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 27 June 2026; the live site may have changed since.
Calcento is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and incomplete email security.
Launched on Product Hunt on June 27, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 1 week before launch. The crawl picked up 11 technologies on this site, covering advertising, analytics, consent tooling, and CSS frameworks. The stack includes Google Funding Choices, Next.js, and React.
For context, it's running the same core stack as 8,685 other launches.

Readiness Breakdown How?
Performance How?
Indicative grade from a single automated render, not a substitute for Lighthouse or field data, and not part of the StackScope score.
Vibe Score Breakdown How?
| Signal | Points |
|---|---|
| AI writing signals | +5 |
| AI iconography signals | +5 |
This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
