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 28 April 2026; the live site may have changed since.
CalcLane has the basics covered well, with complete legal pages and clean crawl signals. What needs work: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on April 28, 2026. The site is hosted on Plesk, with a domain registered 5 days before launch. Our crawler found 6 technologies on this site, covering analytics, DNS providers, web fonts, and hosting. The stack includes GoDaddy DNS, Google Analytics, and Google Fonts.
It's also one of 76 launches on this exact stack.
