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 May 2026; the live site may have changed since.

Otter A/B ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing Permissions-Policy and Content-Security-Policy, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on May 19, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 7 weeks before launch. Our crawler found 15 technologies on this site, covering analytics, backend framework, advertising, and CSS frameworks. The stack includes Tailwind CSS, Facebook Pixel, and Google Analytics.

It's also running the same core stack as 7,400 other launches and tighter on security headers than most Product Hunt launches.
