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

Modern Master Key is missing several launch fundamentals. Main gaps: missing several security headers, no robots.txt or sitemap, and incomplete email security.

Launched on Product Hunt on April 7, 2026. The site is hosted on Namecheap in the United States, with a domain registered 7 months before launch. Our crawler found 8 technologies on this site, covering business email, DNS providers, email marketing, and web fonts. The stack includes Google Fonts, Google Search Console, and LiteSpeed Web Server.
