Two separate Vivaldi browsers on one Mac
Can you run two separate Vivaldi browsers on a Mac?
Vivaldi's profiles keep accounts apart, for free, in windows of one Vivaldi. Parallex adds a second Vivaldi as an instance of its own: started with a data folder of its own, opened on its own, its windows outlined in its color, with the links you choose sent to it.
Keep a second Vivaldi beside your own as a separate instance: its own sign-ins, cookies, history, extensions and Vivaldi settings, opened from Parallex, the menu bar or a shortcut, its windows outlined in its color.
How
- Install Parallex (below). Your Vivaldi isn't changed.
- Choose New Instance and pick Vivaldi. Name it for what it's for, like “Vivaldi Work”, and give it a color.
- Open it and sign in with the other account. Both run at once, each in its own windows, outlined in the instance's color.
Or without Parallex: every way to run an app twice on a Mac, compared.
What you get with Vivaldi
- Its own data folder: Parallex starts Vivaldi with a data folder of its own, so its sign-ins, cookies, history and extensions are separate from your Vivaldi's.
- Window outlines in its color, and its name in the menu bar, so you can tell the two apart at a glance.
- Opened on its own: from Parallex, the menu bar, the ⌃⌥Space switcher or a keyboard shortcut of its own.
- Links to the right browser: send links from other apps to the instance, with rules per site.
- Own identity, when you want it: a copy of Vivaldi with its own Dock icon, notifications and macOS permissions, which Parallex keeps up to date. The lab tries this copy every night too.
Tested every night
Parallex's compatibility lab makes a fresh instance of Vivaldi 8.2.4133.83 (the app itself, opened with a profile folder of its own, as New Instance makes it) every night on a clean Mac and opens it. On October 4, 2026, on macOS 26.6.2, it ran, and nothing reached the original's data. Its instances have run clean on all 2 nights since October 3. Made as its own copy instead (Own identity), it ran clean too. See every app's latest result.
Good to know
- The instance is Vivaldi itself, so it shares Vivaldi's Dock icon unless you turn on Own identity; its windows are outlined in its color instead.
Questions
Vivaldi has profiles and Workspaces. Why this?
Workspaces group tabs inside one window, with the same sign-ins. Profiles separate sign-ins inside one Vivaldi. An instance is a separate Vivaldi with its own data folder, opened on its own, with links you choose sent to it.
Get Parallex
Free to try, for macOS 14 and later. In Terminal:
curl -fsSL https://parallex.mandip.dev/install | shOr download the disk image, or with Homebrew: brew install --cask mandipadk/parallex/parallex. Then choose New Instance, pick Vivaldi, and give it a name.
Already have Parallex?
This opens New Instance with Vivaldi picked; you name it and choose its color.
