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 20 April 2026; the live site may have changed since.

Pen Note has the basics covered well, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on PeerPush on April 20, 2026. The site is hosted on Hostinger and served through Cloudflare, with a domain registered 9 months before launch. Our crawler found 22 technologies on this site, covering analytics, hosting, security, and video. The stack includes Clerk, Next.js, and React.

It's also running the same core stack as 372 other launches.
