Vivaldi is built on top of Chromium (Chrome), so it shares many of its benefits. It is known for its extensive list of features and customisations, while still being privacy-friendly. One criticism is that their built-in ad block is subpar, so an alternative extension should be used. Their ecosystem consists of a Mail Client and a VPN (provided by Proton). Recommended for power users looking to make the most of their browser with additional apps connected directly.
