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 June 2026; the live site may have changed since.

Sentibook ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: incomplete email security.

Launched on Hacker News on June 20, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 3 months before launch. We've detected 11 technologies on this site, covering CDN, CSS frameworks, DNS providers, and transactional email. The stack includes React, Tailwind CSS, and Adobe Fonts.

It's on a stack we've seen on only 7 launches and tighter on security headers than most Hacker News launches.
