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 21 August 2026; the live site may have changed since.

Mercury is partway there, with clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on August 21, 2026. The site is hosted on Amazon.com in the United States. The crawl picked up 5 technologies on this site, covering frameworks, DNS providers, and security. The stack includes Angular, Capacitor, and Ionic Framework.

For context, it's one of only 35 launches we've crawled running Ionic Framework.
