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 1 July 2026; the live site may have changed since.

Invio is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on July 1, 2026. The site is hosted on IONOS, with a domain registered 2 days before launch. The crawl picked up 11 technologies on this site, covering hosting, analytics, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.

For context, it's one of 77 launches on this exact stack.
