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 2 August 2026; the live site may have changed since.

Marnetto still has work before launch. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on August 2, 2026. The site is served through Cloudflare, with a domain registered in 2024. The crawl picked up 7 technologies on this site, covering APIs, CDN, comments, and DNS providers. The stack includes Cloudflare, Cloudflare DNS, and Giscus.
