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 8 July 2026; the live site may have changed since.
Sieve has the basics covered well, with complete legal pages, a complete set of security headers, and well-configured email security. What needs work: no robots.txt or sitemap and tracking cookies set before any opt-in.
Launched on Product Hunt on July 8, 2026. The site is hosted on Vercel. Our crawler found 10 technologies on this site, covering analytics, DNS providers, business email, and transactional email. The stack includes Next.js, React, and Google Search Console.
It's also running the same core stack as 2,083 other launches and tighter on security headers than most Product Hunt launches.
