StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 23 June 2026; the live site may have changed since.
Knob has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers, tracking cookies set before any opt-in, and no email security records.
Launched on Hacker News on June 23, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 3 weeks before launch. Our crawler found 9 technologies on this site, covering web fonts, analytics, CSS frameworks, and DNS providers. The stack includes Tailwind CSS, Fontshare, and Google Fonts.
Notably, it's on one of the most common stacks we track, shared by 2,023 launches.
