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 14 August 2026; the live site may have changed since.

401kmonitor has the basics covered well, with a complete set of security headers, a thorough launch checklist, and clean crawl signals. Main gaps: incomplete legal pages and incomplete email security.

Launched on Hacker News on August 14, 2026. The site is hosted on Vercel, with a domain registered 6 days before launch. Our crawler found 8 technologies on this site, covering CSS frameworks, DNS providers, email forwarding, and frameworks. The stack includes Next.js, React, and Tailwind CSS.

It's also on one of the most common stacks we track, shared by 13,132 launches and more locked down than the typical Hacker News launch.
