A technical review of SpacetimeDB argues its launch benchmarks are dishonest and unfair, while acknowledging the product's unique in-database application server approach.
For engineers evaluating SpacetimeDB, the review warns that the published benchmarks do not reflect real-world performance against comparable systems. The product's architecture, running application code inside the database, differs fundamentally from the distributed databases it benchmarks against, so comparisons are misleading. The review suggests that honest technical documentation and trade-off discussions are more valuable than flashy benchmark claims.

SpacetimeDB's version 2.0 launch included benchmarks that the review calls dishonest and technically flawed.
The product is an all-in-one database and application server, where code runs inside the database, unlike the competitors it benchmarks against.
The review cites examples like PlanetScale and Turbopuffer to argue that honest technical work and clear trade-off documentation are better than unfair benchmark comparisons.
