8 Best Arc Browser Alternatives in 2026

The best Arc Browser alternative in 2026 depends on what you loved about Arc. Zen Browser is the closest match for its calm vertical interface. Vivaldi is best when you want more control. Horse Browser is for ADHD re-entry and for technical or research work that grows into hundreds or thousands of connected pages. Dia carries The Browser Company’s design taste into an AI-first browser.

Arc remains maintained and continues to receive Chromium and security updates. Its core product experience is no longer in active feature development.arc-status If Arc already fits, keep using it. Spaces, Split View, Boosts, and that beautiful sidebar are still excellent browser ideas.

This guide ranks eight Arc alternatives by the job each does best. If your choice is already down to two browsers, read the direct Horse Browser vs Arc Browser comparison.

Horse Browser made this list, so yes, the author has a horse in this race. Literally. There are no affiliate links and nobody paid for a position.

The ranking asks how well each browser answers one of the reasons people chose Arc:

No browser inherits all of Arc. The useful choice begins with the part you want to carry forward.

Zen Browser is the closest match for most people leaving Arc. It is a Firefox-based browser with vertical tabs, workspaces, compact mode, split view, and a visual sensibility that feels carefully considered.zen

That combination matters. Plenty of browsers can move tabs to the side. Zen understands that the sidebar is not merely a different parking place for tabs. It is the room.

Zen’s workspaces can be paired with Firefox container tabs, so different accounts stay apart inside the same browser. If you used Arc Spaces for work, personal life, and the side project that became a small constitutional crisis, this is familiar territory.

Choose Zen if: you miss Arc’s shape, visual calm, workspaces, and willingness to redesign browser furniture. Down to Zen versus Horse? Read the direct Horse Browser vs Zen Browser comparison.

Another browser may fit better if: every extension and website must behave exactly as it did in Chromium. Test the few things you cannot live without before moving the sofa in.

Vivaldi is magnificent if you enjoy deciding exactly how software should behave. Its built-in tab tools include vertical tabs, two-level Tab Stacks, Workspaces, saved sessions, tree-style views, and Tab Tiling for viewing pages together.vivaldi

Arc made strong choices for you. Vivaldi hands you the control panel and trusts you near the switches. Both are excellent approaches for different temperaments.

Vivaldi is especially good for people who used Arc as a serious work browser. You can keep separate Workspaces, group tabs inside them, and tile several pages when comparing documents, prices, or the seven hotels you have somehow developed personal opinions about.

Choose Vivaldi if: Arc made you want more browser control. Weighing it against Horse? Read the direct Horse Browser vs Vivaldi comparison.

Another browser may fit better if: the joy of Arc was having the design decisions made for you. Vivaldi can be beautifully calm after you choose how you want it to work.

We are big fans of tree-style tabs, and Arc made vertical navigation feel beautiful. Horse Browser makes Trails the browser’s complete, persistent navigation model: open pages, browsing history, and saved context all live in one tree.

That relationship is an ADHD accommodation. When an interruption happens, the Trail still shows how the task fits together. You can return without reconstructing the whole expedition from memory. Horse does not treat ADHD. It externalises the context a flat tab bar asks you to hold in your head.

The same mechanism becomes powerful when the work is simply enormous. A software engineer and investor who used Horse for a month organised equity research, web-app debugging, and library documentation in Trails, then moved his research into Horse. In a separate Creativerly review, designer Philipp Temmel described hundreds of research tabs in Vivaldi as mental load and found an even larger collection in Horse lighter and more manageable.

Choose Horse if: you have ADHD or autism, re-entry is hard, or your research keeps becoming a large web of connected pages. The full Horse Browser vs Arc Browser comparison shows the difference in detail.

Another browser may fit better if: Arc’s Boosts, Split View, themes, or Chrome extensions are essential. Horse is intentionally quiet, runs on macOS, Windows, and Linux, and costs $70 per year after a two-week trial.

SigmaOS is a macOS browser built around workspaces, keyboard navigation, split views, and page suspension. It uses WebKit, supports a selection of Chrome extensions, and has an AI assistant called Airis.sigma

The appeal is the same larger instinct behind Arc: a browser window can be a place where work is arranged, not merely a row of temporary pages. SigmaOS is particularly comfortable if you like moving around without reaching for the mouse every twelve seconds.

Choose SigmaOS if: you use a Mac, think in workspaces, and enjoy keyboard-first software.

Another browser may fit better if: you need Windows or Linux, or one specific Chrome extension is essential. Its official site lists macOS support and a selection of compatible extensions.

Dia is The Browser Company’s next browser. It can draw context from tabs and connected services, create reports and decks, organise related tabs, preserve split layouts, and separate work and personal browsing with Profiles.dia

If Arc Max was the beginning of what interested you, Dia is the obvious place to look. This is where the company is actively building its new ideas. The family resemblance is taste and ambition, while the central idea is AI working across the material in your browser.

Choose Dia if: you wanted Arc to keep moving toward AI-assisted work.

Another browser may fit better if: you mainly want Arc’s sidebar, Spaces, and visual playfulness to continue. Dia currently requires macOS 14 or later on an Apple silicon Mac.

Safari is a very good browser. It has Tab Groups, separate Profiles, extensions, strong integration with Apple’s password tools, and excellent continuity across Mac, iPhone, and iPad.safari

Safari does not try to recreate Arc. It offers a calm browser already connected to the rest of your Apple devices, which is a lovely answer in its own right.

Choose Safari if: you live inside Apple’s devices and want the browser to disappear into them.

Another browser may fit better if: Arc’s vertical interface, deep customisation, or the Chrome Web Store is the part you need most.

Brave is a Chromium browser with built-in blocking for ads and trackers. It also offers vertical tabs, a sidebar, tab groups, syncing, and broad compatibility with Chrome extensions.brave

Brave is an excellent landing place when you want familiar website and extension support with stronger privacy defaults. Arc asked how a browser should feel. Brave asks how much tracking should be allowed through the door. Both questions improved browsers.

Choose Brave if: privacy and Chromium compatibility matter more than recreating every part of Arc’s interface.

Another browser may fit better if: your main need is a spatial system for large projects. Brave’s useful tab tools support that job, while privacy remains its centre.

Google Chrome is the reliable default. It has excellent website compatibility, a huge extension library, Profiles for separating accounts, and almost no learning curve for existing users.chrome

Chrome is a strong choice when browser compatibility matters more than a new navigation model. Its extension library can add vertical tabs, tab managers, and many other Arc-adjacent ideas while preserving a familiar base.

Choose Chrome if: you want maximum familiarity and your existing extensions exactly where you left them.

Another browser may fit better if: the conventional tab bar was the reason you tried Arc in the first place.

Choose the browser that matches the part you need:

Install two, import nothing, and use each for an ordinary afternoon. A browser demo rewards novelty. Tuesday rewards fit.

Zen Browser is the closest Arc alternative for most people. It combines a vertical interface, workspaces, split view, and careful visual design. It is not an Arc clone, but it preserves more of Arc’s overall feeling than the other browsers on this list.

Arc is still available and continues to receive Chromium and security updates. The Browser Company says it is no longer actively developing Arc’s core product experience, while its new development effort goes into Dia.arc-status

Zen is a wonderful fit if you want an actively developed, Firefox-based browser with an Arc-like vertical interface. Arc remains a wonderful fit if its existing Spaces, Split View, Boosts, and particular design already serve you. “Better” becomes useful only after you finish the sentence.

Dia is The Browser Company’s next browser, but it is not Arc 2. Its central idea is AI working across tabs and connected services. Choose it for that direction; choose Arc, Zen, or another alternative for an Arc-style interface.

Both put navigation in a sidebar and both take tree-style browsing seriously. Arc organises tabs into Spaces. Horse replaces tabs with branching Trails that preserve the path from one page to the next. See Horse Browser vs Arc Browser for the direct comparison.

Zen is the strongest free choice for an Arc-like interface. Vivaldi is the stronger free choice for customisation. Safari, Brave, and Chrome are also available without a browser subscription. Horse is paid because it maintains a different navigation model for ADHD re-entry and connected research.
