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

InvoiceWatchr 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.
