Own this Launch?

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

Whisper Web UI has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers, tracking cookies set before any opt-in, and no email security records.

Launched on Product Hunt on August 4, 2026. The site is hosted on OpenNext and served through Cloudflare, with a domain registered 11 months before launch. Our crawler found 28 technologies on this site, covering directory, analytics, seo, and baas. The stack includes Next.js, React, and AgentHunter.

It's also on one of the most common stacks we track, shared by 112 launches.
