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 27 August 2026; the live site may have changed since.

Endurance Softwares looks production-ready overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Worth fixing first: missing several security headers and tracking cookies set before any opt-in.

Launched on Product Hunt on August 27, 2026. The site is hosted on Vercel, with a domain registered in 2018. We've detected 20 technologies on this site, covering directory, wordpress plugin, analytics, and CMS. The stack includes Next.js, React, and WordPress.

It's running a stack combination we've seen on no other launch.
