Choosing a default browser for AliveOS was not a decision we took lightly. Developers spend a significant portion of their day in the browser, and our goal was to ship something that respects both your productivity and your privacy. After careful evaluation, Vivaldi emerged as the clear choice.

Here is why.

Built-in Ad and Tracker Blocking

Vivaldi ships with a native ad blocker and tracker blocker enabled out of the box. No extensions needed, no configuration required. This means pages load faster, less bandwidth is consumed, and your browsing habits are not sold to the highest bidder. For a developer-focused distribution that values system efficiency, this aligns perfectly with our zero-bloat philosophy.

Chrome Extension Compatible

Vivaldi is built on Chromium and supports the full Chrome Web Store extension ecosystem. Every extension you rely on for development, security, or productivity works as expected. There is no walled garden and no compatibility gap to work around.

Built-in Mail Client

Vivaldi includes a full-featured mail client that supports multiple accounts, IMAP and POP3, search across folders, and a unified inbox. For developers who manage several email identities, this eliminates the need for a separate email application and keeps everything in one place.

Built-in Calendar and Feed Reader

Alongside mail, Vivaldi provides a private calendar for managing events and an algorithm-free feed reader for building a custom news feed based on your actual interests, not your behavioral profile.

Privacy by Design, Not by Feature

Vivaldi does not track you. There is no telemetry, no profiling, no data mining. Sync data is encrypted end-to-end, meaning even Vivaldi cannot read your bookmarks, passwords, or open tabs. The company is independent, European, and answerable only to its users, not to advertisers or investors.

Unmatched Customization

Vivaldi is the most customizable browser on the market. Developers can tailor every aspect of the interface to match their workflow:

  • Workspaces to separate projects, research, and personal browsing
  • Tab Stacking and Tab Tiling for side-by-side page views
  • Web Panels to keep chat apps, documentation, or dev tools in the sidebar
  • Quick Commands for keyboard-driven navigation
  • Custom keyboard shortcuts and mouse gestures for efficiency

Built-in Productivity Tools

Vivaldi ships with tools that replace entire categories of extensions:

  • Notes for jotting down ideas while browsing, synced across devices
  • Capture for full-page screenshots without third-party tools
  • Pop-out Video to watch tutorials or streams in a floating window while you code
  • Translate for one-click page translation, processed locally for privacy

Cross-Platform Sync

Vivaldi Sync works across desktop and mobile with end-to-end encryption. Your browsing data moves with you securely, whether you are on your AliveOS workstation, a laptop, or a phone.

At the end of the day, Vivaldi respects the same principles AliveOS was built on: give the user control, avoid bloat, prioritize privacy, and never compromise on the tools that matter. It is not the default because it is popular. It is the default because it is the right tool for the job.
