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 29 July 2026; the live site may have changed since.

MRXSIM scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Main gaps: no sitemap and no email security records.

Launched on Product Hunt on July 29, 2026. The site is served through Cloudflare, with a domain registered 5 days before launch. We've detected 17 technologies on this site, covering APIs, auth, analytics, and captcha. The stack includes Google OAuth, Google Sign-In, and Tailwind CSS.

It's on one of the most common stacks we track, shared by 6,397 launches and more locked down than the typical Product Hunt launch.
