What it is
Vivaldi is a web browser built on Chromium by Vivaldi Technologies, a company started by former Opera developers. Its focus is customization: tabs can go on any side of the window and stack into groups, toolbars and keyboard shortcuts can be rearranged, and pages can be tiled side by side.
It also includes a built-in ad and tracker blocker, notes, and optional mail, calendar and feed reader apps. Vivaldi’s interface is not open source, though the Chromium code it builds on is.
Why it’s here
- Arrange it your way. Almost every part of the interface can be moved, hidden or remapped.
- More in one window. Mail, calendar and feeds sit alongside your tabs if you want them.
- Chrome-compatible. Chrome extensions install and Chrome-only sites work.
On CoreDesktop
CoreDesktop installs Vivaldi as a Flatpak from Flathub. Open it from the app grid. Helium is CoreDesktop’s default browser; to make Vivaldi the default instead, pick it in Settings › Apps › Default Apps.
The sandboxed AI agents can’t read Vivaldi’s profile, as they can’t read any Flatpak app’s data. update keeps Vivaldi current along with your other Flatpaks.
