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 25 June 2026; the live site may have changed since.
x401 covers some of the launch checklist. What needs work: missing several security headers, incomplete legal pages, and no sitemap.
Launched on Product Hunt on June 25, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 10 weeks before launch. Our crawler found 9 technologies on this site, covering analytics, CDN, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.
Notably, it's running the same core stack as 552 other launches.
