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

Letras Diferentes ships with the launch fundamentals in place, with a thorough launch checklist, well-configured email security, and clean crawl signals. Worth fixing first: no Content-Security-Policy and incomplete legal pages.

Launched on Product Hunt on June 9, 2026. The site is hosted on Cloudflare in the United States, with a domain registered in 2025. We've detected 14 technologies on this site, covering CDN, cloud, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.

It's running the same core stack as 2,430 other launches and tighter on security headers than most Product Hunt launches.
