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 August 2026; the live site may have changed since.
The Regret Calculator is partway there, with complete legal pages and a thorough launch checklist. Worth fixing first: missing several security headers, no robots.txt or sitemap, and incomplete email security.
Launched on Product Hunt on August 17, 2026. The site is hosted on Vercel, with a domain registered 6 months before launch. The crawl picked up 13 technologies on this site, covering javascript library, baas, CSS frameworks, and developer tools. The stack includes Tailwind CSS, Firebase, and Google Fonts.
For context, it's running the same core stack as 2,973 other launches.
