Own this Launch?

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 12 June 2026; the live site may have changed since.

Arcadia still has work before launch. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on June 12, 2026. The site is hosted on Amazon.com in the United States. The crawl picked up 4 technologies on this site, covering frameworks, hosting, meta-frameworks, and security. The stack includes Next.js, React, and HSTS.

For context, it's running the same core stack as 1,436 other launches.
