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.
PDF Bill Builder scores well across the board, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing Permissions-Policy and Content-Security-Policy and no email security records.
Launched on Product Hunt on June 9, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 5 days before launch. Our crawler found 12 technologies on this site, covering advertising, analytics, auth, and consent tooling. The stack includes Google Funding Choices, Google Sign-In, and Next.js.
Notably, it's on one of the most common stacks we track, shared by 7,148 launches and more locked down than the typical Product Hunt launch.
