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

UPDF 2.5 looks production-ready overall, with complete legal pages, a thorough launch checklist, and fast page loads. Worth fixing first: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on April 3, 2026. The site is served through Cloudflare, with a domain registered in 2004. We've detected 23 technologies on this site, covering affiliate, analytics, advertising, and ai service. The stack includes Google Sign-In, Vue.js, and Alibaba Cloud.

It's running the same core stack as 249 other launches.
