ArcadeDB

ArcadeDB is an open-source, Apache 2.0 licensed database developed by Arcade Data Ltd. Its core proposition is native multi-model storage: graphs, documents, key-value pairs, BM25-ranked full-text search, vectors, and time-series all live in one engine, so teams avoid stitching together separate systems for each data shape.

The engine emphasizes performance and correctness, claiming over 10 million records per second with full ACID compliance, and it publishes benchmarks and Jepsen testing results to back reliability and high-availability claims. Query support spans SQL, OpenCypher, Gremlin, GraphQL, and the MongoDB query protocol, and ArcadeDB Studio provides a visual interface for exploring and managing data.

Deployment options include embedded Java and Python, client/server, Docker, Helm, and Maven, with drivers and integrations for common languages. Documented migration paths from Neo4j and OrientDB lower switching costs, and MCP and AI agent integrations position the database as a context layer for AI applications.

Typical use cases include Graph RAG, fraud detection, recommendation engines, knowledge graphs, real-time analytics, Customer 360, AI/ML feature stores, supply chain route planning, and identity and access management. Developers can start with the documentation, academy, and query cheat sheet, then choose embedded or client/server mode based on workload.
