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 19 April 2026; the live site may have changed since.
CardStack is partway there, with complete legal pages and a thorough launch checklist. What needs work: missing several security headers, no sitemap, and tracking cookies set before any opt-in.
Launched on Product Hunt on April 19, 2026. The site is hosted on Railway and served through Cloudflare, with a domain registered 8 weeks before launch. The crawl picked up 10 technologies on this site, covering analytics, CDN, CSS frameworks, and DNS providers. The stack includes Tailwind CSS, Cloudflare, and Cloudflare DNS.
For context, it's running the same core stack as 269 other launches.
