ArangoDB

Multi-model database supporting graphs, documents, and vectors with a unified AQL query language.

Overview

ArangoDB is a flexible NoSQL database that natively handles graph traversal, document storage, and key-value lookups within a single engine. Its recent vector search capabilities enable hybrid retrieval patterns without external dependencies, while AQL provides a consistent syntax across all data models. The platform includes a free community tier and cloud sandbox for rapid prototyping.
