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 29 April 2026; the live site may have changed since.

notclass ships with the basics, 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 April 29, 2026. The site is hosted on Vercel, with a domain registered in 2024. We've detected 7 technologies on this site, covering DNS providers, web fonts, frameworks, and hosting. The stack includes Next.js, React, and Fontshare.

It's running the same core stack as 2,298 other launches.
