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 10 June 2026; the live site may have changed since.
Librost looks production-ready overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Worth fixing first: missing several security headers, no sitemap, and analytics without a consent banner.
Launched on PeerPush on June 10, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 5 months before launch. We've detected 12 technologies on this site, covering CDN, advertising, analytics, and cloud. The stack includes Astro, Amazon Web Services, and AWS CloudFront.
It's on a stack we've seen on only 8 launches.
