FusionDB is a multi-model database from Evolved Binary Ltd, positioned for NoSQL, XML, binary documents, and Key/Value storage. The page clearly states that it is currently in Alpha. It can use XQuery to store, manage, and query millions of documents and key-value pairs, and it emphasizes 100% compatibility with the eXist-db API. Native querying for JSON, HTML, and Markdown is planned for the future, but these capabilities are not available yet.
In terms of functionality, FusionDB’s most notable value today is the combination of an XML/document database with Key/Value storage, making it worth evaluating for developers already using XQuery or the eXist-db ecosystem. For language and framework support, the text only confirms compatibility with XQuery and the eXist-db API; there is no information about SDKs for Java, Python, JavaScript, or similar languages. For deployment, the page provides an Alpha download and states that the default ports are HTTP 4059 and HTTPS 5059, suggesting it is geared more toward local or self-hosted installation rather than a cloud database service.
The current Alpha version is offered under a personal, non-transferable, non-exclusive license and is limited to non-commercial use. The official site explicitly states that it is not currently open-source software, while also noting that the team is monitoring licensing issues around open source, Source Available models, cloud providers, and infrastructure software. A future dual-license model combining open-source and commercial licensing may be considered. Commercial pricing, enterprise support, and licensing for a stable release have not yet been disclosed.
Its strengths are a clear positioning, strong relevance for XML/XQuery and eXist-db users, and the availability of an Issue Tracker and email support channels. The drawbacks are also significant: the product is still in Alpha; installation and getting-started videos are marked as coming soon; it is closed source and restricted to non-commercial use; JSON, HTML, and Markdown querying are still only planned; and there is a lack of information on SDKs, ecosystem integrations, performance, security, and production deployment.
FusionDB is better suited for developers doing technical research around database internals, XML document management, or eXist-db migration compatibility. It is not recommended for direct use in production or commercial projects. The page does not provide information about access from China, so this remains unknown; payment methods are also not disclosed. If you need a mature alternative, consider eXist-db, MongoDB, CouchDB, or Redis depending on the use case.
