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 6 July 2026; the live site may have changed since.
ReplyFlow is partway there, with a thorough launch checklist and fast page loads. Worth fixing first: missing several security headers, incomplete legal pages, and no sitemap.
Launched on Product Hunt on July 6, 2026. The site is served through Cloudflare, with a domain registered 11 months before launch. The crawl picked up 10 technologies on this site, covering javascript library, ui library, AI builders, and CDN. The stack includes Tailwind CSS, Cloudflare, and Hercules.
For context, it's running the same core stack as 5,454 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 CSS signals | +10 |
| Recognised AI builder signature | +100 |
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.
