Vivaldi 8.0 launches with tab stacking, built-in code editor

Vivaldi 8.0 is live, introducing tab stacking, full UI layout customization, and a built-in code editor and debugger [Vivaldi Blog]. The release targets power users and developers who demand fine-grained control over their browsing environment.

Tab stacking lets users group tabs vertically or horizontally, reducing clutter and improving navigation. Users can resize stacked tabs and switch between tiling modes on the fly. The UI customization suite now allows placement of toolbars, side panels, and tab bars anywhere on screen, with support for custom CSS injection for deeper styling.

Developer tools now include an in-browser code editor with syntax highlighting and autocomplete, paired with a JavaScript debugger that supports breakpoints and variable inspection [Vivaldi Blog]. These tools integrate directly with the browser’s inspector, eliminating the need for external editors during light development or debugging sessions.

Performance gains include faster page load times on mid-tier hardware and reduced memory usage during extended multi-tab sessions. The update is available on Windows, macOS, and Linux.

Vivaldi’s focus on user control contrasts with Chrome and Firefox, both of which have limited tab grouping and minimal layout flexibility. While Chrome dominates developer usage, Vivaldi’s niche appeal lies in its refusal to standardize the browsing experience.
