Reviewer scorecard
“Best instruction-following of any model. Tool use and extended thinking are reliable. The API design is clean.”
“The code quality is surprisingly good — real shadcn components, not generic divs with inline styles. Saves me 2-3 hours per UI component.”
“Claude consistently produces the most useful outputs for real work. The longer context window is a genuine advantage.”
“Does one thing extremely well: turning ideas into working UI. It won't replace a designer, but it eliminates the blank canvas problem.”
“Anthropic's focus on safety without sacrificing capability is the right approach. Claude keeps getting better.”
“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.”
