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 17 June 2026; the live site may have changed since.
knallhart.dev - Brutally honest feedback covers some of the launch checklist, with complete legal pages and fast page loads. Worth fixing first: missing several security headers, no robots.txt or sitemap, and incomplete email security.
Launched on Product Hunt on June 17, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 3 weeks before launch. Our crawler found 6 technologies on this site, covering DNS providers, transactional email, frameworks, and hosting. The stack includes Next.js, React, and HSTS.
Notably, it's running the same core stack as 1,569 other launches.
