O que você sente falta do Arc

Seven names people actually compare when searching “browsers with workspaces like Arc.” Filter above to narrow the wall.
AI smart groups + vertical tabs
Windows & macOS · free
Closest upgrade path: Arc-style grouping plus Agent Mode that runs tasks in parallel tab groups while you keep browsing.
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.
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.
Named workspaces + stacks
Windows, macOS & Linux
Power-user classic—native Workspaces, tab stacks, and deep customization. Steeper learning curve than Arc was.
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.
AI-first from Browser Company
macOS · invite/waitlist
Successor energy from Arc’s makers—conversation-first UI with shared contexts. Limited platform reach vs Tabbit today.
Original Spaces reference
macOS · winding down
The benchmark everyone compares against—Spaces, Little Arc, and Boosts. Not a forward-looking pick in 2026.
Quick scan before you reinstall another sidebar. Green checks are “good enough for most Arc migrants.”

FAQ espaços Arc
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.
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.
No—SigmaOS is macOS-first. Windows users should look at Tabbit, Vivaldi, Floorp, or Zen instead.
Tabbit imports from Chrome, Edge, and Safari—including bookmarks, passwords, history, and extensions. Export Arc to Chrome first, then one-click import into Tabbit.
Zen, Floorp, and Vivaldi are free. Tabbit is free without invite codes. SigmaOS and Dia offer freemium or waitlist tiers.
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.
Not strictly—Vivaldi uses horizontal tabs with workspaces. Most Arc fans expect a sidebar though; Tabbit, Zen, and Floorp all ship vertical tab layouts.
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.
