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

List Bulb is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on PeerPush on June 23, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 9 weeks before launch. The crawl picked up 55 technologies on this site, covering directory, hosting, security, and analytics. The stack includes Next.js, React, and Tailwind CSS.

For context, it's on one of the most common stacks we track, shared by 275 launches.
