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 10 August 2026; the live site may have changed since.
Halcyon is largely in shape, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and no email security records.
Launched on Product Hunt on August 10, 2026. The site is served through Cloudflare, with a domain registered in 2023. The crawl picked up 14 technologies on this site, covering analytics, security, ui library, and AI builders. The stack includes Tailwind CSS, TanStack Start, and Cloudflare.
For context, it's running the same core stack as 877 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 writing signals | +5 |
| Recognised AI builder signature | +100 |
| AI typography signals | +5 |
| 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.
