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 9 June 2026; the live site may have changed since.
OpenSign is early-stage. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.
Launched on Product Hunt on June 9, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 5 days before launch. We've detected 6 technologies on this site, covering build tooling, CSS frameworks, DNS providers, and hosting. The stack includes Tailwind CSS, Vite, and HSTS.
It's running the same core stack as 1,456 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 copy signals | +5 |
| AI iconography 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.
