Hey PH! 👋
I'm Danny, the maker of Knallhart.dev.
The idea came from years of building websites for clients and always having more honest opinions about their sites privately than I'd ever put in a formal audit.
So I built a tool that does exactly that — brutally honest, no fluff.
The hardest part wasn't the AI. It was getting Playwright to reliably screenshot modern websites with lazy loading and scroll animations. That took way longer than expected.
Happy to answer any questions about the product or the build. And yes — you can roast your own site. The irony is the point. 🔥
