JasDB

What JasDB is
JasDB is a free, self-hosted document database intended for application prototyping and embedded use, including on Android phones and tablets. It works with JSON documents and can be embedded in software or scaled out. Developers can use Java and REST APIs, and a Java/JVM entity-mapping solution is available. Its REST interface supports querying and changing data, while the maker describes its query engine as offering full query capabilities. Access controls include users and security groups, with OAuth available through the REST interface. To start, unpack the download, run start.bat on Windows or start.sh on a shell, then open http://localhost:7050. The maker has also announced a Docker container. JasDB is available for Android, Linux, macOS, and Windows. It is released under the MIT X11 License, which requires redistribution to be free of charges or fees to recipients; the license also provides the software as-is without warranty. Oberasoftware presents it as useful for quickly prototyping applications.
