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

Glassboard 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 June 18, 2026. The site is hosted on Fastly in the United States. Our crawler found 4 technologies on this site, covering CDN, DNS providers, business email, and hosting. The stack includes AWS Route 53, Fastly, and GitHub Pages.

Notably, it's running the same core stack as 1,160 other launches.
