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.
