404love Next.js App Router

Provide drop-in 404 pages that replace dead ends with adoptable pets. Use the @404love/next SDK to render a full-page, accessible 404 experience (powered by the 404found iframe) in Next.js App Router projects.

Highlights

• Privacy-respecting: no cookies, no tracking, no PII. Only optional referer query param for back navigation.
• Content-safe: only adoptable pets, no user-generated content.
• Accessible, tested 404 experience with built-in back navigation.
• Lightweight iframe embed that keeps the host site in control.

Requirements

• Use Next.js 13.4+ with App Router.
• Use React 18+.
