SurrealDB

Deploy SurrealDB on Out Plane — a multi-model database that combines relational tables, document collections, graph relationships, and vector search into a single database engine. SurrealDB uses SurrealQL, an SQL-like query language extended with graph traversals, record links, and embedded functions.

SurrealDB includes built-in authentication, real-time change feeds over WebSocket, schema-full and schema-less modes, and support for geospatial queries. The HTTP and WebSocket APIs make it suitable for both server-side and client-side applications. Self-hosting on Out Plane provides a single database solution that replaces multiple specialized engines.

Ideal for applications that need flexible data modeling, social networks with graph relationships, real-time collaborative tools, and any project that benefits from combining relational, document, and graph queries in a single database.
