Zen Browser
Calm, open-source browser with vertical tabs
SoftwareProductivity
Zen is a free, open-source browser based on Firefox, built around a vertical tab sidebar, workspaces, and split view. It is the closest open-source match to Arc's layout.
Key Features:
- Vertical tabs with pinned Essentials and Workspaces.
- Split view for up to four tabs side by side.
- Compact mode hides the toolbar for a clean window.
- Glance opens links in a quick preview.
- Supports Firefox add-ons and Mozilla privacy features.
Zen suits people who loved Arc's sidebar and want an open-source, community-built browser.
