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 28 June 2026; the live site may have changed since.
Echo - Mobile AI Voice Changer looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
Launched on PeerPush on June 28, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 5 months before launch. We've detected 17 technologies on this site, covering analytics, auth, CDN, and CSS frameworks. The stack includes Auth.js, Next.js, and React.
It's running the same core stack as 8,742 other launches.
