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 June 2026; the live site may have changed since.

Swiftbill is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers and no email security records.

Launched on Product Hunt on June 14, 2026. The site is hosted on Amazon.com in the United States, with a domain registered the day of launch. The crawl picked up 7 technologies on this site, covering CSS frameworks, DNS providers, transactional email, and frameworks. The stack includes Next.js, React, and Tailwind CSS.

For context, it's running the same core stack as 7,434 other launches.
