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

Promptr is partway there, with complete legal pages. What needs work: missing several security headers, no robots.txt or sitemap, and no email security records.

Launched on Product Hunt on July 2, 2026. The site is hosted on Vercel. The crawl picked up 9 technologies on this site, covering analytics, CSS frameworks, DNS providers, and business email. The stack includes Next.js, React, and Tailwind CSS.

For context, it's running the same core stack as 9,146 other launches.
