The 7 best web browsers in 2025
And there's plenty more to like about Vivaldi. Its unique tab management tool allows you to stack multiple tab rows on top of each other, so you can group certain websites to clear clutter and make more room on your main tab row. On the sidebar, you can similarly pin panels for quick access to anything, like your notes, reading list, messaging websites, and browsing history.

Brave Alternative - 8 Privacy-Focused and Reliable Options
Compared to Brave, Vivaldi lacks privacy features, but the huge extension support compensates for that. In my experience, both Brave and Vivaldi offer the same browsing speed, and the system impact was also equal.

If you just want a simple reader to subscribe to a few feeds and you don't need a mobile client or all the bells and whistles, this is a great choice. Vivaldi's RSS reader is free and built-in to the...

  • Firefox will have an option to disable all AI features
    The solution for the (as of yet) small group of people who cares about these things is very simple: community driven forks.

  • I tried 6 next-gen browsers - here's what I found
    Last, but not least in my journey to find the perfect browser for me is Vivaldi. This browser was developed back in 2015 by a former Opera co-founder and markets itself to primarily power users.
