Overview
ArcadeDB is an ACID database written in Java that stores graph, document, key/value, time series, vector and geospatial data in one engine. It accepts SQL, Cypher, Gremlin, GraphQL and MongoDB queries, and is reachable over HTTP/JSON, the Postgres wire protocol, and subsets of the Redis and MongoDB protocols. It also ships a built-in MCP server and a Claude Code plugin.
Who it is for: Engineers needing one self-hosted database for graph, document and vector data
Strengths
- One engine covers graph, document, key/value, time series, vector and geospatial models
- Many query languages and protocols: SQL, Cypher, Gremlin, GraphQL, Postgres wire, HTTP/JSON
- Built-in MCP server plus a Claude Code plugin for AI assistant access
- Runs embedded on the JVM, as a server, or as an experimental native image
Weaknesses
- Redis and MongoDB drivers implement only a subset of operations
- Requires Java 21+; Java 17 is supported only on a separate branch
- GraalVM native-image build is labeled experimental
- Studio AI assistant is marked Beta
What it needs
- no GPU
- Compose
- Needs Java 21+
- port 2480
