Opera One (currently early-access developer version) is a completely redesigned browser, planned to replace the flagship Opera Browser for Windows, macOS, and Linux later this year. Based on the principles of Modular Design, Opera One transforms browser interaction, delivering a liquid navigation experience that’s more intuitive.
With its release, Opera One becomes the first major Chromium-based browser utilizing a multithreaded compositor in its user interface. Opera One also introduces Tab Islands, a new, more intuitive way of interacting with tabs.
Opera One’s look is completely reimagined based on Modular Design. In this early-access developer version, this is most noticeable in the sidebar and tabs modules. As features are added or tabs are opened, elements in the respective module adjust automatically to make room. This user-friendly design declutters the interface and keeps browsing smooth and focused.
Opera is known for its innovative and useful features, but the variety of use cases leaves the browser busy with idle shortcuts. Opera One changes that with its modular interface, a dynamic space that deemphasizes unused components to make room for new ones. In the sidebar, elements are dynamically adjusted as others are added, making space for more cutting-edge AI integrations as they become available.
And as extensions become more and more relevant with new generative AI features, Opera One groups them in a collapsable module in the address bar, simplifying the interface while retaining quick access.
This portable version comes bundled with uOrigin ad-blocker and some settings set towards privacy.
