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 19 April 2026; the live site may have changed since.

Sendox looks production-ready overall, with complete legal pages, well-configured email security, and clean crawl signals. Worth fixing first: missing several security headers and tracking cookies set before any opt-in.

Launched on Product Hunt on April 19, 2026. The site is hosted on Vercel. We've detected 11 technologies on this site, covering analytics, CSS frameworks, DNS providers, and email forwarding. The stack includes Next.js, React, and Tailwind CSS.

It's running the same core stack as 10,671 other launches.
