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 30 June 2026; the live site may have changed since.

PDF SignCheck ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: tracking cookies set before any opt-in and incomplete email security.

Launched on PeerPush on June 30, 2026. The site is hosted on Hostinger, with a domain registered 4 weeks before launch. Our crawler found 19 technologies on this site, covering advertising, analytics, hosting, and javascript library. The stack includes Next.js, React, and Bing Ads.

It's also one of 45 launches on this exact stack and tighter on security headers than most PeerPush launches.
