An Arc alternative that keeps your Spaces.

Arc stops working on December 22, 2026. Acira is a browser for Windows, Mac and Linux that imports your Spaces as workspaces and your Favorites to the top of the sidebar, so you don't have to rebuild everything.

Beta for Windows, Mac and Linux

What comes over from Arc

From ArcIn Acira
SpacesWorkspaces, each with its name, emoji and color. A profile holds up to eight, and any beyond that become collapsed tab groups.
Pinned tabsThey stay pinned in their workspace. Each folder becomes a collapsed tab group. Up to 200 tabs come over, and they load only when you open them.
FavoritesThe top of the sidebar, up to 24.
BookmarksAdded with their folders, plus a folder called Arc with your pinned tabs and folders for each Space.
HistoryYour 50,000 most recent visits.

Sign-ins do not come across. Acira helps you sign back in, and you can bring passwords from a file you export.

What will feel familiar

  • Tabs in a sidebar. Turn them on in Settings › Appearance › Layout. Favorites sit at the top.
  • Split view with up to four panes.
  • Link previews. Alt-click a link to look at it without leaving your page.
  • Command search. Press Ctrl+Shift+K to find a tab or run a command.
  • Just the page. Focus and Seamless views hide the browser until you point at an edge.
