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

Ace Calculator is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and incomplete email security.

Launched on Product Hunt on April 19, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 7 months before launch. The crawl picked up 24 technologies on this site, covering wordpress plugin, advertising, analytics, and business email. The stack includes Vite, WordPress, and Ahrefs.

For context, it's on a stack we've seen on only 22 launches.
