TL;DR
No mainstream browser has Arc's everyday habits as a set. Checked habit by habit in Chrome, Safari, Brave, Firefox and Edge, only 1 of 45 checks is a full match (Firefox's option to make Ctrl+Tab jump back to your last tab), and none of the five has Little Arc. Safari comes closest, with partial matches on 7 of the 9 habits. Among Arc-style browsers, Zen has Spaces and Glance, its version of Peek, but no Little Arc, and Dia has no Little Arc, Peek or Air Traffic Control. SupaSidebar is a Mac app that docks Arc's sidebar beside the browser you already use, and it covers all nine habits in any of these browsers before Arc stops working on December 22, 2026.

Which browsers have Arc features, habit by habit
Chrome, Safari, Brave, Firefox and Edge each copy a few Arc features, mostly the ones that live in the tab strip, and none of them copies the habits that reach outside the browser. The table checks nine Arc habits against each browser's own help pages and release notes as of November 6, 2026. "Yes" means the browser does it natively, "Partly" means a weaker version, and "No" means nothing built in.
| Arc habit | Chrome | Safari | Brave | Firefox | Edge | SupaSidebar |
|---|---|---|---|---|---|---|
| Sidebar and Spaces | Partly, vertical tabs | Partly, vertical tabs in beta | Partly, vertical tabs | Partly, vertical tabs | Partly, Workspaces | Yes, Spaces in a sidebar |
| Pinned tabs and Favorites | Partly, pinned tabs | Partly, pinned tabs | Partly, pinned tabs | Partly, pinned tabs | Partly, pinned tabs | Yes, pins per Space or for all |
| Cmd+T command bar | Partly, address bar | Partly, tab search | Partly, address bar | Partly, address bar | Partly, address bar | Yes, Command Panel |
| Ctrl+Tab to your last tab | No | No | No | Yes, one setting | No | Yes, Tab Switcher |
| Little Arc | No | No | No | No | No | Yes, SupaView |
| Peek | No | Partly, Force Click | No | No | No | Yes, SupaView |
| Air Traffic Control | No | Partly, site to profile | No | No | Partly, site to profile | Yes, Air Traffic Control |
| Links from other apps | No | Partly, last profile | No | No | Partly, one default profile | Yes, SupaView or a rule |
| Auto-archive | No, tabs sleep | Partly, closes after a day | No | No | No, tabs sleep | Yes, Archived Tabs |
Across the 45 checks, 1 is a full match, 21 are partial and 23 are missing. Safari has the most partial matches of the five (7 of 9), Edge has 5, and Chrome, Brave and Firefox have 3 each, with Firefox adding the one full match. The pattern holds across every browser. They copied the parts of Arc that sit inside one window, and the parts that work across apps, like Little Arc and a Ctrl+Tab that knows every browser, stayed missing.
Does any browser have Arc's sidebar and Spaces?
Every browser in this check now has vertical tabs, but none of the five has Arc's Spaces, separate sets of tabs you switch inside one sidebar. Edge comes closest with Workspaces. Among Arc-style browsers, Zen has real Spaces and Dia replaced them with profiles.
Chrome
added vertical tabs on April 7, 2026, per Google's own announcement. They list the tabs open right now, so separate contexts still live in profiles, each in its own window. The full breakdown is in Chrome Vertical Tabs vs Arc Sidebar.
Safari
has had Tab Groups in its sidebar for years, and vertical tabs arrived in the first macOS 27.3 developer beta on November 3, 2026, per Six Colors. Tab Groups work in the new layout, and Apple expects 27.3 to reach everyone in December, per 9to5Mac. A Tab Group swaps which tabs you see, which is the closest Safari gets to a Space.
Brave
has had vertical tabs for a while, but Workspaces is still an unfinished feature that ships turned off, tracked in Brave's own issue tracker. So making Brave look like Arc gets you the tall tab list, not Spaces. Does Brave Have Workspaces? covers what Brave has today.
Firefox
shipped vertical tabs in Firefox 136 on March 4, 2025 and tab groups in Firefox 138 on April 29, 2025. In November 2025 Mozilla still listed workspaces as an open question it was asking users about, in its tab groups update. So there are no Spaces like Arc in Firefox yet.
Edge
has supported vertical tabs on macOS since version 88, per Microsoft's VerticalTabsAllowed policy page, and its Workspaces are named sets of tabs you reopen together. Workspaces need you signed in with a Microsoft or work account, per Microsoft's Workspaces guide, and Microsoft removed their sharing option in Edge 149 and 150, per the Edge release notes archive.
Zen
has Arc-style Spaces in its sidebar, and each one can have a default container, so a Space keeps its own sign-ins, per Zen's Workspaces guide. Dia has no Spaces. It uses Profiles instead, and its recent updates added swiping between Profiles, per the Dia changelog. The trade-offs are in Zen vs Arc and How to Migrate from Arc to Dia.
What the big five still lack
is a set of Spaces you switch inside one sidebar, each tied to the right browser or profile, that works the same in any browser you open. SupaSidebar keeps Arc's sidebar as a Mac app docked beside the browser window, with Spaces that can each link to a browser profile and sync to your other Macs through iCloud.
Pinned tabs exist everywhere, Arc's Favorites don't
All five browsers pin tabs, but none has Arc's two layers of pins, Favorites that stay on top in every Space and pinned tabs that belong to one Space. Arc's pins also stayed in the sidebar after you closed them, more like bookmarks than tabs.
Chrome's pinned tabs "only show the site's icon" and belong to one window, per Chrome's tab help. Safari goes further, since a pinned tab shows up in every Safari window and stays after a restart, per Apple's Safari guide. Brave, Firefox and Edge pin tabs the same basic way. Close a pinned tab in any of them and it is gone until you pin it again.
What's missing
is pins that change with the Space, plus a set that stays on top everywhere. SupaSidebar's pins show in every Space by default, like Arc's Favorites, or per Space, like Arc's pinned tabs. A saved link also lights up while its page is your current tab, the way an Arc pin did.
The Cmd+T command bar in other browsers
No browser has Arc's command bar, but all five can find a tab you already have open, which covers part of it. In Arc, Cmd+T opened the command bar instead of a blank tab, and one box searched tabs, history and Arc's own actions.
Chrome's address bar searches only open tabs when you type @tabs first, per Google's announcement of address bar search modes. Brave and Edge, built on the same Chromium code, also suggest open tabs from the address bar. In Firefox, typing % and a space in the address bar limits the search to open tabs, per How-To Geek. Safari's Tab Overview has its own search box for open tabs, per How-To Geek's Safari guide.
What's missing
is one box that opens on Cmd+T and searches tabs in every browser at once, along with saved links and history. SupaSidebar's Command Panel opens on ⌘T in Safari, Chrome, Firefox or any other supported browser once its browser key is on, and it finds open tabs across browsers, saved links, files, history and settings. Outside a browser, ⌘⌃K opens it from any app.
Ctrl+Tab to your last tab works natively in Firefox only
Firefox is the only one of the five that can make Ctrl+Tab jump back to the tab you were just on, through a single setting. Chrome, Brave, Edge and Safari step to the next tab in the strip instead.
In Arc, Ctrl+Tab flipped to your last tab, and holding Ctrl went further back, per Arc's multitasking guide. Safari lists Control-Tab as "Go to the next tab" in Apple's shortcut list. Chrome's shortcut list for Mac only offers next and previous tab, and Brave and Edge follow Chrome. Firefox has the setting "Ctrl+Tab cycles through tabs in recently used order", documented in Mozilla's tab settings help. Every browser's tab keys are listed in Keyboard Shortcuts to Switch Tabs in Every Browser.
What's missing
is one switcher that knows your recent tabs in every browser. SupaSidebar's Tab Switcher brings back Arc's Ctrl+Tab. Tap it to return to your last tab, or hold Ctrl to pick from your 5 most recent tabs, shown as cards like Arc, even when they sit in different browsers. It lists the tabs you have visited while SupaSidebar is running.
Little Arc has no match in Zen, Dia or the big five
No browser checked here has Little Arc. Little Arc was Arc's small window for links you clicked in other apps, so a link from Slack or Mail opened without pulling you into the full browser, per Arc's multitasking guide.
Zen doesn't have Little Arc. Zen's Glance opens a link in a floating preview, but Zen's Glance guide describes it only for links clicked inside Zen. "Links from other desktop applications open in a full tab in Zen," wrote one Arc user who moved to Zen, in a June 2025 migration write-up.
Dia doesn't have Little Arc either. The Browser Company's own Arc sunset FAQ lists Little Arc among the Arc features Dia lacks, along with Peek, Air Traffic Control, Boosts and Easels. In Chrome, Safari, Brave, Firefox and Edge, a link from another app opens as a normal tab in a full window.
What's missing everywhere
is a small window for outside links. SupaSidebar's SupaView is its Little Arc. Make SupaSidebar your default browser and links from Slack, Mail, Messages or Terminal open in a small floating window, as do web searches from Raycast, Alfred or Spotlight, per the SupaView docs. SupaView is its own WebKit window with its own sign-ins, and it can import logins from your browser so sites open signed in.
Peek survives in Zen's Glance and Safari's Force Click
Zen's Glance is the closest match to Arc's Peek, and Safari previews a link when you Force Click it on a trackpad. Chrome, Brave, Edge and Firefox have no preview window in their regular settings.
In Arc, clicking a link to another site from a pinned or Favorite tab opened it in Peek, a preview over the page, per Arc's Peek help article. Zen copies that almost exactly. In Essentials and pinned tabs, Glance opens on its own for links to other sites, and Alt-click (Option on a Mac) opens it anywhere else, per Zen's Glance guide.
Safari previews a link's page when you Force Click it, per Apple's Safari guide, which needs a Force Touch trackpad. Firefox Labs added AI link previews in Firefox 139, per Mozilla's blog, but that card summarizes a page rather than opening it.
What the big five lack
is a preview you can use like a real page. In SupaSidebar, ⌘-click a link in the sidebar or press ⌘Return on a Command Panel result, and SupaView opens it in its own floating window, one window per link. Links you click inside a web page stay in your browser.
Air Traffic Control has only partial copies
Safari and Edge are the only ones of the five that can tie a site's links to a chosen profile. Chrome, Brave and Firefox have no per-site routing in their settings.
Arc added Air Traffic Control on May 3, 2023 (V0.102), routing links to a Space by their domain, per the Arc 2023 release notes. Safari's version is Open Links With Profile, which "works only with links opened from outside of Safari", per Apple's profiles guide. Edge's automatic profile switching can remember which profile a site belongs to, per Microsoft's profile switching site list policy. Both route to a profile inside the same browser.
Among Arc-style browsers, Zen added Space Routing on June 11, 2026, which sends links to a chosen Space, per its 1.21b release notes. Dia has no Air Traffic Control, per the Arc sunset FAQ.
What's missing
is rules that cover links from the sidebar and from other apps, and that can pick any browser, not just a profile inside one. SupaSidebar's Air Traffic Control sends links by URL to the browser or profile you choose, so every figma.com link can open in Chrome's Work profile while the rest open in Safari. Its save routes also file pages you save into the right Space.
Where a link from Slack or Mail lands
Safari and Edge let you steer links from other apps toward a profile, and Chrome, Brave and Firefox have no setting for it. Arc sent those links to Little Arc, or with Air Traffic Control, straight into the right Space.
Safari opens outside links in "the profile used most recently" unless a site has its own rule, per Apple's profiles guide. Edge has a "Default profile for external links" option in its profile preferences, per Microsoft's external links policy page, so outside links go to one profile you pick.
What's missing
is a choice per link. Once SupaSidebar is your default browser, every link from another app goes to SupaView or, if you set links to open in a browser, to the browser and profile an Air Traffic Control rule picks. Holding ⌘⌥ while clicking sends a link the other way.
Auto-archive, tabs that close themselves
Safari is the only one of the five that closes old tabs on its own, and its shortest timer is one day. Chrome, Brave, Firefox and Edge never close a tab for you, and Chrome and Edge only put idle tabs to sleep.
Arc moved tabs you hadn't touched for 12 hours into its archive, starting with the December 1, 2021 update in the Arc 2021 release notes. Safari's "Automatically close tabs" offers one day, one week or one month, per Apple's tabs settings guide. Chrome's Memory Saver frees memory from inactive tabs without closing them, and Edge's sleeping tabs kick in after 15 minutes by default from Edge 152, per the Edge release notes.
What's missing
is a 12-hour timer and an archive to reopen from. SupaSidebar's Archived Tabs closes tabs you stop using after 12 hours by default and keeps them for 30 days, ready to reopen with one click. One set of rules covers Safari, Chrome, Brave, Edge and the other browsers Live Tabs reads, and locked tabs stay open. It can't tell when a background tab is playing audio, so lock a music tab you want to keep.
Split View, Boosts and Easels
Three more Arc features sit outside the nine habits, and two of them have no replacement anywhere. Split View is the one other browsers copied. Chrome added split view in February 2026, per MacRumors, and Brave has one too, per Brave's help center.
SupaSidebar's version is Window Tiling. Set the sidebar to auto-tile browser windows when it opens, and up to 4 windows line up as equal columns beside it. They are separate windows, not split tabs in one window.
Boosts, which restyled websites with your own code, and Easels, Arc's whiteboards, have no SupaSidebar match. Boosts live inside the browser engine, so no app beside the browser can bring them back.
How SupaSidebar covers all nine habits in any browser
SupaSidebar covers all nine habits in Safari, Chrome, Brave, Firefox, Edge and the rest of its 32+ supported browsers, because it runs as a Mac app beside the browser rather than inside it. Nothing gets installed in the browser, so the same sidebar, Spaces and keys follow you if you switch browsers again. It runs on macOS 14 or later.
That outside position is why it can fill the gaps the five browsers leave. Each of them copied the parts of Arc that fit inside its own window, while Little Arc, routing for outside links and a Ctrl+Tab that knows every browser all need something that runs across apps.
Here is what that looks like for someone keeping Safari for personal browsing and Chrome for work.
| Space | Linked to | Pins and saved links |
|---|---|---|
| Work | Chrome, Work profile | mail.google.com, calendar.google.com, linear.app, figma.com |
| Personal | Safari | youtube.com, reddit.com, amazon.com, netflix.com |
Switching Spaces swaps the pins and links and shows only that Space's open tabs. An Air Traffic Control rule keeps figma.com links in Chrome's Work profile, ⌃Tab jumps back to the last tab whichever browser it was in, and a Slack link opens in SupaView without leaving Slack.
A few limits are worth knowing. SupaSidebar's Spaces don't separate sign-ins by themselves, so link each Space to a browser profile for that. Live Tabs reads open tabs from most browsers but not Arc or Zen. And SupaView only takes links from the sidebar, the Command Panel and other apps, not links clicked inside a web page.
Keeping the browser you already have is the point for some people. One Arc user put it this way in an r/ArcBrowser thread on October 27, 2026. "Im going back to safari with supasidebar. Just don’t want another browser which will disappear." The setup for each habit, step by step, is in the Arc habits setup guide.
Which browser setup should you pick?
- If you want to stay in Safari, it has the most partial matches of the five, and vertical tabs arrive with macOS 27.3. Add SupaSidebar for Spaces, Little Arc and Ctrl+Tab, or see How to Add a Sidebar to Safari.
- If you want another Arc-style browser, Zen has Spaces, Glance and Space Routing, and still no Little Arc.
- If work makes you use Chrome or Edge, keep each account in its own profile and link one SupaSidebar Space to each.
- If you live on the keyboard, Firefox covers Ctrl+Tab by itself, and SupaSidebar adds Cmd+T and Ctrl+Tab to every browser.
- If you used Arc mostly as a tall tab list, any browser's vertical tabs are enough.
- If you are moving to Dia, plan to lose Little Arc, Peek and Air Traffic Control.
Conclusion
No browser has Arc's features as a set in November 2026. Across Chrome, Safari, Brave, Firefox and Edge, 1 of 45 habit checks is a full match, and Little Arc has no native match in any of them, Zen and Dia included. Safari comes closest with 7 partial matches, and Zen is the Arc-style browser that kept the most, with Spaces and a near-copy of Peek.
Safari users lose the least by staying put, especially once macOS 27.3 adds vertical tabs in December. Chrome and Edge users get vertical tabs and profiles but have to rebuild Spaces, Little Arc and Ctrl+Tab. Brave and Firefox users get the tall tab list, and Firefox adds the one native Ctrl+Tab match. People choosing between Zen and Dia should know that Zen kept Peek and Spaces while Dia kept neither.
Arc stops working on December 22, 2026, and personal data is deleted within 30 days after accounts are deactivated, per Arc's sunset key dates. Pick the browser you want, then add the habits it lacks. To get all nine back in the browser you already use, try SupaSidebar (free version available).
Why we recommend SupaSidebar
SupaSidebar is a macOS app that brings Arc's sidebar to every browser - one sidebar for tabs, bookmarks, files, and apps across 32+ browsers including Safari, Chrome, Firefox, Edge, Brave, Vivaldi, Dia, Helium and Orion. For Arc users, it brings back Spaces, pins, the Cmd+T command bar, Ctrl+Tab, Little Arc, Peek, Air Traffic Control and auto-archive in whichever of those browsers they keep, with no browser extension.
FAQ
What is Little Arc?
Little Arc was Arc Browser's small window for links opened from other apps. Clicking a link in Slack, Mail or another app opened it in a compact Arc window instead of the full browser, so you could read it and get back to work. Arc stops working on December 22, 2026, and no mainstream browser has a built-in replacement. SupaSidebar's SupaView opens links from other apps in a small floating window the same way.
Does Zen browser have Little Arc?
No. Zen's Glance opens a floating preview for links you click inside Zen, which matches Arc's Peek, but it doesn't open links that come from other apps. To get a Little Arc window next to Zen, SupaSidebar's SupaView opens links from Slack, Mail or Terminal in a small floating window once SupaSidebar is set as the default browser.
Does Dia have Little Arc?
No. The Browser Company's Arc sunset FAQ lists Little Arc among the Arc features Dia does not have, along with Peek, Air Traffic Control, Boosts and Easels. Dia also uses Profiles instead of Arc's Spaces.
Does Brave browser have Spaces like Arc?
Not yet. Brave has vertical tabs, tab groups and profiles, but its Workspaces feature is unfinished and ships turned off, per Brave's own issue tracker. To make Brave look like Arc with Spaces, SupaSidebar adds a sidebar with Spaces beside Brave, and each Space can link to a Brave profile.
Does Firefox have Spaces like Arc?
No. Firefox has had vertical tabs since Firefox 136 and tab groups since Firefox 138, and in November 2025 Mozilla described workspaces as an open question it was still asking users about. Zen, which is built on Firefox, does have Arc-style Spaces.
Is there an alternative to Arc's Peek?
Yes. Zen's Glance opens links from pinned tabs and Essentials in a floating preview, the closest match inside a browser, and Safari previews a link when you Force Click it on a trackpad. In any browser, SupaSidebar's SupaView opens a ⌘-clicked sidebar link in its own floating window.
What is Air Traffic Control in Arc Browser?
Air Traffic Control was Arc's set of rules that sent links to a chosen Space based on their domain, added in May 2023. No mainstream browser has a full copy. Safari and Edge can tie a site to a profile, and Zen added Space Routing in June 2026. SupaSidebar's Air Traffic Control routes links by URL to any browser or profile.
