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 27 April 2026; the live site may have changed since.
Replyless - Best Superhuman Alternative ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. What needs work: tracking cookies set before any opt-in and incomplete email security.
Launched on Product Hunt on April 27, 2026. The site is hosted on Hostinger and served through Cloudflare, with a domain registered 3 months before launch. Our crawler found 21 technologies on this site, covering security, analytics, email marketing, and hosting. The stack includes Tailwind CSS, Brevo, and Cloudflare.
It's also one of 93 launches on this exact stack and tighter on security headers than most Product Hunt launches.
