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 July 2026; the live site may have changed since.

WalletU ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and fast page loads. What needs work: no Content-Security-Policy and no email security records.

Launched on Product Hunt on July 23, 2026. The site is served through Cloudflare, with a domain registered 1 day before launch. The crawl picked up 9 technologies on this site, covering analytics, CDN, CSS frameworks, and DNS providers. The stack includes Astro, Tailwind CSS, and Cloudflare.

For context, it's running the same core stack as 510 other launches and tighter on security headers than most Product Hunt launches.
