Missing Arc Spaces in Chrome? Get Them Back in 5 Minutes

Key takeaways

• Arc entered maintenance mode May 2025. Atlassian acquired The Browser Company for $610M in September 2025; development has moved to Dia.
• Chrome has no native Spaces. Tab Groups label tabs but share the same strip: no isolation, no context switching.
• SuperchargeNavigation replicates Arc Spaces in Chrome with named workspaces, full tab isolation, Alt+K command bar, and 50-snapshot time-travel. Free, no account.

You had a Work Space, a Personal Space, maybe a Research Space. Each one held its own tabs, its own context, its own quiet. Switching between them was a single click — the rest of the browser changed around you. That was Arc Spaces. If you are on Chrome now and looking for the same thing, the short answer is: it exists, it takes five minutes to set up, and it costs nothing.

Why Chrome Does Not Have This Built In

Chrome’s Tab Groups were introduced as the browser’s answer to context separation. They are not that. A tab group is a labeled cluster on the same tab strip: all groups coexist visually, all tabs remain present simultaneously, and there is no mechanism for hiding one context while working in another. You can collapse groups, but the collapsed state does not persist reliably across sessions. You cannot press a key and move from Work mode to Personal mode with the rest of the browser adjusting accordingly.

Arc Spaces were architecturally different. Each Space was its own isolated container. When you switched from Work to Research, the Work tabs disappeared from view entirely — they were still running, still loaded, but they were not competing for your attention. The color theme changed. The sidebar contents changed. You were in a different context, not just looking at a different section of the same long list.

Chrome 149 still has no equivalent. This is not a gap that Chrome’s roadmap is addressing in the near term.

How SuperchargeNavigation Replicates Arc Spaces

SuperchargeNavigation (v1.3.1, verified live on CWS as of June 2026) provides the workspace layer that Chrome does not. The match to Arc Spaces is not incidental: the extension’s workspace model was designed for exactly this user.

Named, isolated workspaces. Each workspace in Nav holds its own tab set. When you switch from Work to Personal, the Work tabs leave the view entirely — they remain running in memory, but they are not visible and do not compete for attention. This is the Arc Spaces behavior at the functional level. You can have as many workspaces as you need; there is no paid tier or limit on workspace count.

Switching mechanics. The workspace switcher lives in the side panel. Click the workspace name to switch. For keyboard-first users: open the side panel with Alt+B, then click or arrow to the target workspace. The switch is instant — no page reload, no loading state.

Per-workspace customization. Each workspace gets an icon from a 60+ icon library (Work, Dev, Personal, Research, and more categories) and a name you set. The visual differentiation is lighter than Arc’s full theme system. There is no per-Space background color or font change, but the icon and name make workspaces identifiable at a glance in the side panel and on the new tab page workspace pills.

Session persistence and time-travel. Nav saves an automatic snapshot of your full browser state every 5 minutes, kept in a 50-entry global ring buffer. If Chrome crashes, if you accidentally close a workspace, or if you want to undo a tab cleanup from an hour ago, the snapshot list has a recoverable state. Arc users who relied on Spaces persistence will recognize this behavior: same class of accidents, same recovery path.

Cross-device sync. Workspace sync is off by default. Enable it in Settings to route workspaces through your browser’s own account sync across devices — your Google account on Chrome, your Microsoft account on Edge. This requires being signed into your browser on both machines. Chrome and Edge are separate sync islands: a workspace created in Chrome does not appear in Edge. All sync traffic goes through the browser’s own infrastructure; no data touches SuperchargeBrowser servers, and we cannot read it.

Setting Up Your First Workspace

The setup takes under five minutes.

1. Install SuperchargeNavigation from the Chrome Web Store (free, no account required).
2. Pin the extension icon in the Chrome toolbar: click the puzzle piece icon, find Nav, click Pin.
3. Open the side panel: click the Nav icon in the toolbar, or press Alt+B.
4. In the side panel, click the workspace name at the top to open the workspace menu.
5. Click New workspace and name it to match your old Arc Space names (Work, Personal, Research, etc.).
6. Open your work tabs in the Work workspace. Then switch to Personal and open those tabs there. The tabs stay in their respective workspaces from this point forward.

For users migrating from Arc, the step that most closely mirrors the Arc workflow is creating one workspace per Space you had in Arc, then moving tabs into each. Right-click any tab in the side panel → Send to workspace → select the target. Tabs move instantly.

What Is Different From Arc Spaces

The parity is close but not complete. Three things Arc did that Nav does not:

Per-Space themes. Arc applied a color theme across the full browser UI when you entered a Space: different wallpapers, different sidebar colors. Nav provides per-workspace icons and names, but the surrounding Chrome UI does not change. The functional separation is the same; the visual transformation is not.

Little Arc mini windows. Arc Spaces had a companion feature: Little Arc, which opened quick-lookup URLs in small floating windows that did not belong to any Space. There is no Chrome extension equivalent for this. It remains one of Arc’s features with no direct answer in Chrome.

Native integration. Arc Spaces were built into the shell, not running on top of it. Nav runs as an extension on top of Chrome’s standard UI. The side panel is a Chrome side panel, not a redesigned browser chrome. For users who valued how integrated Arc felt, there is a perceptible difference in how “native” the experience feels.

Everything else maps well: the named contexts, the tab isolation, the persistence, the session recovery, the command bar. If you used Arc Spaces primarily for workflow separation rather than for Arc’s aesthetic, the functional replacement is solid.

If You Also Used the Arc Command Bar

Arc’s Command Bar (Cmd+T) was central to many Arc Spaces workflows: searching across all Spaces without switching context first. Nav includes the same capability via Alt+K. The command bar searches open tabs across all workspaces, recently closed tabs, bookmarks, and browser history simultaneously. Type a fragment of any tab title; results appear in under 100ms. Arrow keys navigate, Enter opens.

For cross-workspace tab search specifically: Alt+K finds tabs regardless of which workspace they are in, which is the Arc behavior. You do not need to switch to a workspace before searching it.

The Setup Decision

The path forward from Arc Spaces depends on what you actually needed from them:

• If workspace separation and tab isolation were the core value — SuperchargeNavigation covers this directly. Free install, no account, five-minute setup.
• If Arc’s full aesthetic (themes, wallpapers, Little Arc) was equally important — the closest overall-experience match is Zen Browser, but it is Firefox-based. Chrome extensions cannot run in Firefox. If you stay on Chrome, the aesthetic parity is partial.
• If you used Arc Spaces with Arc’s built-in notes, media library, or Boosts — those features require separate extensions (Notion or Keep for notes, Stylus for CSS customization). Nav does not include them.
• If cross-device sync is a priority — Nav’s opt-in sync (via your browser’s own account sync, Settings toggle) handles this. Requires browser sign-in on both devices. Chrome and Edge sync separately.

Arc entered maintenance mode May 2025 (12 months before this article’s May 2026 publication). The team has moved to Dia. Waiting for Arc to return is not the practical path. The workflow is rebuildable in Chrome today, with tools that are actively maintained.

SuperchargeNavigation v1.3.1 is free, zero telemetry, no account required. The workspace separation Arc users built their workflows around is available today.
