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 25 June 2026; the live site may have changed since.

Mass Email PRO covers some of the launch checklist, with complete legal pages. Worth fixing first: missing several security headers, no robots.txt or sitemap, and no email security records.

Launched on Product Hunt on June 25, 2026. The site is hosted on Amazon.com in the United States. Our crawler found 6 technologies on this site, covering developer tools, web fonts, hosting, and javascript library. The stack includes Choices.js, Google Fonts, and HSTS.

Notably, it's running the same core stack as 2,294 other launches.
