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

WinSend covers some of the launch checklist, with fast page loads and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on April 16, 2026. The site is served through Cloudflare, with a domain registered 2 weeks before launch. Our crawler found 9 technologies on this site, covering analytics, CDN, CSS frameworks, and DNS providers. The stack includes Tailwind CSS, Cloudflare, and Cloudflare DNS.

It's also on one of the most common stacks we track, shared by 5,951 launches.
