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 July 2026; the live site may have changed since.

Altworld.io has the basics covered well, with complete legal pages, a thorough launch checklist, and fast page loads. What needs work: missing several security headers and incomplete email security.

Launched on Product Hunt on July 7, 2026. The site is hosted on Vercel. Our crawler found 14 technologies on this site, covering analytics, CSS frameworks, DNS providers, and business email. The stack includes Next.js, React, and Tailwind CSS.

It's also running the same core stack as 9,602 other launches.
