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 7 June 2026; the live site may have changed since.

RxDiff is largely in shape, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on June 7, 2026. The site is hosted on Google LLC in the United States, with a domain registered 11 months before launch. The crawl picked up 10 technologies on this site, covering AI builders, build tooling, CSS frameworks, and web fonts. The stack includes Express, Tailwind CSS, and Vite.

For context, it's on a stack we've seen on only 10 launches.
