Seven names people actually compare when searching “browsers with workspaces like Arc.” Filter above to narrow the wall.

Z
Zen Browser
Firefox workspaces + sidebar
Windows, macOS & Linux
Community favorite after Arc—Firefox-based with Workspaces, vertical tabs, and a calm default theme. No built-in AI agent.

S
SigmaOS
Mac “islands” like Spaces
macOS-first
Spatial layout with workspace islands and AI sidebar. Feels Arc-adjacent but Mac-only and account-gated for sync.

V
Vivaldi
Named workspaces + stacks
Windows, macOS & Linux
Power-user classic—native Workspaces, tab stacks, and deep customization. Steeper learning curve than Arc was.

Floorp
Firefox workspaces clone
Windows, macOS & Linux
Reddit’s frequent answer—Firefox fork with Workspaces, vertical tabs, and tree-style tabs. Great if you want Gecko + Arc vibes.

macOS · invite/waitlist
Successor energy from Arc’s makers—conversation-first UI with shared contexts. Limited platform reach vs Tabbit today.

The benchmark everyone compares against—Spaces, Little Arc, and Boosts. Not a forward-looking pick in 2026.

Questions des migrants Arc
Which browser is most like Arc Spaces?+
Zen Browser and Floorp mirror Arc’s workspace + vertical sidebar combo on Firefox. Tabbit matches the organization feel and adds AI smart groups plus Agent Mode on Chromium—for both Windows and macOS.
Is Zen Browser a good Arc replacement?+
Yes for layout purists—Workspaces, vertical tabs, and open-source development. It lacks Arc’s polish and any native AI agent; pair it with extensions or switch to Tabbit if you want execution, not just grouping.
Does SigmaOS work like Arc on Windows?+
No—SigmaOS is macOS-first. Windows users should look at Tabbit, Vivaldi, Floorp, or Zen instead.
Can Tabbit import my Arc profile?+
Tabbit imports from Chrome, Edge, and Safari—including bookmarks, passwords, history, and extensions. Export Arc to Chrome first, then one-click import into Tabbit.
Are browsers with workspaces like Arc free?+
Zen, Floorp, and Vivaldi are free. Tabbit is free without invite codes. SigmaOS and Dia offer freemium or waitlist tiers.
What happened to Arc Browser?+
The Browser Company shifted focus; Arc is in wind-down for new users. That’s why “browsers with workspaces like Arc” spiked—people want Spaces elsewhere.
Do I need vertical tabs for Arc-like workspaces?+
Not strictly—Vivaldi uses horizontal tabs with workspaces. Most Arc fans expect a sidebar though; Tabbit, Zen, and Floorp all ship vertical tab layouts.
Is Dia the official Arc successor?+
Dia comes from the same company but targets AI conversation workflows, not a 1:1 Spaces clone. For cross-platform Arc-style workspaces today, Tabbit is the stronger default.
