PRISM — Learn System Design

Practice, Learn and Evaluate System Design Interviews

Education

Added June 29, 2026 · Last analysed June 29, 2026 · via · 33% unique tagline (similar to Scalcraft)

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

PRISM — Learn System Design is largely in shape, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: no robots.txt or sitemap and incomplete email security.

Launched on Product Hunt on June 29, 2026. The site is hosted on Render and served through Cloudflare, with a domain registered 1 week before launch. The crawl picked up 10 technologies on this site, covering analytics, DNS providers, CDN, and web fonts. The stack includes Cloudflare, Cloudflare DNS, and GoDaddy DNS.

For context, it's running the same core stack as 371 other launches and tighter on security headers than most Product Hunt launches.
