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 18 July 2026; the live site may have changed since.

PrintBlocks is early-stage. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on July 17, 2026. The site is hosted on GitHub Pages and served through Fastly. We've detected 5 technologies on this site, covering CDN, frameworks, hosting, and javascript library. The stack includes Vue.js, Fastly, and GitHub Pages.

It's one of 32 launches on this exact stack.
