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 11 April 2026; the live site may have changed since.
Calcul Mental Challenge par Studiophel has the basics covered well, with a thorough launch checklist, well-configured email security, and fast page loads. Visible gaps: missing Permissions-Policy and Content-Security-Policy and incomplete legal pages.
Launched on Product Hunt on April 10, 2026. The site is hosted on IONOS, with a domain registered in 2024. Our crawler found 7 technologies on this site, covering DNS providers, business email, web fonts, and hosting. The stack includes Google Fonts, Google Search Console, and HSTS.
It's also on one of the most common stacks we track, shared by 127 launches and more locked down than the typical Product Hunt launch.
