StepZen (acquired by IBM) auto-generates GraphQL APIs from REST endpoints, databases, and other sources. Declarative approach to API composition.
Reviewer scorecard
“Still the best API development environment. Postbot generating tests from your API schema saves hours. Collections shared across teams are essential.”
“IBM acquisition slowed development. The auto-generation from REST to GraphQL was interesting but the market moved on.”
“It has gotten bloated over the years but the core functionality is unmatched. The AI features are genuinely useful, not just checkbox items.”
“GraphQL-as-a-service is a solution looking for a larger market. Most teams that want GraphQL can build it.”
“In an era of AI agents that can call APIs directly, do we still need a GUI for API testing? The future might be AI testing APIs autonomously.”
“API composition will be important but AI-powered approaches may replace declarative GraphQL generation.”
