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

OfferUnlock covers some of the launch checklist, with complete legal pages, a thorough launch checklist, and fast page loads. Main gaps: missing several security headers, no robots.txt or sitemap, and incomplete email security.

Launched on Hacker News on June 9, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 5 weeks before launch. Our crawler found 8 technologies on this site, covering CSS frameworks, DNS providers, business email, and transactional email. The stack includes Next.js, React, and Tailwind CSS.

Notably, it's on one of the most common stacks we track, shared by 7,148 launches.
