Vivaldi (web browser)

Vivaldi () is a Norwegian-Icelandic freeware, cross-platform web browser with a built-in email client developed by Vivaldi Technologies. The company is employee-owned. Vivaldi was founded by Tatsuki Tomita and Jon Stephenson von Tetzchner, who was the co-founder and CEO of Opera Software. Vivaldi was initially released on 27 January 2015. Although it is accessible to general users, Vivaldi's design and feature-set primarily targets power users, in addition to former Opera users disgruntled by its transition from the Presto layout engine to a Chromium-based browser, which resulted in the loss of many of its distinctive features. Even though it is also Chromium-based, Vivaldi aims to revive the features of the Presto-based Opera with its own proprietary modifications. Vivaldi replaced Firefox as the default browser on the Cinnamon Community Edition of the Manjaro Linux distribution. As of March 2026, Vivaldi claims to have 4.0 million active users.
