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 28 July 2026; the live site may have changed since.
Studycardsai is largely in shape, with complete legal pages and a thorough launch checklist. Worth fixing first: missing Permissions-Policy and Content-Security-Policy, no sitemap, and no email security records.
Launched on Hacker News on July 28, 2026. The site is hosted on Heroku, with a domain registered in 2024. The crawl picked up 17 technologies on this site, covering analytics, frameworks, package cdn, and video. The stack includes Alpine.js, Stimulus, and Tailwind CSS.
For context, it's a rare Stimulus sighting, just 48 in our data and tighter on security headers than most Hacker News launches.

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 code-structure 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.
