In-Depth Overview
What is Arc Browser?
Arc Browser was a freeware web browser developed by The Browser Company, founded by Josh Miller and Harsh Agrawal. Launched as a Chromium-based browser for macOS and later Windows, Arc introduced a radical reimagining of the browser interface with a permanent vertical sidebar replacing traditional horizontal tabs, 'Spaces' for organizing browsing contexts, and built-in productivity tools like 'Easels' for collaborative notes and 'Peek' for quick previews. Arc gained a devoted following among productivity enthusiasts and creative professionals for its innovative approach to managing digital workspaces. However, in May 2025, The Browser Company announced they were sunsetting active development on Arc to focus on their new AI-native browser, Dia. As of 2026, Arc remains available and receives security updates, but no new features are being developed. The Browser Company was acquired by Atlassian in 2025.
What is Zen Browser?
Zen Browser is a free, open-source web browser built on Mozilla Firefox that emerged in 2024 as a privacy-focused alternative to Chromium-based browsers. Designed with a beautiful vertical sidebar and sophisticated tab management, Zen captures the organizational philosophy that made Arc popular while adding robust privacy protections and active open-source development. Zen Browser includes features like Workspaces for context switching, Zen Mods for deep customization, split view for multitasking, and built-in tracker blocking. Being Firefox-based, it uses the Gecko engine rather than Chromium, offering a genuine alternative in a browser landscape increasingly dominated by Blink. In 2026, Zen Browser is under active development with regular releases, an engaged community of contributors, and a clear roadmap. It's completely free with no premium tiers, making it an accessible choice for privacy-conscious users who want Arc-like organization without the sunset concerns.
Detailed Feature Comparison
Active Development
CriticalArc Browser is officially discontinued as of May 2025. The Browser Company ceased all feature development, shifting focus to their new Dia browser. Arc receives only security updates and critical bug fixes. No new features, improvements, or platform expansions are planned.
Zen Browser is under active open-source development with regular releases throughout 2026. The project has an engaged community, frequent updates, and a public roadmap. New features like enhanced Zen Mods, improved workspace management, and platform expansion are actively being developed.
Verdict: Zen Browser wins decisively. Active development is essential for browser security, compatibility, and feature evolution. Arc's discontinued status makes it unsuitable for new adoption.
Privacy & Security
CriticalArc, being Chromium-based, inherits Google's tracking infrastructure. While it includes some privacy features, it lacks comprehensive tracker blocking by default. As a proprietary browser from a venture-backed company (now owned by Atlassian), data handling practices are less transparent. With development ceased, future security enhancements are uncertain.
Zen Browser is built on Firefox's privacy-respecting foundation with enhanced protections. It includes built-in tracker and ad blocking, no telemetry by default, and open-source transparency allowing code audit. The browser does not collect user data and allows users to use their own Firefox Sync servers.
Verdict: Zen Browser wins on privacy through its open-source nature, Firefox heritage, built-in blocking, and lack of data collection. Arc's proprietary status and Chromium base make it inherently less private.
Tab Management
HighArc's vertical sidebar with 'Spaces' for context organization was revolutionary. Features like pinned tabs, auto-archiving of unused tabs, and the 'Library' for saved content provided excellent workflow management. However, with development stopped, these features will not improve or adapt to new web standards.
Zen Browser offers a comparable vertical sidebar experience with Workspaces, vertical tabs, and container tabs for account isolation. Zen Mods allow deep UI customization. Split view enables side-by-side browsing. The implementation is actively refined based on user feedback.
Verdict: Both browsers excel at tab management with similar philosophies, but Zen Browser wins due to ongoing refinement and community-driven improvements. Arc's feature set is frozen in time.
Extension Ecosystem
HighAs a Chromium browser, Arc had access to the entire Chrome Web Store, offering thousands of extensions for every conceivable need. This massive ecosystem is one of Arc's remaining advantages for users with specific extension requirements.
Zen Browser uses Firefox's extension ecosystem, which is smaller than Chrome's but still comprehensive. Most major extensions are available. Firefox's WebExtensions API provides good compatibility, though some Chrome-specific extensions may not work.
Verdict: Arc wins on raw extension availability due to Chromium/Chrome Web Store compatibility. However, Zen Browser's Firefox ecosystem covers most user needs adequately.
Performance (Apple Silicon)
HighArc runs well on Apple Silicon M3/M4 Macs through Chromium's native ARM support. However, it is resource-intensive due to its Chromium base and feature-rich nature. Performance will not improve as optimization efforts have ceased.
Zen Browser, built on Firefox's Gecko engine, is highly optimized for modern hardware. It offers excellent performance on Apple Silicon with efficient memory usage. Firefox's continuous performance improvements benefit Zen directly.
Verdict: Zen Browser wins on efficiency and ongoing optimization. While both run well on Apple Silicon, Zen's active development ensures it will continue to improve performance on new hardware.
Customization
MediumArc offered customization through themes, Spaces configuration, and Easel creation. However, deeper UI customization was limited, and with development ended, no new customization options will arrive.
Zen Browser's 'Zen Mods' system allows extensive UI customization through community-created modifications. Users can change the sidebar behavior, tab appearance, and interface elements. Being open-source, advanced users can modify anything.
Verdict: Zen Browser wins through Zen Mods and open-source flexibility, offering deeper customization than Arc ever provided.
UI/UX Design
MediumArc's design was its standout feature—a beautiful, minimal interface with a permanent sidebar, clean typography, and thoughtful animations. The 'calm' browsing experience with decluttered toolbars set a new standard for browser aesthetics.
Zen Browser captures much of Arc's aesthetic appeal with its vertical sidebar, clean interface, and focus on content over chrome. While slightly different in execution, it offers a similarly modern, distraction-free experience that Arc users will find familiar.
Verdict: It's a tie. Both browsers offer exceptional, modern UI design. Arc may have a slight edge in polish due to its venture-backed design team, but Zen's active development means its UI continues to improve.
Cross-Platform Support
MediumArc is available on macOS and Windows. Linux was never officially released and will not be developed. iOS support exists but is limited compared to desktop. With development ceased, platform expansion is impossible.
Zen Browser is available for macOS, Linux, and Windows (with the Windows version having reached beta status in 2025). As an open-source project, community ports and platform expansion are ongoing. Firefox's mobile foundation could enable future mobile versions.
Verdict: Zen Browser wins through broader platform support and the potential for continued expansion. Arc's platform availability is frozen.

Who Should Choose Which?
1Former Arc User Seeking Migration Path
Zen Browser is the natural successor to Arc. Its vertical sidebar, Workspaces, and organizational philosophy mirror what made Arc special, but with the crucial difference of active development. Zen Browser has become the go-to recommendation for Arc refugees in 2026.
2User Dependent on Chrome-Specific Extensions
If you require specific Chrome extensions with no Firefox equivalent (rare but possible), Arc remains functional despite its discontinued status. However, consider this a temporary solution while seeking alternatives, as Arc's security support will eventually end.
3Privacy-Conscious Power User
Zen Browser's open-source nature, Firefox foundation, built-in tracker blocking, and lack of data collection make it ideal for privacy-conscious users. The vertical tab organization is a bonus for power users managing many tabs.
4Open Source Advocate
Zen Browser is fully open-source, allowing code audit, community contributions, and self-building. This aligns perfectly with open-source principles, while Arc was always proprietary commercial software.
Migration Guide
From_arc → Zen Browser
1. Export your Arc bookmarks via Arc's export feature or manually from the Library. 2. Download and install Zen Browser from zen-browser.app for your platform. 3. Import bookmarks into Zen via the standard Firefox import process. 4. Set up Workspaces in Zen to replicate your Arc Spaces—create contexts for Work, Personal, Projects, etc. 5. Install Zen Mods to customize the sidebar appearance to match your preferences. 6. Explore Firefox extensions to replace any Arc-specific features you used. 7. Enable Firefox Sync if you want cross-device bookmark access. 8. Allow 1-2 weeks to adjust to Firefox's slightly different shortcut keys and behaviors.
From_zen Browser → Arc
Not recommended. Arc is discontinued software with no future. If you must switch from Zen to a Chromium browser, consider actively maintained alternatives like Brave, Vivaldi, or Edge rather than deprecated Arc.
Final Verdict
zen-browser
Winner
Runner-up
In 2026, this comparison is fundamentally about choosing between a discontinued legacy product and an actively developed modern browser. Arc Browser, despite its innovative history and beautiful design, has been officially sunset by The Browser Company. While it remains functional for existing users, it has no future and will eventually become a liability. Zen Browser, by contrast, has emerged as the heir to Arc's organizational philosophy—offering vertical tabs, workspaces, and a sidebar-centric experience—but with the crucial advantages of active open-source development, privacy-first architecture, complete free access, and a vibrant community. For any user considering these browsers in 2026, Zen Browser is not just the better choice; it's the only rational choice for a browser intended for daily use.
Bottom Line: Avoid Arc Browser in 2026—it is discontinued software. Choose Zen Browser for an actively developed, privacy-focused, free alternative that captures what made Arc special while offering a real future.
