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

TabMail ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and well-configured email security. Worth fixing first: missing several security headers.

Launched on Product Hunt on April 22, 2026. The site is served through Cloudflare, with a domain registered 6 months before launch. The crawl picked up 10 technologies on this site, covering baas, CDN, DNS providers, and business email. The stack includes Cloudflare, Cloudflare DNS, and Google Search Console.
