Reviewer scorecard
“The team ships fast and responds to feedback. Good sign.”
“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.”
“This fills a real gap in the ecosystem. Worth adopting early.”
“Does one thing extremely well: turning ideas into working UI. It won't replace a designer, but it eliminates the blank canvas problem.”
“The code quality is surprisingly good — real shadcn components, not generic divs with inline styles. Saves me 2-3 hours per UI component.”
