What it does
Flawless uses GPT-4-Vision to audit your landing page for design and usability issues, offering actionable fixes to improve your user experience and conversion rates
Flawless audits your website and pinpoints usability, messaging, SEO, and functionality issues right on your pages, with AI fix prompts you can copy into Cursor, Claude Code, or Lovable.
Paste any URL. We automatically discover critical pages like homepage, pricing, and signup. Choose which pages to include in your audit. Each page is captured on desktop and mobile, then analyzed for layout, messaging, trust signals, SEO, and more. Every issue is pinned to the exact spot on your page. Every fix includes what to change, why it matters, and how to verify it. Share the audit with your team or contractor, or copy fix prompts directly into Cursor, Claude Code, or Lovable. Most tools run a fixed checklist on each page in isolation. Flawless reasons across your whole site, catching inconsistent messaging, broken flows, and gaps that only show up when you look at the full picture.…from flawless.is

Last week, I launched it on Hacker News…

SpeedVitals▲829Hi HN, I’m Kashish, one of the co-founders of SpeedVitals, a platform for testing & monitoring website performance with a major emphasis on Core Web Vitals. Until now, our platform has only focused on Synthetic/Lab testing, such as Lighthouse tests and TTFB tests. But now, we have developed a Real-User Monitoring platform that doubles up as a Web Analytics tool. One major feature we have that most RUM tools lack is Performance Audits. Just like Lighthouse audits work on Lab test data, our audits work across all the real-user visits and gives suggestions on what task to prioritize first.…
