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 13 April 2026; the live site may have changed since.
Keplars has the basics covered well, with complete legal pages, a thorough launch checklist, and well-configured email security. Worth fixing first: missing several security headers.
Launched on Product Hunt on April 1, 2026. The site is served through Cloudflare, with a domain registered 11 weeks before launch. Our crawler found 9 technologies on this site, covering CDN, CSS frameworks, DNS providers, and business email. The stack includes Next.js, React, and Tailwind CSS.
It's also running the same core stack as 3,884 other launches.
