Multi-model database combining documents, graphs, vectors and time-series
Overview
SurrealDB is a unified, multi-model database platform that manages documents, graphs, vectors and time-series data in a single ACID-compliant engine. Founded in 2022, it positions itself as a data platform for AI applications, offering an agent memory layer with entity extraction, knowledge graph construction and hybrid retrieval. It is available as SurrealDB Cloud or self-hosted Enterprise deployments, and holds SOC 2 Type 2, ISO 27001, GDPR and Cyber Essentials Plus certifications.
The honest half
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about SurrealDB.
Cross-shopped
Each pairing was judged by two reviewers asking whether a buyer would genuinely weigh the two against each other. The ones that failed were deleted rather than published.

Softwr does not host reviews and shows no star rating for SurrealDB, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it. Tell us if any of it is wrong.
