Deploy and Host Mermify on Railway

Mermify is a free, open-source visual editor for Mermaid.js flowcharts and sequence diagrams. It combines a Monaco code editor with an interactive drag-and-drop canvas, enabling real-time, bi-directional synchronization between Mermaid source code and visual diagrams while supporting high-quality exports and modern editing tools.

About Hosting Mermify

Hosting Mermify on Railway provides a simple way to deploy the Vite-powered web application without managing infrastructure. Railway automatically builds the project from the repository and serves it over HTTPS with a public domain or your own custom domain. Since Mermify is a browser-based application that performs diagram editing entirely on the client side, it does not require a database or persistent server storage. Railway handles deployments, networking, and scaling, allowing you to publish updates with minimal operational overhead while providing users with a fast, responsive diagram editor accessible from anywhere.

Common Use Cases

• Create and edit Mermaid flowcharts with a visual drag-and-drop interface.
• Build and maintain sequence diagrams with synchronized visual and code editing.
• Self-host an interactive Mermaid editor for development teams, documentation portals, or educational environments.

Implementation Details

Mermify is a static frontend application built with Vite, React, and TypeScript. Railway automatically builds the project from the repository and serves the generated application.
