ArangoDB vs SurrealDB
Side-by-side comparison of features, pricing, ratings, and alternatives.
ArangoDB is a graph-native, multi-model database that combines graph, document, key-value, vector, and full-text search capabilities in a single system, avoiding the need to stitch together multiple specialized databases. The company has rebranded as Arango and now positions the database as the core of an AI Data Platform aimed at giving enterprise AI agents and applications a unified context layer. ArangoDB is available as a free, open-source Community Edition for evaluation and non-commercial use, with an Enterprise Edition adding high availability, disaster recovery, role-based access control, and lifecycle support. On top of the core database, Arango offers platform features like AutoGraph for automatically building knowledge graphs from existing data, Deep Search for routing queries to the right retrieval strategy, and AQLizer for turning natural-language questions into optimized AQL queries; commercial pricing requires contacting Arango directly.
SurrealDB is a cloud‑native, distributed database that combines the flexibility of NoSQL with the power of SQL‑style querying. It delivers strong ACID guarantees while scaling horizontally for modern applications. Designed for developers and startups, SurrealDB offers seamless integration with popular languages and frameworks, making it easy to embed real‑time data capabilities into web and mobile services.
