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 8 June 2026; the live site may have changed since.
Rayline ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: no sitemap and analytics without a consent banner.
Launched on Hacker News on June 8, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 1 week before launch. The crawl picked up 30 technologies on this site, covering advertising, analytics, social embeds, and CDN. The stack includes Apple Sign In, Tailwind CSS, and Bing Ads.
For context, it's running the same core stack as 1,079 other launches and tighter on security headers than most Hacker News launches.
