in proxy mode. Please add an environment variable named NEXT_PUBLIC_MODEL_LIST in the .env file or environment variables page.

Custom model lists use , to separate multiple models. If you want to disable a model, use the - symbol followed by the model name, i.e. -existing-model-name. To only allow the specified model to be available, use -all,+new-model-name.

Deployment

Vercel

Cloudflare

Currently the project supports deployment to Cloudflare, but you need to follow How to deploy to Cloudflare Pages to do it.

Docker

The Docker version needs to be 20 or above, otherwise it will prompt that the image cannot be found.

⚠️ Note: Most of the time, the docker version will lag behind the latest version by 1 to 2 days, so the "update exists" prompt will continue to appear after deployment, which is normal.

docker pull xiangfa/deep-research:latest
docker run -d --name deep-research -p 3333:3000 xiangfa/deep-research

You can also specify additional environment variables:

docker run -d --name deep-research \
   -p 3333:3000 \
   -e ACCESS_PASSWORD=your-password \
   -e GOOGLE_GENERATIVE_AI_API_KEY=AIzaSy... \
   xiangfa/deep-research

or build your own docker image:

docker build -t deep-research .
docker run -d --name deep-research -p 3333:3000 deep-research

If you need to specify other environment variables, please add -e key=value to the above command to specify it.

Deploy using docker-compose.yml:

version: '3.9'
services:
   deep-research:
      image: xiangfa/deep-research
      container_name: deep-research
      environment:
         - ACCESS_PASSWORD=your-password
         - GOOGLE_GENERATIVE_AI_API_KEY=AIzaSy...
      ports:
         - 3333:3000

or build your own docker compose:

docker compose -f docker-compose.yml build

Static Deployment

You can also build a static page version directly, and then upload all files in the out directory to any website service that supports static pages, such as Github Page, Cloudflare, Vercel, etc..

pnpm build:export

⚙️ Configuration

As mentioned in the "Getting Started" section, Deep Research utilizes the following environment variables for server-side API configurations:

Please refer to the file env.tpl for all available environment variables.

Important Notes on Environment Variables:

• Privacy Reminder: These environment variables are primarily used for server-side API calls. When using the local API mode, no API keys or server-side configurations are needed, further enhancing your privacy.

• Multi-key Support: Supports multiple keys, each key is separated by ,, i.e. key1,key2,key3.

• Security Setting: By setting ACCESS_PASSWORD, you can better protect the security of the server API.

• Make variables effective: After adding or modifying this environment variable, please redeploy the project for the changes to take effect.

API documentation

Currently the project supports two forms of API: Server-Sent Events (SSE) and Model Context Protocol (MCP).

Server-Sent Events API

The Deep Research API provides a real-time interface for initiating and monitoring complex research tasks.

Recommended to use the API via @microsoft/fetch-event-source, to get the final report, you need to listen to the message event, the data will be returned in the form of a text stream.

POST method

Endpoint: /api/sse

Method: POST

Body:

…

Headers:

interface Headers {
  "Content-Type": "application/json";
  // If you set an access password
  // Authorization: "Bearer YOUR_ACCESS_PASSWORD";
}

See the detailed API documentation.

GET method

This is an interesting implementation. You can watch the whole process of deep research directly through the URL just like watching a video.

You can access the deep research report via the following link:

http://localhost:3000/api/sse/live?query=AI+trends+for+this+year&provider=pollinations&thinkingModel=openai&taskModel=openai-fast&searchProvider=searxng

Query Params:

// The parameters are the same as POST parameters
interface QueryParams extends SSEConfig {
  // If you set the `ACCESS_PASSWORD` environment variable, this parameter is required
  password?: string;
}

Model Context Protocol (MCP) Server

Currently supports StreamableHTTP and SSE Server Transport.

StreamableHTTP server endpoint: /api/mcp, transport type: streamable-http

SSE server endpoint: /api/mcp/sse, transport type: sse

{
  "mcpServers": {
    "deep-research": {
      "url": "http://127.0.0.1:3000/api/mcp",
      "transportType": "streamable-http",
      "timeout": 600
    }
  }
}

Note: Since deep research take a long time to execute, you need to set a longer timeout to avoid interrupting the study.

If your server sets ACCESS_PASSWORD, the MCP service will be protected and you need to add additional headers parameters:

{
  "mcpServers": {
    "deep-research": {
      "url": "http://127.0.0.1:3000/api/mcp",
      "transportType": "streamable-http",
      "timeout": 600,
      "headers": {
        "Authorization": "Bearer YOUR_ACCESS_PASSWORD"
      }
    }
  }
}

Enabling MCP service requires setting global environment variables:

…

Note: To ensure that the MCP service can be used normally, you need to set the environment variables of the corresponding model and search engine. For specific environment variable parameters, please refer to env.tpl.

How it works

FAQs

Why does my Ollama or SearXNG not work properly and displays the error TypeError: Failed to fetch?

If your request generates CORS due to browser security restrictions, you need to configure parameters for Ollama or SearXNG to allow cross-domain requests. You can also consider using the server proxy mode, which is a backend server that makes requests, which can effectively avoid
