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

Live PDF Preview is partway there, with complete legal pages, a thorough launch checklist, and well-configured email security. Main gaps: missing several security headers and no robots.txt or sitemap.

Launched on Product Hunt on July 1, 2026. The site is served through Cloudflare. The crawl picked up 7 technologies on this site, covering CDN, CSS frameworks, frameworks, and javascript library. The stack includes Next.js, React, and Tailwind CSS.

For context, it's on one of the most common stacks we track, shared by 3,205 launches.
