ZeroOmega

An open-source proxy switcher that manages and switches between your proxies.

Add to Chrome Open source · Chrome Web Store · Source on GitHub

Read this first: ZeroOmega is a proxy switcher, not a VPN. It supplies no proxy servers. It sends your browser traffic to proxies you set up. It is not a way to hide who you are by itself.

Why it's a strong pick

ZeroOmega is a fork of SwitchyOmega built for Manifest V3, Chrome's current extension format. That keeps a long-used proxy switcher working. It is open source under GPL-3.0-or-later, and its code is public on GitHub. The repo's latest release, v3.5.2, came in September 2026.

What it does

The README says it lets you "manage and switch between multiple proxies quickly and easily." You make profiles, each pointing at a proxy, and switch between them from the toolbar. You need proxy servers of your own, such as HTTP or SOCKS proxies.

Key features

  • Proxy profiles. Switch between several proxies.
  • PAC script generator. The repo includes a PAC module, omega-pac.
  • Settings sync. The release notes list WebDAV sync and automatic Gist creation.
  • DNS over SOCKS toggle. Added in v3.5.1, per the release notes.
  • Custom headers for rule fetching. Also listed in the release notes.
  • Shortcut. The README suggests Alt+Shift+O to open the popup.

Who it's for

ZeroOmega is for developers, testers and privacy-minded users who already have proxy servers and want to switch between them by site or profile. If you want a service that hides your connection with no setup, you want a VPN, and this is not one. See the VPN picks below.

What does a proxy switcher protect, and what does it not?

It changes where your browser sends traffic, to a proxy you chose. It does not encrypt your traffic, and we found no claim that it does. A proxy you do not trust can see the traffic that goes through it. It covers the browser only, not other apps.

What permissions does ZeroOmega ask for?

Its manifest asks for proxy, tabs, alarms, storage, unlimitedStorage, webRequest, webRequestAuthProvider and contextMenus. It also asks for access to all sites and needs Chrome 88 or newer. Controlling proxies needs the proxy permission. Read the install prompt before you add it.

Does ZeroOmega sync my settings anywhere?

Only if you turn it on. The release notes list sync through WebDAV and through GitHub Gist. Your profiles may hold proxy addresses and sign-in details, so think about where they go before you switch sync on. Leave sync off if you do not want those details stored with a third party, and review the choice in the extension's settings.

What about privacy?

The extension can see requests through its webRequest and all-sites permissions, which is how a proxy switcher does its job. We could not read the developer's privacy policy when we checked; read it before installing. Review the permissions on its Chrome Web Store listing, and decide whether you are comfortable with that level of access.

FAQ

Is ZeroOmega a VPN? No. It is a proxy switcher and supplies no proxies.

Is it open source? Yes, under GPL-3.0-or-later.

Is it the same as SwitchyOmega? The README says it is forked from SwitchyOmega and works with Manifest V3.

Good to know
