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.

dTax ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist.

Launched on Product Hunt on April 16, 2026. The site is hosted on Oracle Corporation in the United States, with a domain registered 5 weeks before launch. We've detected 14 technologies on this site, covering analytics, seo, DNS providers, and email forwarding. The stack includes Next.js, React, and Baidu Webmaster Tools.

It's running the same core stack as 762 other launches and tighter on security headers than most Product Hunt launches.
