Deploy and Host Memgraph + Memgraph Lab on Railway

Memgraph is an open source, in-memory graph database written in C++: fast, ACID compliant, Cypher and Bolt compatible, with the MAGE library of 300+ graph algorithms included. Memgraph Lab is its visual interface for writing queries, exploring graphs, and monitoring your instance. This template deploys both, wired together and ready to use.

About Hosting Memgraph + Memgraph Lab

You get two services. The database runs the official memgraph/memgraph-mage image, pinned to a specific version, with authentication enabled from the first boot, a persistent volume at /var/lib/memgraph, and a public Bolt endpoint published as BOLT_URL. Memgraph Lab runs on its own public URL, and its connect form comes pre-filled with the database's private network address, so the two talk to each other without leaving Railway. Memory limit and log level are plain environment variables. Plan at least 2 GB of RAM for the database, since Memgraph keeps its working set in memory. Lab itself is lightweight.

Common Use Cases

Interactive graph exploration: a hosted query UI your whole team can open in the browser, no local installs needed
GraphRAG and AI agents: ground LLM answers in a knowledge graph with built-in vector search, and inspect what the agent actually stored using Lab
Real-time recommendations and fraud detection: run multi-hop queries and MAGE algorithms on live data, and visualize the patterns you find
Prototyping graph models: sketch, query, and refine your schema visually before wiring up application code

Dependencies for Memgraph + Memgraph Lab Hosting

None. One click deploys both services with production-ready configuration: pinned official images, generated admin password, persistent volume, public Bolt endpoint, private networking between Lab and the database, and sane memory settings.

Deployment Dependencies

The template itself depends on nothing. These are the docs, SDKs, and tools you will actually use once it is running:

Implementation Details

Signing in to Lab takes about 20 seconds: open the Lab service's public URL, click New connection, and choose Memgraph instance. The host and port are already filled in from the private network. Under Authentication pick Username/password and use MEMGRAPH_USER and MEMGRAPH_PASSWORD from the Memgraph service's variables. Lab cannot log you in automatically because the database requires authentication, which you want, since its Bolt endpoint is public.

Your applications connect with any Neo4j-compatible driver:

from neo4j import GraphDatabase

driver = GraphDatabase.driver(
    "bolt://your-proxy-domain:port",          # BOLT_URL
    auth=("memgraph", "your-password"),       # MEMGRAPH_USER / MEMGRAPH_PASSWORD
)

Good to know:

Lab's live log-streaming tab is not available on Railway, since it needs direct browser access to port 7444. Use Railway's log viewer instead.
MEMGRAPH_USER and MEMGRAPH_PASSWORD only apply on the first boot. To change the password later, run SET PASSWORD TO 'new' in Cypher.
Data persists in the attached volume across restarts, redeploys, and image upgrades.

FAQ

How do I know this template will be maintained?

It is built and maintained by Webified, a software agency. We use this exact setup in commercial projects for paying clients, so we have a direct interest in keeping it healthy. Versions are pinned, and we review new Memgraph releases before bumping them. If you run into anything, ask in the template's support thread on Railway.

Why do I have to type the password into Lab?

Lab's quick connect cannot carry credentials yet (it is an open feature request with the Memgraph team), and the database rightly refuses anonymous connections. The connect form comes pre-filled with the host and port, so it is one paste of the password and you are in.

What happens to my data on restarts, redeploys, or upgrades?

Nothing. Snapshots and write-ahead logs live on the attached Railway volume, which survives all of those. Upgrading means changing the image tag and redeploying. Your data stays where it is.

Why Deploy Memgraph + Memgraph Lab 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 Memgraph + Memgraph Lab on Railway, you are one step closer to supporting a complete full-stack application with minimal burden. Host your servers, databases, AI agents, and more on Railway.
