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 1 May 2026; the live site may have changed since.

Free Online Audio Mastering Tool is partway there, with clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on May 1, 2026. The site is hosted on HETZNER-AS in Germany, with a domain registered in 2021. The crawl picked up 4 technologies on this site, covering DNS providers, business email, seo, and servers. The stack includes Directnic, Google Search Console, and Google Workspace.
