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

PLC Lint has the basics covered well, with clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Hacker News on August 16, 2026. The site is hosted on AdminVPS - AdminVPS OOO in Russia, with a domain registered 2 weeks before launch. Our crawler found 10 technologies on this site, covering seo, analytics, DNS providers, and transactional email. The stack includes Svelte, AdminVPS, and Caddy.

It's also one of 66 launches on this exact stack.

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.
