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.
Free PDF Unlock ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: tracking cookies set before any opt-in and incomplete email security.
Launched on Product Hunt on June 17, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 1 day before launch. We've detected 9 technologies on this site, covering analytics, CDN, CSS frameworks, and DNS providers. The stack includes Tailwind CSS, Cloudflare, and Cloudflare DNS.
It's running the same core stack as 1,126 other launches and tighter on security headers than most Product Hunt launches.
