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 15 April 2026; the live site may have changed since.
StampPDF is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on April 13, 2026. The site is hosted on DigitalOcean in the United States, with a domain registered 8 months before launch. The crawl picked up 15 technologies on this site, covering wordpress plugin, business email, analytics, and CMS. The stack includes WordPress, Cloudflare DNS, and Elementor.
For context, it's on one of the most common stacks we track, shared by 1,186 launches.
