Trusted by enterprises like PolyAI, SurrealDB is SOC 2 Type 2, GDPR, and Cyber Essentials Plus certified. Start building today with a simple curl install or explore the cloud for high availability and scale.
Core Features
Multi-model Database
Combines documents, graphs, vectors, time-series, and memory into one database with a single query language, reducing complexity and data duplication.
ACID Compliance
Provides atomicity, consistency, isolation, and durability guarantees for multi-table and multi-row transactions, ensuring data integrity.
Horizontal Scalability
Scales horizontally with storage-compute separation, automatic sharding, and multi-region replication to handle petabytes of data and high concurrency.
Vector and Full-Text Search
Supports HNSW vector indexing, full-text search with BM25 ranking, and hybrid search (reciprocal rank fusion) for advanced AI and retrieval applications.
AI Agent Context Layer
Provides unified memory, RAG, Graph RAG, MCP integration, and live reactivity for building reliable production-scale AI agents.
WebAssembly Extensibility
Allows custom extensions written in Rust to run securely inside the database with near-native performance and shared ACID transactions.
Granular Security & Permissions
Offers role-based, field-level, and record-level access control, with support for third-party OAuth, encryption at rest and in transit, and audit logging.
Multiple SDKs and Deployment Options
Includes server-side and client-side SDKs for Python, JavaScript, Rust, Go, Java, .NET, PHP, C, and more; deploys as cloud, self-hosted, edge, or embedded.

Pros and Cons
Pros
- Unified Data ModelCombines documents, graphs, vectors, time-series, and memory into one system, eliminating the need for multiple databases and ETL pipelines.
- Strong ACID GuaranteesProvides full ACID compliance across multi-table transactions, ensuring data consistency and reliability for critical workloads.
- Designed for AI AgentsBuilt-in support for vector search, RAG, Graph RAG, MCP, and live reactivity makes it ideal for production-scale AI applications.
- Horizontal ScalabilitySeparation of compute and storage, automatic sharding, and multi-region replication enable scaling from prototype to enterprise without manual partitioning.
- Rich Security FeaturesIncludes role-based, field-level, and record-level access control, encryption at rest and in transit, audit logging, and compliance certifications (SOC 2, ISO 27001, GDPR).
Cons
- Learning CurveSurrealQL and the multi-model approach may require upfront learning for teams accustomed to traditional relational or NoSQL databases.
- Ecosystem MaturitySome advanced features (e.g., HIPAA compliance, BI tool integrations, incremental backups) are marked as 'Future' or 'In Development', indicating an evolving platform.
- Pricing for ScaleWhile the Start plan is affordable, Scale and Enterprise plans can become expensive for large deployments, especially with many nodes.
- Limited Third-Party ORM SupportORMs for Python, Go, and other languages are listed as 'Future', requiring custom integration or reliance on the low-level SDKs for now.
- Relatively New EcosystemAs a younger database, community resources, tutorials, and third-party tooling may be less extensive compared to established databases like PostgreSQL or MongoDB.
