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 3 July 2026; the live site may have changed since.

Mirrors is largely in shape, with a complete set of security headers, a thorough launch checklist, and clean crawl signals. What needs work: incomplete legal pages, tracking cookies set before any opt-in, and incomplete email security.

Launched on Hacker News on July 2, 2026. The site is hosted on Vercel, with a domain registered 1 week before launch. The crawl picked up 12 technologies on this site, covering analytics, baas, developer tools, and DNS providers. The stack includes Google Fonts, Google Search Console, and HSTS.

For context, it's running the same core stack as 2,481 other launches and tighter on security headers than most Hacker News launches.
