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 2 August 2026; the live site may have changed since.
SubnetLayer: Learn Protocols Visually scores highly overall, with a complete set of security headers, a thorough launch checklist, and well-configured email security. Visible gaps: incomplete legal pages.
Launched on Product Hunt on August 2, 2026. The site is served through Cloudflare, with a domain registered 4 days before launch. The crawl picked up 10 technologies on this site, covering business email, CDN, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.
For context, it's on one of the most common stacks we track, shared by 4,548 launches and more locked down than the typical Product Hunt launch.
