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 12 August 2026; the live site may have changed since.
Founder Validation OS is partway there, with complete legal pages and well-configured email security. Worth fixing first: missing several security headers and no robots.txt or sitemap.
Launched on Product Hunt on August 12, 2026. The site is served through Cloudflare. The crawl picked up 35 technologies on this site, covering payments, social embeds, advertising, and analytics. The stack includes Inertia.js, Tailwind CSS, and Vue.js.
For context, it's one of 29 launches on this exact stack.

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 iconography signals | +5 |
| Unfilled template placeholders | +10 |
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.
