Vprinter

Virtual Printer for your ESC/POS prints

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 7 June 2026; the live site may have changed since.

Vprinter is partway there, with complete legal pages and a thorough launch checklist. Visible gaps: missing several security headers, no sitemap, and incomplete email security.

Launched on Hacker News on June 7, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 6 weeks before launch. The crawl picked up 10 technologies on this site, covering CDN, CSS frameworks, DNS providers, and business email. The stack includes Next.js, React, and Tailwind CSS.

For context, it's on one of the most common stacks we track, shared by 457 launches.
