AI as Cognitive Gym Equipment
Booker is a book platform for the Foundations of Music project - a clean, media-rich conceptual book experience.
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 22 August 2026; the live site may have changed since.
AI as Cognitive Gym Equipment still has work before launch. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.
Launched on Hacker News on August 22, 2026. The site is hosted on Google Cloud, with a domain registered in 2021. The crawl picked up 9 technologies on this site, covering ui library, AI builders, backend framework, and CSS frameworks. The stack includes Tailwind CSS, Express, and Google Cloud.
For context, it's on one of the most common stacks we track, shared by 759 launches.
