Wavebox also stays browser-first, but its positioning is more explicitly about multi-client workflows. Its current feature pages highlight app-centric navigation, Spaces that sit side by side, cookie isolation at the Space level, Groups, Focus Mode, split-screen work, and a large app directory. It is trying to make a heavy browser day feel structured rather than chaotic.
That makes Wavebox a strong fit if your whole job already lives in a browser and you want more control without leaving that browser mental model. If you like managing many apps, tabs, and client accounts inside one powerful browser environment, Wavebox is the more browser-productivity-heavy option in this comparison.
