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

Free Pdf Edit, Sign & Redact Offline is partway there, with a thorough launch checklist, well-configured email security, and clean crawl signals. What needs work: missing several security headers and incomplete legal pages.

Launched on Product Hunt on August 20, 2026. The site is served through Fastly, with a domain registered 4 months before launch. The crawl picked up 5 technologies on this site, covering CDN, developer tools, javascript library, and security. The stack includes Fastly, HSTS, and Lucide Icons.
