Deploy and Host Next AI Draw.io on Railway

About Hosting

Next AI Draw.io is a Next.js-based AI diagram tool that integrates natural language prompting with draw.io rendering. It can generate and edit diagrams from text, image, PDF, and other inputs, then render directly in an interactive browser canvas.

This Railway template deploys the official upstream container image ghcr.io/dayuanjiang/next-ai-draw-io:latest as a single web service. The app listens on port 3000, and Railway routes your public domain to that port.

Why Deploy

Fast one-service deployment with the official upstream image.
Multi-provider AI support (OpenAI, Anthropic, Gemini, DeepSeek, OpenRouter, Bedrock, and more).
No external database required for core functionality.
Easy migration from local Docker setup to production on Railway.
Works with your own model API keys and custom provider endpoints.

Common Use Cases

Build architecture diagrams from natural language prompts.
Convert existing image/PDF/text inputs into editable draw.io diagrams.
Host a private internal diagram assistant for teams.
Run a self-hosted alternative to SaaS diagram copilots.
