The browser, its built-in AI assistant and the unlimited free VPN cost nothing; Opera sells a separate VPN Pro add-on and earns mainly from search and partner deals.
Use tool ↗About Opera One
Opera One is Opera Software's flagship desktop browser for Windows, Mac, and Linux. It groups related tabs into color-coded 'Tab Islands,' runs a modular sidebar for messaging apps and Google services, supports split-screen browsing, and includes Aria, Opera's built-in AI chat and search assistant. The browser is free to use, with Opera's revenue coming from search and partner deals rather than user subscriptions. The company operates as Opera Norway, tracing back to Opera Software's 1995 founding, and also makes Opera GX and Opera Mini.

Pros & cons of Opera One
Opera One works as a full replacement browser for someone who wants an AI sidebar and tab management built in rather than bolted on through extensions. It's free, but its AI assistant and most differentiating features are Opera-specific, so switching back to another browser means leaving those behind.
Pros
- AI assistant (now branded Opera AI, formerly Aria) is built into the browser rather than a separate extension
- Tab Islands keep large numbers of open tabs organized by project, now with names and colours
- Free built-in VPN with no data cap, plus an ad blocker
- No subscription cost
Cons
- Some extensions built for Chrome behave inconsistently in Opera's engine
- Switching away means losing Tab Islands and the built-in Opera AI
- Smaller market share means fewer sites are tested specifically against it
Best for
- Users who keep dozens of tabs open and want built-in grouping
- People who want an AI chat sidebar without installing a separate extension
- Anyone wanting a free built-in VPN in the browser itself
Not for
- Teams standardized on Chrome-specific enterprise extensions
- Anyone who doesn't want an AI assistant integrated into daily browsing
