StepZen (acquired by IBM) auto-generates GraphQL APIs from REST endpoints, databases, and other sources. Declarative approach to API composition.
Reviewer scorecard
“At $500/mo it needs to replace at least 10 hours of developer time per month. In my testing, I spent more time reviewing and fixing its output than I saved. Not there yet.”
“IBM acquisition slowed development. The auto-generation from REST to GraphQL was interesting but the market moved on.”
“The marketing writes checks the product can't cash. 'Autonomous software engineer' implies reliability that doesn't exist. It's a talented intern that needs constant supervision.”
“GraphQL-as-a-service is a solution looking for a larger market. Most teams that want GraphQL can build it.”
“Devin is early but directionally correct. The autonomous agent approach will win eventually. Cognition has the best shot at getting there first. Invest in the future, not the present.”
“API composition will be important but AI-powered approaches may replace declarative GraphQL generation.”
