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 4 June 2026; the live site may have changed since.
Merge PDF Files Online scores well across the board, with a thorough launch checklist and clean crawl signals. Main gaps: no Permissions-Policy, incomplete legal pages, and incomplete email security.
Launched on Product Hunt on June 4, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 3 months before launch. The crawl picked up 20 technologies on this site, covering analytics, advertising, social embeds, and CDN. The stack includes Google Funding Choices, Tailwind CSS, and Buy Me a Coffee.
For context, it's on one of the most common stacks we track, shared by 961 launches and more locked down than the typical Product Hunt launch.
