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 17 June 2026; the live site may have changed since.

PromptRender has the basics covered well, with a thorough launch checklist and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on June 17, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 3 months before launch. Our crawler found 13 technologies on this site, covering analytics, advertising, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.

Notably, it's on one of the most common stacks we track, shared by 7,861 launches.
