Arc vs Chromium

Arc is a Chromium-based web browser developed by The Browser Company that reimagines the browser interface with features like Spaces for organizing tabs, a sidebar-first design, and built-in tools for capturing and annotating web content.

Chromium is the open-source web browser project that forms the foundation for Google Chrome, Microsoft Edge, Brave, and many other browsers. It provides the Blink rendering engine, V8 JavaScript engine, and a multi-process architecture.
