Nook Browser Hero

​
Rethinking browser navigation

Nook is a modern macOS browser built for the way you actually browse the web. With vertical tabs in a persistent sidebar, you get a natural, uncluttered workflow that scales from a handful of tabs to hundreds.

Why Nook?

Vertical tabs feel natural and uncluttered. Unlike horizontal tabs that get cramped and unreadable with more than a dozen open, Nook’s sidebar scales beautifully. See exactly what you have open, organize tabs into spaces and folders, and never lose track of your workflow.

​
Built for performance

Nook is optimized with modern macOS APIs for speed and low memory use. The browser uses:
  • WKWebView for native WebKit rendering
  • Swift 6 with strict concurrency for thread safety
  • Lazy webview loading to minimize memory footprint
  • Intelligent tab unloading to keep inactive tabs from consuming resources

​
Minimal, modern interface

Every pixel is focused on content, not chrome. The interface adapts to your needs:
  • Customizable sidebar position (left or right)
  • Optional top-bar address view or sidebar-integrated URL entry
  • Configurable materials and visual effects
  • Command palette for keyboard-driven navigation

​
Privacy and control

  • Multiple profiles with isolated data stores for work, personal, and testing
  • Incognito mode with non-persistent storage
  • Cross-site tracking protection (optional)
  • Extension support via WKWebExtension (macOS 15.4+)
