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.

Silent Shark ships with the basics, with a thorough launch checklist. Main gaps: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Hacker News on August 12, 2026. The site is served through Cloudflare, with a domain registered 4 months before launch.
