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 5 June 2026; the live site may have changed since.

Wallflower.app looks production-ready overall, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and no email security records.

Launched on Hacker News on June 4, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 1 day before launch. We've detected 5 technologies on this site, covering analytics, CDN, DNS providers, and meta-frameworks. The stack includes SvelteKit, Cloudflare, and Cloudflare DNS.

It's one of just 20 launches we've crawled 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.
