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

Binary Decimal - Markdown Editor is largely in shape, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing Permissions-Policy and Content-Security-Policy, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on June 18, 2026. The site is hosted on Amazon.com in the United States, with a domain registered in 2016. The crawl picked up 7 technologies on this site, covering analytics, build tooling, CSS frameworks, and DNS providers. The stack includes Tailwind CSS, Vite, and Google Analytics.

For context, it's running the same core stack as 374 other launches and tighter on security headers than most Product Hunt launches.
