We just launched Visdiff and we're live on the leaderboard today.
One thing we kept running into at our dev agency: AI coding tools generate frontends fast, but the output never matches the design. Spacing is off, fonts don't match, colors are slightly wrong. You end up spending 3-5 hours per page fixing things that should've been right the first time.
Visdiff fixes that, paste your Figma link, it generates code, screenshots the result, compares it pixel-by-pixel to your design, and keeps iterating until it actually matches.
