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 13 April 2026; the live site may have changed since.
Sellup.io scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Visible gaps: incomplete email security.
Launched on Product Hunt on April 3, 2026. The site is hosted on The Constant Company in the United States. The crawl picked up 9 technologies on this site, covering CSS frameworks, DNS providers, transactional email, and web fonts. The stack includes Tailwind CSS, Google Fonts, and Google Search Console.
For context, it's on one of the most common stacks we track, shared by 5,951 launches and more locked down than the typical Product Hunt launch.
