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 4 June 2026; the live site may have changed since.

Sailbit has the basics covered well, with complete legal pages and a thorough launch checklist. Worth fixing first: missing Permissions-Policy and Content-Security-Policy, no robots.txt or sitemap, and analytics without a consent banner.

Launched on Product Hunt on June 4, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 4 weeks before launch. Our crawler found 8 technologies on this site, covering analytics, CSS frameworks, DNS providers, and transactional email. The stack includes Next.js, React, and Tailwind CSS.

Notably, it's running the same core stack as 6,602 other launches and tighter on security headers than most Product Hunt launches.
