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.
Math Builders is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers, analytics without a consent banner, and incomplete email security.
Launched on Product Hunt on June 9, 2026. The site is hosted on Fastly in the United States, with a domain registered in 1998. The crawl picked up 10 technologies on this site, covering analytics, baas, build tooling, and CDN. The stack includes Vite, Contentsquare, and Fastly.
For context, it's running the same core stack as 710 other launches.
