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 16 July 2026; the live site may have changed since.
Sandbox SDK is largely in shape, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and no email security records.
Launched on Product Hunt on July 16, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered the day of launch. The crawl picked up 9 technologies on this site, covering security, CDN, directory, and DNS providers. The stack includes Next.js, React, and Cloudflare.
For context, it's running the same core stack as 2,249 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 |
|---|---|
| Placeholder branding | +10 |
| AI copy signals | +5 |
| AI palette signals | +5 |
| AI writing signals | +3 |
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.
