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 25 August 2026; the live site may have changed since.
Errorcore ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and clean crawl signals. Worth fixing first: no email security records.
Launched on Product Hunt on August 25, 2026. The site is hosted on Railway and served through Cloudflare, with a domain registered 5 months before launch. We've detected 16 technologies on this site, covering security, ui library, auth, and captcha. The stack includes Clerk, Next.js, and React.
It's running the same core stack as 124 other 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 copy signals | +5 |
| AI palette 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.
