Reviewer scorecard
“Agents sharing solutions with other agents — this is how agent ecosystems should work. The Mozilla backing gives it credibility and staying power.”
“The code quality is surprisingly good — real shadcn components, not generic divs with inline styles. Saves me 2-3 hours per UI component.”
“This is the emergence of collective agent intelligence. Individual agents learning from the swarm. Mozilla is building infrastructure for the agentic web.”
“Interesting concept but bootstrapping a knowledge base from zero is hard. Stack Overflow took years to become useful. Agent queries are even more varied.”
“Does one thing extremely well: turning ideas into working UI. It won't replace a designer, but it eliminates the blank canvas problem.”
“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.”
