StepZen (acquired by IBM) auto-generates GraphQL APIs from REST endpoints, databases, and other sources. Declarative approach to API composition.
Reviewer scorecard
“The REST API description standard. Every API should have an OpenAPI spec. The tooling ecosystem is massive.”
“IBM acquisition slowed development. The auto-generation from REST to GraphQL was interesting but the market moved on.”
“OpenAPI specs are documentation, testing, and client generation in one file. Non-negotiable for REST APIs.”
“GraphQL-as-a-service is a solution looking for a larger market. Most teams that want GraphQL can build it.”
“OpenAPI specs are increasingly important as AI tools consume APIs. Machine-readable API descriptions enable AI integration.”
“API composition will be important but AI-powered approaches may replace declarative GraphQL generation.”
