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 10 April 2026; the live site may have changed since.

Contrapunk still has work before launch. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on April 5, 2026. The site is hosted on GitHub Pages and served through Fastly. The crawl picked up 7 technologies on this site, covering analytics, CDN, DNS providers, and business email. The stack includes Astro, Cloudflare DNS, and Fastly.

For context, it's one of 30 launches on this exact stack.
