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

Dosti Labs - Learn languages by speaking is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and no email security records.

Launched on Product Hunt on July 12, 2026. The site is hosted on Vercel, with a domain registered 1 week before launch. The crawl picked up 4 technologies on this site, covering DNS providers, web fonts, hosting, and security. The stack includes Google Fonts, HSTS, and Vercel.

For context, it's running the same core stack as 2,766 other launches.
