StepZen (acquired by IBM) auto-generates GraphQL APIs from REST endpoints, databases, and other sources. Declarative approach to API composition.
Reviewer scorecard
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“IBM acquisition slowed development. The auto-generation from REST to GraphQL was interesting but the market moved on.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“GraphQL-as-a-service is a solution looking for a larger market. Most teams that want GraphQL can build it.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
“API composition will be important but AI-powered approaches may replace declarative GraphQL generation.”
