Summary

ArcadeDB is an open-source database that stores graph, document, key-value, full-text search, vector, and time-series data in one engine. The database is free for any use under the Apache 2.0 license, with no usage limits or feature restrictions, and it states that it supports full ACID transactions in single-node and distributed deployments. Developers can query it with SQL, OpenCypher 25, Gremlin, GraphQL, MongoDB query language, or a native Java API. It can run embedded in 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 support Neo4j and OrientDB; the maker says Raft consensus maintains consistency across multiple servers. The Community plan includes forums, GitHub Issues, public documentation, and tutorials. Paid support starts at $299.00 USD per month per server, with response targets and coverage varying by plan. A separate Studio AI Assistant license is listed at $19.99 USD per month.
