Screenshot of CarrySizer

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

CarrySizer ships with the launch fundamentals in place, with a complete set of security headers, a thorough launch checklist, and clean crawl signals. What needs work: incomplete legal pages and no email security records.

Launched on Product Hunt on June 27, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 1 week before launch. The crawl picked up 12 technologies on this site, covering analytics, seo, advertising, and CSS frameworks. The stack includes Next.js, React, and Tailwind CSS.

For context, it's running the same core stack as 8,685 other launches and tighter on security headers than most Product Hunt launches.
