Deploy and Host Neo4j on Railway

Neo4j is a graph database that stores data as nodes and relationships and is queried with Cypher.

About Hosting Neo4j

This template runs the official neo4j:5-community image with a persistent volume at /data and modest memory settings (1 GB heap, 512 MB page cache). The login is neo4j with a random password generated into the NEO4J_AUTH variable (format neo4j/): read it in the Variables tab. The public URL serves the HTTP API on port 7474, for example POST /db/neo4j/tx/commit with basic auth. The Bolt protocol is not exposed publicly.

Common Use Cases

Knowledge graphs and recommendation engines
Fraud and network analysis
Backend for GraphRAG and agent memory over HTTP

Dependencies for Neo4j Hosting

Why Deploy Neo4j on Railway?

Railway gives you a public HTTPS URL, persistent storage where needed and automatic restarts with no server to maintain. Use the generated password in the NEO4J_AUTH variable to authenticate.
