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 July 2026; the live site may have changed since.
Mastering.to scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Main gaps: incomplete email security.
Launched on Product Hunt on July 16, 2026. The site is hosted on Vercel, with a domain registered in 2022. We've detected 13 technologies on this site, covering analytics, developer tools, DNS providers, and business email. The stack includes Google Analytics, Google Fonts, and Google Search.
It's on one of the most common stacks we track, shared by 2,903 launches and more locked down than the typical Product Hunt launch.
