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 3 July 2026; the live site may have changed since.
Haven PDF ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. What needs work: no email security records.
Launched on Product Hunt on July 3, 2026. The site is served through Cloudflare, with a domain registered 4 weeks before launch. Our crawler found 10 technologies on this site, covering analytics, CDN, CSS frameworks, and developer tools. The stack includes Capacitor, Tailwind CSS, and Cloudflare.
It's also on a stack we've seen on only 17 launches and tighter on security headers than most Product Hunt 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 palette signals | +5 |
| AI writing 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.
