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 9 June 2026; the live site may have changed since.

Sudoku Multiverse still has work before launch. Main gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on June 9, 2026. The site is hosted on Fastly in the United States, with a domain registered 7 weeks before launch. The crawl picked up 7 technologies on this site, covering advertising, CDN, consent tooling, and DNS providers. The stack includes Google Funding Choices, Fastly, and GitHub Pages.

For context, it's on one of the most common stacks we track, shared by 1,019 launches.
