Orbe
Free, open-source Arc-style sidebar browser in French and English, on Electron (Chromium), Mac and Windows.
Orbe is a solo-built sidebar browser that copies Arc's organization and keyboard shortcuts: Spaces with per-Space themes, favorites, pinned tabs and folders, a command bar, up to four split panes, Peek, Little window, Boosts and Zap. It is a JavaScript app on Electron (Chromium 152). It imports Arc spaces, pinned tabs, folders, favorites and profiles from a local Arc install. The UI is French first with English in Settings. The Mac build is ad-hoc signed (macOS asks for confirmation), has no Widevine, and does not support passkeys or sync. The Windows build is only tested in CI.
76% Arc feature parity (yes = 1, partial = ½).
