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 August 2026; the live site may have changed since.
Combina tus archivos PDF en uno gratis — Unir PDF Online looks production-ready overall, 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.
The site is served through Cloudflare, with a domain registered 3 days before launch. We've detected 12 technologies on this site, covering javascript library, package cdn, analytics, and CDN. The stack includes Svelte, cdnjs, and Cloudflare.
It's one of 73 launches on this exact stack.
