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.

CodePLU looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on April 4, 2026. The site is served through AWS CloudFront, with a domain registered in 2022. We've detected 12 technologies on this site, covering advertising, analytics, CDN, and cloud. The stack includes SvelteKit, Tailwind CSS, and Amazon Web Services.

It's one of 69 launches on this exact stack.

SignalPoints
AI palette signals +5

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
