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 26 April 2026; the live site may have changed since.
Calcverse.tools is largely in shape, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and incomplete email security.
Launched on Product Hunt on April 26, 2026. The site is hosted on Google Cloud, with a domain registered 3 days before launch. The crawl picked up 19 technologies on this site, covering advertising, consent tooling, hosting, and AI builders. The stack includes Gatekeeper, Google Funding Choices, and Tailwind CSS.
For context, it's on a stack we've seen on only 4 launches.
