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

Plumerie: Home Library App has the basics covered well, with complete legal pages, a thorough launch checklist, and fast page loads. Visible gaps: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on June 11, 2026. The site is hosted on Vercel, with a domain registered 4 months before launch. Our crawler found 11 technologies on this site, covering analytics, transactional email, CSS frameworks, and DNS providers. The stack includes React, Tailwind CSS, and Glyphex.

It's also one of 54 launches on this exact stack.
