The proprietary browser Vivaldi 8.3 has been released, developed on the Chromium engine by former developers of the Opera Presto engine. Vivaldi builds are available for Linux, Windows, macOS, Android, and iOS. The changes made to the Chromium codebase are distributed under an open license. The browser's interface is written in JavaScript using the React library, Node.js platform, Browserify, and various pre-built NPM modules. The implementation of the interface is available in the source code, but under a proprietary license.
The project aims to create a customizable and functional browser that maintains user data privacy. Key features include a tracker and ad blocker, note managers, history and bookmarks, private browsing mode, synchronization secured with end-to-end encryption, tab grouping mode, a sidebar, a configurator with many settings, horizontal tab display mode, as well as an integrated email client, RSS reader, and calendar.
The new version features a completely redesigned ad and tracker blocker, allowing users to customize their own blocking levels. By default, four levels are available: 'Disabled' (turns off the blocker), 'Weak' (blocks most tracking and some ads), 'Medium' (blocks almost all tracking and ads, some websites may break), and 'Strong' (blocks almost all tracking and ads, websites may frequently break). The browser now also remembers individual blocking level settings for each site.

Among other improvements:
- Auto-hide of the tab panel on cursor hover (when positioned at the side).
- Pinned tabs shown as icons (when the tab panel is positioned at the side).

- Simultaneous opening of multiple links from the clipboard.
- Copying tracker-free links.
- Support for the Chromium group API (now allows the use of extensions to manage tabs).
- Improved performance of the reading mode.
- In the Android version, the ability to copy tracker-free links, open links in an external app, open a link in a selected group, and support for Proton has been implemented. VPN.
- In the iOS version, the setting for the position of the new tab has been added, along with the ability to copy tracker-free links.
