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 12 August 2026; the live site may have changed since.
Lettertrace is largely in shape, with complete legal pages, a thorough launch checklist, and fast page loads. What needs work: missing several security headers, no robots.txt or sitemap, and no email security records.
Launched on Product Hunt on August 12, 2026. The site is hosted on Vercel, with a domain registered in 2025. The crawl picked up 7 technologies on this site, covering CSS frameworks, DNS providers, frameworks, and hosting. The stack includes Next.js, React, and Tailwind CSS.
For context, it's running the same core stack as 12,967 other launches.
