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.

LLMs.txt Generator & Validator ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. What needs work: analytics without a consent banner and incomplete email security.

Launched on Product Hunt on June 9, 2026. The site is hosted on Cloudflare in the United States. The crawl picked up 17 technologies on this site, covering analytics, CDN, baas, and captcha. The stack includes Nuxt, Tailwind CSS, and Vue.js.

For context, it's on a stack we've seen on only 3 launches and tighter on security headers than most Product Hunt launches.
