Screenshot of Lume

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.

Lume is early-stage. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on June 29, 2026. The site is hosted on Vercel. We've detected 5 technologies on this site, covering documentation, frameworks, hosting, and meta-frameworks. The stack includes Astro, Svelte, and HSTS.

It's one of just 2 launches we've crawled on this exact stack.

SignalPoints
AI copy 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.
