ColdVisit
An AI agent tests your journey from landing page to first value, showing where the experience becomes unclear, difficult, or impossible.
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 19 August 2026; the live site may have changed since.
ColdVisit is largely in shape, with complete legal pages, a thorough launch checklist, and well-configured email security. Visible gaps: missing several security headers and tracking cookies set before any opt-in.
Launched on PeerPush on August 19, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 4 weeks before launch. The crawl picked up 18 technologies on this site, covering analytics, security, auth, and CDN. The stack includes Clerk, Next.js, and React.
For context, it's on one of the most common stacks we track, shared by 3,041 launches.
