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 August 2026; the live site may have changed since.
Real Sleep Calculator has the basics covered well, with complete legal pages, a thorough launch checklist, and fast page loads. Main gaps: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on August 27, 2026. The site is served through Cloudflare, with a domain registered 11 weeks before launch. Our crawler found 11 technologies on this site, covering advertising, analytics, CDN, and CSS frameworks. The stack includes Astro, Tailwind CSS, and Cloudflare.
It's also on one of the most common stacks we track, shared by 777 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 code-structure signals | +20 |
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.
