SurrealDB is a multi-model database that handles relational, document, graph, and full-text queries in a single database. Schema-optional, built-in auth, and real-time subscriptions.

SurrealDB consolidates multiple database patterns—relational queries, JSON documents, and graph relationships—in a single engine. Features include real-time live queries via WebSocket, row-level access controls, and API-first architecture. Deployable as managed service or self-hosted. Supports complex transactions and nested data queries without separate microservices.

Pros

Query multiple data models without context-switching between databases
Push real-time data updates to clients via built-in WebSocket support
Define row-level permissions directly in the database schema
Reduce infrastructure complexity with consolidated data layer

Cons

Smaller ecosystem and community compared to PostgreSQL or MongoDB
Learning curve for developers unfamiliar with its query syntax and schema approach
Limited third-party tool integrations for analytics and BI platforms

Best For

Teams building real-time web and mobile applications requiring flexible data models and permission controls without operational complexity of managing multiple databases.
