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 17 August 2026; the live site may have changed since.
LengPrep has the basics covered well, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing Content-Security-Policy and Strict-Transport-Security, incomplete legal pages, and no email security records.
Launched on Product Hunt on August 17, 2026. The site is served through Cloudflare, with a domain registered 8 weeks before launch. Our crawler found 11 technologies on this site, covering analytics, ai api, baas, and CDN. The stack includes Anthropic, Cloudflare, and Cloudflare Bot Management.
It's also tighter on security headers than most Product Hunt launches.
