StepZen (acquired by IBM) auto-generates GraphQL APIs from REST endpoints, databases, and other sources. Declarative approach to API composition.
Reviewer scorecard
“This is the kind of tool that makes you wonder how you worked without it.”
“GraphQL-as-a-service is a solution looking for a larger market. Most teams that want GraphQL can build it.”
“The free tier is genuinely usable. Rare for this category.”
“IBM acquisition slowed development. The auto-generation from REST to GraphQL was interesting but the market moved on.”
“API composition will be important but AI-powered approaches may replace declarative GraphQL generation.”
