Vivaldi is a web browser that is free to use, but that includes a customizable interface, tab tiling and web panels as organizational elements, email management features, and an integrated calendar, to make it a task and work organization solution. It is developed by Vivaldi Technologies headquartered in Oslo, Norway.
Vivaldi offers customization support in many subjects. If you are looking for something beyond what you already use, Vivaldi can be a good alternative for you. It may not be at a Chrome level in terms of performance, but if you are looking for an internet browser and tools that you can manage the details of, it is useful to have a look. In general, Vivaldi is an application that does everything adequately. It does not have a built-in VPN. But internally it offers mail, calendar, translation, and manageable tools (tab groups, etc).
It's a light and customizable browser, but it sometimes lacks stability. It happened to me that I lost a few hours of work due to random crashes on a 2018 MacBook.
Vivaldi Browser is great in terms of usability and customization, if you don't like something the way it is by default, there's a good chance that you can tweak to make it work for you
Since Vivaldi has a calendar built-in in the browser only so it is very efficient to add new events and edit already scheduled events, We can manage multiple calendars as per our needs without added complexity because it has a user-friendly user interface, events can be defined as tasks so that we can track progress on the projects.
