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 23 August 2026; the live site may have changed since.

Retrolien is partway there, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and no email security records.

Launched on Product Hunt on August 23, 2026. The site is hosted on Hetzner Online GmbH in Germany, with a domain registered 1 week before launch. The crawl picked up 6 technologies on this site, covering CSS frameworks, DNS providers, frameworks, and meta-frameworks. The stack includes Next.js, React, and Tailwind CSS.

For context, it's running the same core stack as 5,303 other launches.
