Own this Launch?

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 22 April 2026; the live site may have changed since.

Librethinker is partway there, with a thorough launch checklist, fast page loads, and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and no email security records.

Launched on Hacker News on April 22, 2026. The site is served through Cloudflare, with a domain registered 4 months before launch. The crawl picked up 6 technologies on this site, covering CDN, CSS frameworks, DNS providers, and meta-frameworks. The stack includes Astro, Tailwind CSS, and Cloudflare.

For context, it's on one of the most common stacks we track, shared by 468 launches.
