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 15 August 2026; the live site may have changed since.
Invoice to PDF scores highly overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Visible gaps: missing Permissions-Policy and Strict-Transport-Security and tracking cookies set before any opt-in.
Launched on Product Hunt on August 15, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 5 days before launch. We've detected 6 technologies on this site, covering analytics, backend framework, CSS frameworks, and DNS providers. The stack includes Tailwind CSS, AWS Route 53, and Google Analytics.
It's on one of the most common stacks we track, shared by 6,999 launches and more locked down than the typical Product Hunt launch.
