Arc Browser Status 2026: DISCONTINUED, Live, Atlassian Pivot

Arc Browser is not shut down, but it is effectively finished as a product. As of May 2026, Arc still downloads, installs, and runs on Mac and Windows. It receives Chromium security patches — macOS reached v1.146.0 on May 6, 2026. What it does not receive: new features, a roadmap, or active development from any team. The Browser Company stopped building Arc in May 2025 and pivoted to Dia, an AI-first browser. Atlassian completed its $610M acquisition of The Browser Company on October 21, 2025.

Key takeaways

• Arc is alive but frozen: downloadable and running in May 2026, security patches only, no new features and no announced sunset date.
• Atlassian’s focus is Dia, not Arc — the acquisition announcement mentions Arc once, in passing.
• Most Arc workflows port to Chrome: workspaces, command bar, peek previews, and session snapshots are all replicable without switching browsers.

The Short Answer: Arc’s Status in May 2026

Arc still works. You can download it today at arc.net. The latest macOS version is v1.146.0 (May 6, 2026); Windows is at v1.106.0 (May 14, 2026). Both updates are Chromium security patches, not feature releases.

What has stopped: active development, new features, and any meaningful product investment. The Browser Company announced maintenance mode in May 2025. Atlassian acquired the company four months later. Every engineer on the Arc team is now building Dia. Arc’s future depends entirely on whether Atlassian continues to fund the infrastructure — something they have neither committed to nor announced discontinuing.

The honest summary: Arc is safe to keep using today. It is not safe to plan around long-term.

The Timeline: How Arc Got Here

The arc of Arc (forgive it) is a familiar story in consumer software. The product built a devoted community. The company ran out of runway to justify continued investment at the original ambition level. Rather than kill it, they moved to maintenance mode while pivoting to a new product. Atlassian then bought the team for the team — specifically for the people who built Dia, and for Dia’s enterprise potential. Arc came along with the deal.

What Still Works in Arc Today

As of May 2026, the core Arc experience is intact:

The browser itself: tabs, browsing, rendering, extensions. Arc is Chromium-based, so it tracks Chromium’s security patches and supports the full Chrome extension ecosystem. An Arc user loses nothing in terms of extensions.

Spaces: Arc’s named workspaces still exist and still function. Switching between Spaces switches tab context as it always has. No new improvements are coming to Spaces, but the existing behavior works.

Command Bar: Cmd+T still opens Arc’s command bar. Tab search, history search, and action commands all function normally.

Little Arc: the mini floating browser window still works. This is the feature with no Chrome equivalent, and it continues to function for Arc users.

Sync: Arc’s cross-device sync remains operational as of May 2026. No shutdown of backend sync infrastructure has been announced. Atlassian has made no public commitment to maintaining Arc’s sync servers indefinitely. If backend services close at some future date, sync breaks without warning.

Boosts: custom CSS/JS site modifications still function.

What Doesn’t Work (or Is at Risk)

New features. There are none. Whatever Arc was in May 2025 is what Arc is today and will be for the foreseeable future.

Bug fixes. Security patches come through Chromium. Browser-specific bugs (things the Arc team would have fixed in the product itself) are not being addressed.

Community. Arc’s development community has largely disbanded. Third-party tooling around Arc has stalled. Arcify (v5.0.0 on CWS as of early 2026) replicates some Arc-style tab behavior in Chrome, but Arc’s broader developer ecosystem is effectively frozen.

Long-term infrastructure. Atlassian has not committed to maintaining Arc’s sync and account infrastructure beyond the immediate term. This is the most significant hidden risk for Arc power users who depend on cross-device sync. There is no announced shutdown date, and no announced commitment.

The Bigger Picture: Atlassian’s Plans for Arc

Atlassian’s acquisition announcement is unambiguous about its intent: build Dia, not continue Arc.

CEO Mike Cannon-Brookes described the vision: “Our vision is to make Dia the browser” optimized for SaaS-heavy knowledge work, with AI assistance woven into the browsing experience. The announcement mentions Arc once, identifying The Browser Company as “the team behind the incredible Dia and Arc browsers.” No Arc roadmap, no Arc investment commitment, no statement about Arc’s future at all.

Atlassian is a $50B+ enterprise software company (Jira, Confluence, Trello). The $610M acquisition was not a browser play. It was a talent acquisition to build an enterprise AI browser. Arc served its purpose as the product that proved the team could ship a differentiated browser. That chapter is closed.

This does not mean Arc will be killed imminently. Atlassian has no incentive to generate negative press by shutting down a browser that still has users. But the probability of meaningful Arc investment under Atlassian is effectively zero.

Dia: The Replacement That Isn’t a Replacement

Dia is available to download as of May 2026, on macOS 14+ with Apple Silicon only. It is a fundamentally different product from Arc: not a version 2, not a spiritual successor in any practical sense.

Where Arc was built for power users who wanted a highly customizable, workflow-focused browser, Dia is built for enterprise teams who want AI assistance across their SaaS tools. Dia integrates AI that can “read” your tabs and help you work across multiple apps. It is priced for knowledge workers ($20/month Pro tier reported for advanced AI features) and positioned against enterprise software, not consumer browsers.

Arc users who have tested Dia generally reach the same conclusion: these are different tools for different jobs. If you loved Arc for Spaces and the Command Bar, Dia does not replace them. If you want an AI co-pilot for Jira and Google Docs, Dia is built for you.

For Mac users with Apple Silicon who want to try Dia, it is available at diabrowser.com. Windows availability has been mentioned by Atlassian but has no committed release date as of May 2026.

If You’re Switching: Arc Features in Chrome

For users who want to leave Arc for a stable, actively developed platform, Chrome is the most common destination. The extension ecosystem is the main reason: Chrome extensions don’t work in Firefox-based browsers like Zen, which otherwise closely mirrors Arc’s design philosophy.

The feature gap between Arc and stock Chrome is real. Chrome 146’s native vertical tabs cover the structural change, but Spaces, the Command Bar, peek previews, and session history have no built-in Chrome equivalents.

For the full setup walkthrough — including how to configure workspaces, keyboard shortcuts, and peek previews — the Arc features in Chrome guide covers each one in detail. For Spaces specifically: Arc Spaces in Chrome.

Other Chromium alternatives. Vivaldi and Brave both offer vertical tabs and some workspace functionality without requiring extensions. Vivaldi in particular has a feature depth that Arc users often appreciate. These are active products under active development, a meaningful distinction from Arc’s current state.

Should You Wait for Dia?

Only if you’re on a Mac with Apple Silicon and want AI-assisted enterprise browsing. Dia is a real product with active development and a functioning public release as of May 2026.

If what you want is the Arc workflow — Spaces, Command Bar, fast tab management — Dia does not deliver it. The product is built around a different use case. Waiting for Dia to become “Arc but better” is waiting for something that isn’t coming.

If you’re on Windows, Dia has no release date. Chrome with extensions is the practical path today.

Where things stand in May 2026: Arc works, receives security patches, and has no announced shutdown date. The team that built it is at Atlassian building Dia. There is no realistic scenario where Arc gets new features. Use it while it runs, but migrate before you depend on it. Cross-device sync is the highest-risk dependency if Atlassian eventually shuts down Arc’s backend infrastructure.
