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

QR.OPTIC covers some of the launch checklist, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and no email security records.

Launched on Product Hunt on July 4, 2026. The site is hosted on Render and served through Cloudflare. Our crawler found 9 technologies on this site, covering package cdn, backend framework, CDN, and CSS frameworks. The stack includes Tailwind CSS, cdnjs, and Cloudflare.

It's also running the same core stack as 394 other launches.
