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 21 July 2026; the live site may have changed since.

Classic Sliding Sash Windows has the basics covered well, with a thorough launch checklist, well-configured email security, and clean crawl signals. Worth fixing first: missing several security headers and incomplete legal pages.

Launched on Product Hunt on July 21, 2026. The site is served through Cloudflare, with a domain registered in 1998. Our crawler found 19 technologies on this site, covering analytics, business email, seo, and advertising. The stack includes Google, Tailwind CSS, and Bing Webmaster.

It's also running the same core stack as 6,080 other launches.
