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 18 April 2026; the live site may have changed since.
Free Email Signature Builder scores highly overall, with complete legal pages, a thorough launch checklist, and fast page loads. Main gaps: missing Permissions-Policy and Content-Security-Policy and incomplete email security.
Launched on Hacker News on April 18, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 3 months before launch. Our crawler found 17 technologies on this site, covering analytics, CDN, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.
It's also on one of the most common stacks we track, shared by 10,662 launches and more locked down than the typical Hacker News launch.
