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 20 July 2026; the live site may have changed since.

Headroom is missing several launch fundamentals. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on July 20, 2026. The site is hosted on GitHub Pages and served through Fastly. Our crawler found 3 technologies on this site, covering CDN, hosting, and security. The stack includes Fastly, GitHub Pages, and HSTS.

It's also running the same core stack as 1,847 other launches.
