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.
Calcosy scores highly overall, with a complete set of security headers, a thorough launch checklist, and fast page loads. Main gaps: incomplete legal pages and incomplete email security.
Launched on Product Hunt on April 16, 2026. The site is hosted on Vercel, with a domain registered 1 week before launch. The crawl picked up 11 technologies on this site, covering advertising, analytics, data api, and developer tools. The stack includes Cloudflare DNS, Cloudflare Email Routing, and Frankfurter.
For context, it's on one of the most common stacks we track, shared by 2,956 launches and more locked down than the typical Product Hunt launch.
