JasDB is a document-based NoSQL database for rapid application prototyping and embedded use, including on Android phones and tablets. It stores JSON documents and can be embedded in software or scaled out. JasDB provides Java and REST APIs, with an entity-mapping solution for Java and JVM languages. Its REST interface can query and manipulate data, and Oberasoftware describes the query engine as having full query capabilities. Security options include users and groups, with OAuth available through the REST interface. JasDB is self-hosted and available for Android, Linux, macOS, and Windows. To start it, the quick-start instructions say to unzip the download, run start.bat or start.sh, and open http://localhost:7050. Oberasoftware has also announced a Docker container. The software is free and released under the MIT X11 License, with a restriction that redistribution to recipients be free of charges or fees. The license provides the software as-is without warranty.
