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

Prompt Builder ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and well-configured email security. What needs work: no X-Frame-Options and tracking cookies set before any opt-in.

Launched on Hacker News on August 26, 2026. The site is hosted on Vercel. Our crawler found 24 technologies on this site, covering analytics, advertising, transactional email, and seo. The stack includes Next.js, React, and Tailwind CSS.

It's also running the same core stack as 14,158 other launches and tighter on security headers than most Hacker News launches.
