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 30 April 2026; the live site may have changed since.

ElecCalc has the basics covered well, with a thorough launch checklist, well-configured email security, and clean crawl signals. Main gaps: missing several security headers and incomplete legal pages.

Launched on Product Hunt on April 30, 2026. The site is hosted on Vercel. Our crawler found 13 technologies on this site, covering advertising, analytics, consent tooling, and CSS frameworks. The stack includes Google Funding Choices, Next.js, and React.

It's also on one of the most common stacks we track, shared by 10,672 launches.
