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 11 April 2026; the live site may have changed since.

Agent Browser looks production-ready overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Worth fixing first: missing several security headers.

Launched on Product Hunt on April 9, 2026. The site is hosted on IONOS, with a domain registered 4 weeks before launch. We've detected 13 technologies on this site, covering transactional email, hosting, advertising, and analytics. The stack includes Next.js, React, and Tailwind CSS.

It's one of 92 launches on this exact stack.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
