A farewell to Arc browser

Arc is being shut down

The team behind Arc has decided to end support for its browser on December 22, 2026. The company says it will now focus its security work on Dia, a newer browser it built from the start to meet today's security rules. The team says the same people who made Arc also made Dia.

Key facts

• Arc ends on December 22, 2026.
• Passwords, bookmarks, extensions, and history move to Dia on their own.
• Spaces, Folders, and Tab Groups also move to Dia with their data kept intact.
• The company says Dia is now better than Arc in stability, speed, and security.
• Browser features that work in Arc are free in Dia. The AI tools are optional.

What is a browser?

A web browser is the app you use to visit websites, like Chrome or Safari. Companies keep updating browsers to fix security holes, which are weak spots that bad actors could use to attack users. Arc was one of several newer browsers that tried to offer a fresh design.

Why it matters

Arc users now have a deadline to switch. The company is betting that its new browser, Dia, is safer and easier to use. Users who want to keep their saved passwords and tabs organized can move their data over without starting again.

What to watch

• Whether Arc users switch to Dia before the December 22, 2026 deadline.
• How Dia's security and AI features change over time.
• Whether the team releases the bigger new projects it hinted at.
