Reviewer scorecard
“IBM acquisition slowed development. The auto-generation from REST to GraphQL was interesting but the market moved on.”
“The code quality is surprisingly good — real shadcn components, not generic divs with inline styles. Saves me 2-3 hours per UI component.”
“GraphQL-as-a-service is a solution looking for a larger market. Most teams that want GraphQL can build it.”
“Does one thing extremely well: turning ideas into working UI. It won't replace a designer, but it eliminates the blank canvas problem.”
“API composition will be important but AI-powered approaches may replace declarative GraphQL generation.”
“As a creator, I can now prototype landing pages in minutes instead of hours. The Figma-to-code flow is a game changer for my workflow.”
