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 10 April 2026; the live site may have changed since.

Sketchbook UI is missing several launch fundamentals. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on April 7, 2026. The site is hosted on GitHub Pages and served through Fastly. Our crawler found 6 technologies on this site, covering CDN, CSS frameworks, developer tools, and web fonts. The stack includes Tailwind CSS, Fastly, and GitHub Pages.

It's also running the same core stack as 207 other launches.
