MongoDB vs Neo4j: What are the differences?
What is MongoDB? The database for giant ideas. MongoDB stores data in JSON-like documents that can vary in structure, offering a dynamic, flexible schema. MongoDB was also designed for high availability and scalability, with built-in replication and auto-sharding.
What is Neo4j? The world’s leading Graph Database. Neo4j stores data in nodes connected by directed, typed relationships with properties on both, also known as a Property Graph. It is a high performance graph store with all the features expected of a mature and robust database, like a friendly query language and ACID transactions.
MongoDB belongs to "Databases" category of the tech stack, while Neo4j can be primarily classified under "Graph Databases".
"Document-oriented storage" is the primary reason why developers consider MongoDB over the competitors, whereas "Cypher – graph query language" was stated as the key factor in picking Neo4j.
MongoDB and Neo4j are both open source tools. It seems that MongoDB with 16.2K GitHub stars and 4.08K forks on GitHub has more adoption than Neo4j with 6.56K GitHub stars and 1.62K GitHub forks.
Lyft, MIT, and Bodybuilding.com are some of the popular companies that use MongoDB, whereas Neo4j is used by Movielala, Hinge, and Sportsy. MongoDB has a broader approval, being mentioned in 2175 company stacks & 2143 developers stacks; compared to Neo4j, which is listed in 114 company stacks and 47 developer stacks.
