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 June 2026; the live site may have changed since.

Open-Source Legends is early-stage. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on June 21, 2026. The site is hosted on Railway in the United States, with a domain registered the day of launch. We've detected 5 technologies on this site, covering DNS providers, frameworks, hosting, and meta-frameworks. The stack includes Next.js, React, and CrawlProof.

It's one of 56 launches on this exact stack.
