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 24 August 2026; the live site may have changed since.
Working Days Calculator is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers and incomplete email security.
Launched on Product Hunt on August 24, 2026. The site is hosted on Vercel, with a domain registered 1 week before launch. The crawl picked up 9 technologies on this site, covering CSS frameworks, DNS providers, web fonts, and frameworks. The stack includes Alpine.js, Tailwind CSS, and GoDaddy DNS.
For context, it's one of just 10 launches we've crawled on this exact stack.
