Score: 5.8/10 (Innovation: 3, Technical: 7, Documentation: 8, Utility: 5)

Radian is a macOS Electron-based Chromium browser that aims to replicate the look, feel, and workflow of Arc Browser, including its sidebar, Spaces, Command Bar, and theming. It is built as a fork of the MIT-licensed Orbe project, with Arc-parity work measured by observing Arc's behavior rather than reusing its code or assets. The project fills a niche gap for Arc users seeking an open-source alternative, though it is still early and lacks signed builds.

Target audience: macOS users, Arc Browser refugees, frontend and Electron developers
