Context, made atomic

Documents, graphs, vectors, time-series, and relational data as native primitives in a single ACID transaction. No plugins, no bolt-ons, no frankenstack.

Get started Try SurrealDB

Native multi-model engine

Documents, graphs, vectors, full-text search, time-series, and relational data - fully unified in one database and query language. No plugins or bolt-ons.

03 |HOW SURREALDB COMPARES

Every other agent stack is a frankenstack

Document store, graph database, vector database, cache, message broker, memory middleware - glued together and prayed over. SurrealDB replaces all of it.

vs. Postgres

Postgres bolts on vectors with pgvector and graphs with recursive CTEs. SurrealDB makes every model native - no extensions, no workarounds.

Compare with Postgres

vs. MongoDB

MongoDB is a document store. Graph traversal, vector search, and temporal queries require separate systems. SurrealDB unifies them.

Compare with MongoDB

vs. Neo4j

Neo4j is a graph database. Documents, vectors, and time-series require separate infrastructure. SurrealDB does it all in one engine.

Compare with Neo4j

vs. Vector databases

Pinecone, Chroma, and Weaviate store embeddings. SurrealDB stores embeddings alongside their entities, relationships, and temporal context.

Compare with vector databases

vs. Memory middleware

Mem0 layers memory on top of fragmented databases. Spectron builds memory directly into SurrealDB - one transaction, no consistency gaps.

Compare with memory middleware

vs. Agent databases

HelixDB and HydraDB internalise a frankenstack. SurrealDB provides true multi-model unification with ACID across all data types.

Compare with agent databases
