Deploy MongoDB with UI

Deploy and Host MongoDB with UI on Railway

MongoDB with UI combines a persistent MongoDB database with Mongo Express, a lightweight web-based administration interface. The template gives you both direct database access and a visual browser for inspecting collections, documents, indexes, and database structure from your browser.

About Hosting MongoDB with UI

This template deploys two connected services:

• MongoDB — the persistent document database
• Mongo Express — the browser-based MongoDB management interface

Mongo Express connects to MongoDB through Railway's private network, keeping internal database traffic inside the project.

MongoDB also uses Railway TCP Networking so external clients such as MongoDB Compass, local applications, development tools, or remote servers can connect when needed.

A persistent volume mounted to MongoDB keeps your database files available across restarts and redeployments.

Common Use Cases

• Run a self-hosted MongoDB database
• Browse collections and documents visually
• Manage MongoDB without relying exclusively on the CLI
• Inspect application data during development
• Connect MongoDB Compass from your local machine
• Provide MongoDB to applications running inside Railway
• Access the same database from external services
• Debug document structures and application data
• Manage indexes and collections from a browser
• Build development and testing database environments

MongoDB with UI vs MongoDB Alone

This template is useful when you want the simplicity of a standalone MongoDB database while also having an immediately available administration interface.

Persistent Storage

MongoDB stores its database files in:

/data/db

The MongoDB service uses a persistent Railway volume at this location.

Persistent storage protects:

• Databases
• Collections
• Documents
• Indexes
• MongoDB metadata

Mongo Express does not contain the actual database data; it connects to the MongoDB service and provides a visual management layer.

Private and External Connectivity

This template provides two ways to connect to MongoDB.

Railway Private Network

Applications running inside the same Railway project should use the private MongoDB connection.

This includes Mongo Express itself.

Private networking keeps traffic inside Railway and avoids routing internal database connections through the public TCP proxy.

External TCP Access

Railway TCP Networking is enabled on the MongoDB service so the database can also be accessed externally.

This is useful for:

• MongoDB Compass
• Local development
• External APIs
• VPS-hosted applications
• Remote database tools

Use the public MongoDB connection information exposed by the MongoDB service when connecting from outside Railway.

Getting Started

After deployment:

1. Wait until both MongoDB and Mongo Express are online.
2. Open the public Railway URL assigned to Mongo Express.
3. Sign in using the credentials configured before deployment.
4. Browse your MongoDB databases and collections.
5. Create, inspect, update, or remove documents as needed.

Before deploying the template, provide:

ME_CONFIG_BASICAUTH_USERNAME
ME_CONFIG_BASICAUTH_PASSWORD

These credentials protect access to the Mongo Express web interface.

Connecting with MongoDB Compass

To connect from MongoDB Compass or another external MongoDB client:

1. Open the MongoDB service in Railway.
2. Find the public TCP connection information.
3. Copy the public MongoDB connection URI.
4. Paste it into MongoDB Compass.
5. Connect using the generated MongoDB credentials.

External clients use Railway's TCP Proxy, while internal services should continue using Railway private networking.

Security Considerations

Mongo Express provides administrative access to your MongoDB instance, so its login credentials should be treated as sensitive.

For production or sensitive data:

• Use a strong Mongo Express username and password.
• Keep application-to-database traffic on Railway private networking.
• Only use TCP access when external database connectivity is required.
• Protect MongoDB root credentials.
• Avoid sharing public database connection strings.
• Rotate credentials if they are exposed.
• Back up important MongoDB data.

Why Deploy MongoDB with UI on Railway?

Railway is a singular platform to deploy your infrastructure stack. Railway will host your infrastructure so you don't have to deal with configuration, while allowing you to vertically and horizontally scale it.

By deploying MongoDB with UI on Railway, you get a persistent document database, browser-based administration interface, private service networking, and optional external TCP access in one simple deployment.
