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 30 July 2026; the live site may have changed since.

Alarium covers some of the launch checklist, with a thorough launch checklist and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and no email security records.

Launched on Hacker News on July 30, 2026. The site is hosted on Vercel. Our crawler found 12 technologies on this site, covering javascript library, analytics, DNS providers, and transactional email. The stack includes Next.js, React, and deck.gl.
