Surrealdb

SurrealDB is an AI-native, multi-model database built in Rust designed to unify multiple data models into a single, powerful engine. It combines document, graph, relational, time-series, geospatial and key-value data types natively, with powerful search and retrieval (vectors, full-text, hybrid) and built-in real-time and event-driven capabilities. By using SurrealDB, companies can drastically simplify their tech stack, reduce complexity and operational overhead, and build new applications faster. SurrealDB is designed as a single data and logic layer for AI agents, knowledge graphs, real-time applications (e.g. recommendation engines, fraud detection systems), and OLTP applications requiring multiple data types. SurrealDB can also be used as a backend-as-a-service thanks to its support for direct user authentication. Given that it’s a single Rust binary, SurrealDB can run embedded, in the edge, as single backend node, or fully scaled to a distributed cluster - all with the same API.
