What Is Arc Browser? Is It Safe to Disable at Startup?

What Is Arc Browser?

Arc Browser is a web browser made by The Browser Company. It is an alternative to browsers like Chrome, Edge and Safari, with its own interface and features for tabs, workspaces and web apps.

On Windows and macOS, Arc may appear in startup-related lists if it is set to reopen in the background, restore previous windows, handle links, or keep helper components available for notifications or faster launch. That is usually part of normal browser behavior, not a system requirement.

Is It Safe?

Yes, Arc Browser is generally safe if it was installed by you and the publisher shows as The Browser Company. A browser using CPU, memory, disk and network activity is normal because it renders websites, runs extensions and keeps tabs active.

If you are unsure whether the app is genuine, check the app location and signature. On Windows, open the file location from Task Manager or Kudu and inspect the file properties and digital signature. On macOS, check the app in Finder and confirm it is the expected Arc application from The Browser Company. If the name is Arc but the file is in an unusual folder, or the publisher does not match, investigate further.

Should I Disable It at Startup?

Usually, yes, if you do not want Arc running before you open it. Disabling it at startup is normally safe. The browser should still work normally when you launch it yourself.

Keep it enabled only if you want background behavior such as reopening quickly, handling links immediately, or receiving browser-related notifications as soon as you sign in. If you rarely use Arc, disabling startup is a reasonable cleanup step.

On macOS, also check whether Arc is set to reopen after login or allowed to run in the background. The exact setting name can vary, so look for login or background items related to Arc.

Why Is It Using High CPU or Memory?

The most common causes are many open tabs, heavy websites, streaming, web apps, extensions, or a stuck page. Browsers can also use a lot of memory to keep tabs responsive.

If Arc is using more resources than expected, close unused tabs, restart the browser, and test with extensions disabled if Arc supports that workflow on your setup. A single bad site can keep CPU usage high. On laptops, video calls and hardware-accelerated pages can also increase usage.

High usage by Arc is not fixed by deleting random system caches. If the browser itself feels broken, use its own reset, update or troubleshooting options first.

How to Disable or Remove It

If Arc appears in startup items, you can disable it without uninstalling the browser.

Windows: Disable the Arc entry in Task Manager > Startup apps, Settings > Apps > Startup, or in Kudu's Startup Manager if Arc is listed there.

macOS: Remove or disable Arc from Login Items, or turn off any Arc background/login item shown by Kudu.

If you want to remove Arc completely, uninstall it through normal app removal for your platform. If you plan to keep using it, disabling startup is usually enough.

Where Kudu Helps

Kudu can show whether Arc is actually set to start automatically and where that startup entry comes from. On Windows, it checks common startup locations such as Run keys, the Startup folder and Task Scheduler. On macOS, it checks Launch Agents.

If Arc is using a lot of CPU or memory, Kudu's Performance Monitor can show the process, its PID and current resource use so you can confirm whether the browser is the cause. If needed, you can end the process, then reopen Arc normally.

Kudu can also help you review browser-related cleanup safely. Its browser cleanup is designed to preserve cookies, history and passwords, while privacy traces are separate opt-in actions.
