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

Withcorpus covers some of the launch checklist, with complete legal pages, well-configured email security, and fast page loads. Visible gaps: missing several security headers and no robots.txt or sitemap.

Launched on Hacker News on August 24, 2026. The site is hosted on Vercel, with a domain registered 6 days before launch. Our crawler found 7 technologies on this site, covering CSS frameworks, DNS providers, transactional email, 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 13,908 launches.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
