What is objectbox-java?

ObjectBox Java is a high-performance, lightweight on-device database and vector database specifically designed for Java and Kotlin applications. It enables efficient data storage and management within Android and JVM environments, including Linux, macOS, and Windows. A key differentiator is its first-on-device vector database capability, allowing for fast vector search to power RAG AI, generative AI, and similarity search applications. ObjectBox boasts exceptional speed, outperforming alternatives like SQLite and Realm in CRUD operations, while maintaining minimal CPU, power, and memory consumption. It simplifies development with a concise, language-native API that eliminates complex SQL queries, supports plain objects (POJOs) with built-in relations, and offers automatic schema migrations.
