Own this Launch?

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 17 June 2026; the live site may have changed since.

WebDevCalc looks production-ready overall, with clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on June 17, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 3 weeks before launch. We've detected 9 technologies on this site, covering advertising, analytics, consent tooling, and DNS providers. The stack includes Google Funding Choices, GoatCounter, and Google Ads.

It's on one of the most common stacks we track, shared by 1,015 launches.
