Browsers with Workspaces Like Arc
Arc made “Spaces” feel obvious—color-coded contexts, a vertical sidebar, and zero tab chaos. These browsers carry that DNA in 2026. Filter by what you miss from Arc, then see why Tabbit adds AI execution on top.
What you miss from Arc
What Arc Spaces actually gave you
Most listicles skip this. Arc users rarely want “another browser”—they want three habits back.
Vertical tab shelf
Full titles, drag-to-reorder, and a sidebar that stays out of the URL bar’s way—especially on laptops.
Profile-level isolation
Different logins and extensions per space so Slack in “Work” never leaks into “Weekend research.”

From Spaces to execution
Why Tabbit is the Arc upgrade
Tabbit keeps the workspace muscle memory—vertical tabs, smart groups, one-click context switches—then adds Agent Mode so research and form-filling run in parallel while you stay in flow.
AI smart groups
Open twenty tabs; Tabbit clusters them by topic like Arc Spaces—but the groups stay live and searchable.
Agent in isolated tab groups
Delegate a research or data task to an agent that works in its own group without hijacking your current space.
Zero migration friction
Import bookmarks, passwords, and extensions from Chrome or Arc in minutes—no invite code required.
Free on Windows & Mac
Top models included internationally; domestic build ships DeepSeek, Qwen, Kimi, and more—no paywall for workspaces.
Arc workspace FAQ
Questions Arc migrants ask
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.
