Structr is a graph application platform that enables the creation of interactive web pages and connect them to web applications, using Neo4j as its underlying database. Structr was developed by Axel Morgner, who chose Neo4j due to its suitability for hierarchical data and embeddability in Java applications. The platform has been used for content management, enterprise data management, and other use cases, offering a flexible graph data model that can store structured and unstructured data. Structr's implementation of the agile-development approach allows for rapid development and testing, with features being implemented within a day. The community and official Neo4j team have been supportive, making it possible for Structr to grow with the market and community.
