Comparison

Neo4j vs ArangoDB

Overview

The world's leading graph database platform.

Neo4j is the most widely adopted graph database, storing data as nodes and relationships for fast traversal of connected data. It uses the Cypher query language and powers knowledge graphs, fraud detection, recommendations and GraphRAG, with a managed Aura cloud service.

ArangoDB

One database for graph, document and key-value data.

ArangoDB is an open-source multi-model database that combines graph, document and key-value data in a single engine with one query language (AQL). It lets teams model connected and document data together without stitching multiple databases.

Which should you choose?

Neo4j is the market-leading native graph database, with Cypher, a Graph Data Science library, and GraphRAG support, freemium via Aura. ArangoDB is multi-model — graph, document, and key-value in one engine with a unified AQL query language — also open-source and freemium via ArangoGraph. Choose Neo4j if you want the most mature, purpose-built graph engine and ecosystem; choose ArangoDB if you want graph plus document/key-value data in a single database.

TLDR

—If you want the most mature, purpose-built graph database and ecosystem, choose Neo4j.
—If you want graph plus document and key-value data in a single database, choose ArangoDB.
