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 10 June 2026; the live site may have changed since.
LayerProof Vellum is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers, analytics without a consent banner, and incomplete email security.
Launched on Product Hunt on June 10, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 4 months before launch. The crawl picked up 17 technologies on this site, covering advertising, analytics, CDN, and chat widgets. The stack includes Astro, Tailwind CSS, and Amazon SES.
For context, it's on a stack we've seen on only 20 launches.
