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.

PCalen has the basics covered well, with complete legal pages, a thorough launch checklist, and well-configured email security. What needs work: missing several security headers and tracking cookies set before any opt-in.

Launched on Product Hunt on June 17, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 7 weeks before launch. Our crawler found 16 technologies on this site, covering analytics, advertising, CDN, and CSS frameworks. The stack includes Nuxt, Tailwind CSS, and Vue.js.

Notably, it's running the same core stack as 132 other launches.
