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 19 June 2026; the live site may have changed since.
PfdLabs — Professional Flowchart Builder scores well across the board, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing Permissions-Policy and Content-Security-Policy and incomplete email security.
Launched on Product Hunt on June 19, 2026. The site is hosted on Contabo GmbH in Germany, with a domain registered 8 months before launch. We've detected 8 technologies on this site, covering analytics, DNS providers, business email, and web fonts. The stack includes Google Analytics, Google Fonts, and Google Search Console.
It's more locked down than the typical Product Hunt launch.
