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.

CardPeek covers some of the launch checklist, with complete legal pages. Visible gaps: missing several security headers, no robots.txt or sitemap, and incomplete email security.

Launched on Product Hunt on April 13, 2026. The site is hosted on Vercel, with a domain registered 1 day before launch. Our crawler found 10 technologies on this site, covering CSS frameworks, DNS providers, email forwarding, and transactional email. The stack includes Next.js, React, and Tailwind CSS.

It's also on one of the most common stacks we track, shared by 10,672 launches.
