In their own words
ArcadeDB
ArcadeDB is an open-source database engine that stores graph, document, key-value, full-text search, vector, and time-series data together. The database is free for any use under the Apache 2.0 license, with no usage limits or feature restrictions, and states that it provides full ACID transactions on single-node and distributed deployments. Query options include SQL, OpenCypher 25, Gremlin, GraphQL, MongoDB query language, and a native Java API. ArcadeDB can run inside Java applications or as a standalone server, with installation options including Docker, a GitHub binary, Maven, and Kubernetes. ArcadeDB Server supports HTTP/JSON and compatibility with Postgres wire protocol, Redis, and MongoDB protocols. Built-in importers cover Neo4j and OrientDB, and the maker says Raft consensus maintains consistency across multiple servers. The Community plan is free forever and includes forums, GitHub Issues, documentation, and tutorials. Paid support starts at $299 a month per server, with response targets and coverage varying by plan. A separate Studio AI Assistant license costs $19.99 a month.
Eclipse RDF4J
Eclipse RDF4J is a modular Java framework for parsing, storing, querying, and reasoning over RDF data. It supports SPARQL 1.1 query and update, and its API can access remote RDF repositories in the same way as local ones. Supported formats include RDF/XML, Turtle, N-Triples, N-Quads, JSON-LD, TriG, and TriX. Storage options include a transactional in-memory store with optional disk persistence and a transactional Native Store aimed at medium-sized datasets around 100 million triples. Extensions add full-text search, RDFS inferencing, rule-based reasoning, SHACL and SPIN validation, and geospatial queries. The SDK bundles libraries, Server, Workbench, Console, and Javadoc API; Workbench includes a web interface with a SPARQL editor. Developers can use Maven artifacts or download an SDK zip or onejar. RDF4J is free under the Eclipse Distribution License, version 1.0. The latest stable release, 6.1.0, requires Java 25 or newer. The project describes its core databases as mainly intended for small to medium-sized datasets and notes third-party stores may scale further or offer additional features.
