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 10 April 2026; the live site may have changed since.
InboxSure ships with the basics, with complete legal pages and well-configured email security. What needs work: missing several security headers and no robots.txt or sitemap.
Launched on Product Hunt on April 8, 2026. The site is hosted on Vercel. We've detected 10 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 10,661 other launches.
