What SurrealDB is

SurrealDB is a database platform with relational, document, graph, vector, and time-series data as native models. Its SurrealQL language combines SQL with knowledge graph, vector and full-text search, temporal, and key-value queries. Multiple data types can be handled in one ACID transaction, and live queries and change streams let clients see writes as they commit. Deployment options include managed Cloud, embedded and edge options, and self-hosted Enterprise deployments. Cloud includes team collaboration, access management, centralized compliance, encryption in transit and at rest, and listed certifications including SOC 2 Type 2, ISO 27001, and Cyber Essentials Plus. Permissions can be applied at role, record, field, table, document, and hierarchical user levels. The first instance includes 1GB of storage free forever, with 0.25 vCPU and 1GB memory in the free configuration. Start is usage-based, with further instances starting at $0.021/hr. Scale has a three-node minimum; Enterprise pricing is custom. SurrealDB reports 4M+ worldwide developers and names Samsung, Nvidia, Verizon, Tencent, and Walmart among users.
