Own this Launch?

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 16 April 2026; the live site may have changed since.

Sheet Hero is early-stage. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on April 16, 2026. The site is hosted on OVH in France, with a domain registered 2 weeks before launch. We've detected 6 technologies on this site, covering analytics, DNS providers, business email, and web fonts. The stack includes Google Analytics, Google Fonts, and nginx.
