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

Lennyfighter is missing several launch fundamentals. Worth fixing first: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Hacker News on April 21, 2026. The site is served through Cloudflare, with a domain registered 4 weeks before launch. Our crawler found 5 technologies on this site, covering CDN, developer tools, DNS providers, and web fonts. The stack includes Cloudflare, Cloudflare DNS, and Google Fonts.
