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 28 April 2026; the live site may have changed since.

FastAiZip is largely in shape, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and no email security records.

Launched on Product Hunt on April 28, 2026. The site is hosted on Alibaba US Technology Co. in the United States, with a domain registered 1 week before launch. The crawl picked up 7 technologies on this site, covering CSS frameworks, DNS providers, frameworks, and meta-frameworks. The stack includes Next.js, React, and Tailwind CSS.

For context, it's on one of the most common stacks we track, shared by 3,880 launches.
