In their own words
eXist-db
eXist-db is a free, open-source NoSQL document database and application platform centered on XML. Its native engine stores textual or binary documents without requiring a database schema, and it is designed for self-hosted deployment on Linux, macOS, or Windows. The product implements XQuery 3.1, though some features and functions are unsupported, and RESTXQ lets developers deploy RESTful services from XQuery annotations. Its interfaces include REST-style HTTP, SOAP, XML-RPC, and WebDAV. A browser-based IDE provides syntax coloring, code completion, and error checking for application artifacts. Full-text search uses an implementation-specific Apache Lucene approach rather than the W3C XQuery and XPath Full Text 3.0 specification. Security extends Unix permissions with access control lists and external authentication realms. The software is licensed under the LGPL for academic, non-commercial, and commercial use. The documentation lists Java 8 for versions 3.x–6.x or Java 21 for version 7.x, about 500 MB of disk space, and at least 512 MB of memory.
JasDB
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. Oberasoftware describes the database as useful for quickly prototyping applications and accepts questions or assistance requests through its website.
