What is Neo4j ?

Uncompromised Performance, Reliability, and Integrity

The creator and leader of the graph database category, Neo4j continues to expand the limits of graph technology, helping empower the largest active community of 220,000 developers, data scientists, and architects who are working to solve the world's most complex and valuable data problems.

Revealing Richer Context to Drive Deeper Insights

Analysts and data scientists can incorporate network structures to infer meaning, increase ML accuracy, and drive contextual AI – making better predictions with the data they already have. Neo4j is fueled by our vast, production-ready algorithm library and advanced, groundbreaking machine learning workflows not found anywhere else.

The Most Trusted. The Most Secure. The Most Deployed.

Neo4j is the only enterprise-strength graph database that combines native graph storage, advanced security, scalable speed-optimized architecture, and ACID compliance to ensure predictability and integrity of relationship-based queries. That’s why it’s deployed by hundreds of Fortune 500 companies, government agencies, and NGOs.

No More Complex Joins

Cypher is a powerful, intuitive, graph-optimized query language that understands, and takes advantage of, data connections. It’s user-friendly, easy to learn, and follows connections – in any direction – to reveal previously unknown relationships and clusters. When trying to find patterns or insights within data, Cypher queries are much simpler and easier to write than massive SQL joins. Since Neo4j doesn’t have tables, there are no joins to worry about. Compare the Cypher query at the left with its equivalent in SQL.

Use Your Favorite Programming Languages

We aim to make the Neo4j experience fast, natural, and fun for developers. Neo4j supports GraphQL and drivers for .Net, Java, Node.js, Python, and more. Our community of contributors provide many more drivers, including PHP, Ruby, R, Erlang, and Clojure.

Helpful Tools for Modern App & Web Development

Neo4j provides an array of tools, libraries, and frameworks to make development faster and easier. Developer tools like Neo4j Desktop, Browser, and Sandbox make it simple to learn and develop graph apps. The new Neo4j GraphQL Library translates GraphQL queries into Cypher, making it easier for GraphQL users to use Neo4j. It also streamlines integration of Neo4j with React, Vue, and other open source frameworks.
