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 16 July 2026; the live site may have changed since.

Murmur is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and incomplete email security.

Launched on Product Hunt on July 16, 2026. The site is hosted on GitHub Pages and served through Fastly, with a domain registered 1 week before launch. The crawl picked up 11 technologies on this site, covering CDN, CSS frameworks, DNS providers, and email forwarding. The stack includes Next.js, React, and Tailwind CSS.

For context, it's one of 32 launches on this exact stack.
