Own this Launch?

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

WriteSpark covers some of the launch checklist, with complete legal pages and a thorough launch checklist. Main gaps: missing several security headers, no robots.txt or sitemap, and no email security records.

Launched on Product Hunt on June 6, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 3 days before launch. Our crawler found 6 technologies on this site, covering CSS frameworks, DNS providers, frameworks, and hosting. The stack includes Next.js, React, and Tailwind CSS.

Notably, it's on one of the most common stacks we track, shared by 6,734 launches.
