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 8 May 2026; the live site may have changed since.
QuickCalc Tools is largely in shape, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and no email security records.
Launched on Product Hunt on May 8, 2026. The site is hosted on Vercel. The crawl picked up 7 technologies on this site, covering AI builders, CSS frameworks, developer tools, and hosting. The stack includes Tailwind CSS, Google Search Console, and HSTS.
For context, it's running the same core stack as 3,182 other launches.

| AI writing signals | +5 |
| Recognised AI builder signature | +100 |

| 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.
