Radian Browser

Radian Browser is an independent open-source Chromium-based browser for macOS (Apple Silicon) designed to replicate the look, feel, and workflow of the Arc browser. It features a sidebar with Spaces, favorites, pinned tabs, command bar, split view, themes, Easels (infinite canvases for notes and media), built-in ad and tracker blocking, extension support, and shortcuts modeled after Arc. Radian aims to serve users who relied on Arc after its shutdown announcement, providing a free and open alternative without AI features, account sync, or telemetry.
