Wired magazine likes the Vivaldi web browser, calling it a tool for power users just like "500-pound squats are to power lifters". Led by a founder of the Opera browser, Vivaldi Technologies' browser eschews the pared-down base browser plus extensions model for one in which personalization rules. "You can truly make Vivaldi yours" is the company's mantra.

The new Vivaldi 1.3 adds new options for personalization, most notably custom themes to allow customization of every UI element, protection for WebRTC IP leakage to improve privacy and additional mouse gestures, bringing to 90 the number of customizable browser actions. Platform-specific improvements for Linux users in this release include improved right-click tab hibernation for conserving system resources and better support for proprietary media in HTML5.
