## What it is
Nook is a fast, minimal web browser for macOS built in Swift with a sidebar-first, vertical-tab design. It is a native macOS application distributed as a DMG and buildable from source with Xcode.

## Use cases
- browse the web with vertical sidebar tabs on mac
- find a minimal lightweight browser for macOS
- replace Safari with a fast open-source browser
- build a custom web browser from source in Swift
- reduce browser chrome and focus on web content

## When to choose
- you use macOS 15.5+ and want a minimal, sidebar-first browser
- you prefer native Swift apps with low memory usage
- you want an open-source (GPL-3.0) browser you can build and modify

## When to avoid
- you need a cross-platform browser on Windows or Linux
- you rely on extensive extension ecosystems like Chrome's
- you need enterprise features such as managed policies or sync across devices
- you're on an Intel Mac, where some Objective-C libraries may have build issues
