Vivaldi
Norway
Highly customisable, privacy-respecting browser made in Oslo.

A browser from Oslo, made since 2014 by a team led by Jon von Tetzchner, one of the people who started Opera, back when Opera was the browser for power users. Vivaldi is the spiritual successor: built on Chromium, so Chrome extensions work, but with an interface you can bend in almost any direction.
What's built in
- Tab management, stacks, tiling (view several pages side by side), pinned tabs, a two-level tab bar
- Side panels for web pages, notes, downloads and more
- Mail, calendar and feed reader, a full IMAP email client and RSS reader inside the browser
- Notes with screenshots and attachments
- Ad and tracker blocker built in
- Deep theming, custom keyboard shortcuts, mouse gestures and command chains
Privacy
Vivaldi doesn't track or profile its users. The Chromium core is open source while parts of the interface are proprietary; the company is in Norway and runs its sync servers in Iceland.
Who it's for
People who want to configure their browser, the kind who miss old Opera, or who keep installing extensions to recreate features Vivaldi just ships. It can feel overwhelming at first; the payoff is a browser that works the way you want rather than the way a designer in Mountain View decided. Free, on desktop and Android (the iOS version is newer and more limited).
