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 22 April 2026; the live site may have changed since.

Aperturasdeajedrez is partway there, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Hacker News on April 22, 2026. The site is hosted on Netlify, with a domain registered 5 weeks before launch. The crawl picked up 10 technologies on this site, covering advertising, analytics, CSS frameworks, and developer tools. The stack includes Tailwind CSS, Google Ads, and Google Analytics.

For context, it's running the same core stack as 640 other launches.
