SurrealDB

SurrealDB is a multi-model database built in Rust designed to unify multiple data models into a single, powerful engine. It combines document, graph, time-series, relational, geospatial and key-value data types with powerful search and retrieval (vector, full-text, hybrid), and real-time and event-driven capabilities, enabling developers to build powerful applications faster and more efficiently. SurrealDB is used for data-intensive use cases such as data layer for AI Agents, knowledge graphs, real-time apps (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‐app), in the browser (via WebAssembly), in the edge, as single backend node, or in a distributed cluster. SurrealDB is one of the fastest growing open-source databases in GitHub and is being used by companies like like Verizon, Samsung and Nvidia in production for large scale deployments. By simplifying the technology stack, SurrealDB allows developers and companies to focus on innovation rather than managing complex integration layers between multiple databases.
