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 5 June 2026; the live site may have changed since.
Invariant.dev looks production-ready overall, with complete legal pages, a thorough launch checklist, and fast page loads. Main gaps: missing several security headers and no email security records.
Launched on Product Hunt on June 5, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 3 days before launch. We've detected 7 technologies on this site, covering CSS frameworks, DNS providers, frameworks, and hosting. The stack includes Next.js, React, and Tailwind CSS.
It's on one of the most common stacks we track, shared by 6,672 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 |
| Unfilled template placeholders | +10 |
| Default scaffold favicon | +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.
