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

Customs Validator is partway there, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on June 24, 2026. The site is hosted on Namecheap in the United States, with a domain registered 5 weeks before launch. The crawl picked up 12 technologies on this site, covering transactional email, advertising, analytics, and baas. The stack includes Amazon SES, Google Ads, and Google Analytics.

For context, it's running the same core stack as 389 other launches.
