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

HTMstudio is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers and incomplete email security.

Launched on Product Hunt on June 15, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 2 weeks before launch. The crawl picked up 6 technologies on this site, covering email marketing, frameworks, hosting, and meta-frameworks. The stack includes Next.js, React, and Brevo.

For context, it's on one of the most common stacks we track, shared by 1,494 launches.
