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 14 July 2026; the live site may have changed since.

Viaduct Chrome Extensions in Safari covers some of the launch checklist, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on July 14, 2026. The site is hosted on GitHub Pages and served through Fastly, with a domain registered 1 week before launch. Our crawler found 11 technologies on this site, covering web fonts, javascript library, CDN, and CSS frameworks. The stack includes Tailwind CSS, Cloudflare DNS, and Cloudflare Email Routing.

It's also running the same core stack as 202 other launches.
