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

MathMarmot ships with the basics, with a thorough launch checklist, fast page loads, and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on August 18, 2026. The site is hosted on Fly.io, with a domain registered 4 days before launch. We've detected 5 technologies on this site, covering DNS providers, business email, email forwarding, and hosting. The stack includes Fly.io, Google Search Console, and Namecheap DNS.

It's on one of the most common stacks we track, shared by 114 launches.
