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 16 April 2026; the live site may have changed since.
Callana has the basics covered well, with complete legal pages, a thorough launch checklist, and fast page loads. What needs work: missing several security headers and incomplete email security.
Launched on Product Hunt on April 16, 2026. The site is served through Cloudflare, with a domain registered 9 months before launch. Our crawler found 6 technologies on this site, covering CDN, CSS frameworks, DNS providers, and email forwarding. The stack includes Astro, Tailwind CSS, and Cloudflare.
It's also running the same core stack as 468 other launches.
