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 2 July 2026; the live site may have changed since.
EnglishJan scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Main gaps: no email security records.
Launched on Product Hunt on July 2, 2026. The site is hosted on Vercel. The crawl picked up 12 technologies on this site, covering analytics, baas, developer tools, and web fonts. The stack includes Firebase, Google Analytics, and Google Fonts.
For context, it's on one of the most common stacks we track, shared by 2,482 launches and more locked down than the typical Product Hunt launch.
