Deploy and Host DeerFlow on Railway

DeerFlow (Deep Exploration and Efficient Research Flow) is a community-driven deep research framework that integrates language models with web search, retrieval, code execution, and collaborative tools. It enables users to perform AI-powered investigations, generate structured research reports, and even create podcasts or presentations from findings, all in one streamlined workflow.

About Hosting DeerFlow

Hosting DeerFlow on Railway provides a one-click way to set up and run the complete deep research system without manual installation. This template includes a Python backend, a Node.js web UI, and a managed Postgres database for storing research results. With built-in support for Google AI Studio (Gemini models) and Tavily Search APIs, you only need to set your API keys—Railway takes care of infrastructure, scaling, and persistence. Within minutes, you’ll have a fully operational research assistant that can search the web, integrate with external tools, and generate AI-enhanced reports, audio, or presentations.
