SurrealDB

SurrealDB is a Rust multi-model database and context layer for AI agents: documents, graphs, vectors, time-series, and relations are native in one ACID engine, no stitched stores. Query with SurrealQL, connect via MCP, WebSocket, and SDKs, with GraphQL generated from your schema. Built-in auth, permissions, HTTP APIs, and live queries reduce separate backend glue. Runs embedded, at the edge, or as a highly-scalable cluster in the cloud. Same engine, everywhere.
