Own this Launch?

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

HeimWall scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Main gaps: no email security records.

Launched on Hacker News on July 16, 2026. The site is hosted on Vercel, with a domain registered 3 months before launch. Our crawler found 12 technologies on this site, covering analytics, CSS frameworks, DNS providers, and business email. The stack includes Next.js, React, and Tailwind CSS.

It's also on one of the most common stacks we track, shared by 10,492 launches and more locked down than the typical Hacker News launch.
