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

Duplipost scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers and incomplete email security.

Launched on Product Hunt on June 30, 2026. The site is hosted on Vercel, with a domain registered 11 months before launch. Our crawler found 10 technologies on this site, covering transactional email, CSS frameworks, DNS providers, and email forwarding. The stack includes Next.js, React, and Tailwind CSS.

It's also on one of the most common stacks we track, shared by 8,976 launches.
