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

AltCatalog scores highly overall, with complete legal pages, a thorough launch checklist, and fast page loads. Main gaps: missing several security headers and incomplete email security.

Launched on PeerPush on August 25, 2026. The site is hosted on DigitalOcean App Platform and served through Cloudflare, with a domain registered 6 weeks before launch. The crawl picked up 10 technologies on this site, covering DNS providers, frameworks, CDN, and business email. The stack includes Alpine.js, htmx, and Cloudflare.

For context, it's the only launch we've crawled on this exact stack.

AI writing signals +3

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.
