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

PDF Toolkit still has work before launch. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on July 7, 2026. The site is hosted on Netlify. The crawl picked up 8 technologies on this site, covering javascript library, web fonts, hosting, and package cdn. The stack includes cdnjs, Google Fonts, and Google Search Console.

For context, it's running the same core stack as 1,433 other launches.
