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 21 August 2026; the live site may have changed since.

Rotation via Double Reflection is early-stage. Worth fixing first: missing Permissions-Policy and Content-Security-Policy, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on August 21, 2026. The site is hosted on uvensys GmbH in Germany. We've detected 5 technologies on this site, covering frameworks, javascript library, meta-frameworks, and security. The stack includes Svelte, SvelteKit, and HSTS.

It's one of 80 launches on this exact stack and tighter on security headers than most Hacker News launches.
