SurrealDB

SurrealDB belongs in the catalog because it represents a different database design philosophy than the usual one-engine-per-problem approach. The official product story combines document, graph, relational, and realtime concepts in one platform, which makes it attractive to teams that want to simplify architecture without flattening their data model into the least expressive option. That positioning is especially relevant for modern apps, AI products, and event-rich systems that straddle multiple data access patterns.

It also deserves inclusion because the commercial posture is legible even when not every production scenario is reduced to one public number. SurrealDB openly frames pricing around Cloud, Self-Hosted, and Enterprise, and the pricing page explicitly says buyers can compare options from free tiers to dedicated support. That is enough to model the platform honestly: there is a meaningful free path, and there are clearer premium deployment and support tracks for teams graduating into production scale.
