Own this Launch?

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

PDF Toolkit is missing several launch fundamentals. What needs work: missing several security headers, incomplete legal pages, and no robots.txt.

Launched on Product Hunt on July 27, 2026. The site is hosted on Google LLC in the United States, with a domain registered in 2023. Our crawler found 8 technologies on this site, covering javascript library, analytics, CSS frameworks, and developer tools. The stack includes Tailwind CSS, Google Analytics, and Google Tag Manager.

It's also running the same core stack as 6,367 other launches.
