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 April 2026; the live site may have changed since.
Cai has the basics covered well, with complete legal pages, a thorough launch checklist, and well-configured email security. What needs work: missing several security headers.
Launched on Hacker News on April 22, 2026. The site is hosted on GitHub Pages and served through Fastly, with a domain registered 11 weeks before launch. Our crawler found 13 technologies on this site, covering email marketing, security, analytics, and CDN. The stack includes Astro, Fastly, and GitHub Pages.
It's also one of 30 launches on this exact stack.
