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 28 April 2026; the live site may have changed since.

NoSheetKit ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and well-configured email security. What needs work: missing several security headers.

Launched on Hacker News on April 27, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 3 weeks before launch. Our crawler found 9 technologies on this site, covering CDN, CSS frameworks, DNS providers, and frameworks. The stack includes Next.js, React, and Tailwind CSS.

It's also running the same core stack as 10,671 other launches.
