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 11 August 2026; the live site may have changed since.

Sponsor Seal looks production-ready overall, with complete legal pages and clean crawl signals. Visible gaps: missing several security headers, tracking cookies set before any opt-in, and no email security records.

Launched on Product Hunt on August 11, 2026. The site is hosted on Vercel, with a domain registered 3 months before launch. We've detected 13 technologies on this site, covering analytics, ui library, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.

It's on one of the most common stacks we track, shared by 12,865 launches.
