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 20 July 2026; the live site may have changed since.
Mailthentic ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: no Permissions-Policy and incomplete email security.
Launched on Product Hunt on July 20, 2026. The site is hosted on Hostinger, with a domain registered 4 months before launch. The crawl picked up 20 technologies on this site, covering advertising, analytics, captcha, and CSS frameworks. The stack includes Tailwind CSS, Bing Ads, and Cloudflare Turnstile.
For context, it's running the same core stack as 576 other launches and tighter on security headers than most Product Hunt launches.
