ArcadeDB vs FairCom DB

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.

FairCom DB is a multimodel database for developing on-premises applications, combining JSON, key-value, SQL, and ISAM or record-buffer capabilities in one server. Applications can use different models over the same data, query with JSON or standard SQL, and receive query results as JSON. SQL connections are available through JDBC and ODBC, while the built-in API Explorer can help create JSON actions. The database can operate as a traditional server or be embedded in an application. Replication options address high availability and disaster recovery, with ACID compliance or eventual consistency. DB Notify publishes data-change events as JSON messages and integrates with MQTT, AMQP, and Kafka. FairCom DB v13 uses OpenSSL v3 for secure communications and supports X.509 client certificate authentication. File and user security are available only in the client/server operational model. A free Developer’s Edition is limited to development environments and has a three-hour timeout; production licensing requires contacting sales. A free trial is also available, and pricing is on request.
