Open Arc is an independent, open-source browser for macOS, maintained by Stone Wang (St0neWan9) with contributions welcome on GitHub. It brings familiar Arc-style organization to a browser you can inspect and help improve.
What Open Arc offers
Spaces, nested folders, Favorites and pinned tabs keep your workspace organized. Split View, the command bar, Peek, Little Arc and automatic tab archiving support everyday browsing. You can import a supported Arc sidebar instead of rebuilding your workspace by hand.
Open Arc uses a native Swift interface and a Chromium-based web engine. The current macOS installer requires macOS 14 or later and Apple silicon. Open Arc is free to download and use; the source repository contains the code and its license.
Your data and your choices
Browsing data is stored locally. Optional workspace sync uses your private iCloud database, and no Open Arc account is required. Sync does not transfer every kind of browsing data; see what iCloud sync includes.
Basic usage analytics can be turned off in Settings. The privacy policy explains what the app connects to and what stays on your Mac.
An independent project
Open Arc is not affiliated with, endorsed by or developed by The Browser Company. It is written independently, and it does not promise complete feature parity with Arc. The feature comparison explains the similarities and current differences.
