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 7 July 2026; the live site may have changed since.

DerFit covers some of the launch checklist, with complete legal pages. Main gaps: missing several security headers, no robots.txt or sitemap, and incomplete email security.

Launched on PeerPush on July 7, 2026. The site is hosted on Netlify, with a domain registered in 2025. Our crawler found 7 technologies on this site, covering security, DNS providers, business email, and email marketing. The stack includes Brevo, Google Fonts, and Google reCAPTCHA.

It's also on one of the most common stacks we track, shared by 1,434 launches.
