crowfly.golf · Added June 12, 2026 · Last analysed June 12, 2026 · via Hacker News · 77% unique tagline

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.

Crowfly.golf is missing several launch fundamentals. Main gaps: 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 Fastly in the United States, with a domain registered 1 week before launch. Our crawler found 6 technologies on this site, covering CDN, DNS providers, business email, and web fonts. The stack includes Fastly, GitHub Pages, and Google Fonts.

Notably, it's on one of the most common stacks we track, shared by 1,049 launches.
