Pros
- Opera features a rebuilt, free, and unlimited browser AI that offers contextual responses based on your open tabs or "Tab Islands." It can analyze page content and even summarize YouTube videos .

- The sidebar is highly functional, offering quick access to popular messaging apps (WhatsApp, Instagram, X). It now also includes integrated Google services like Gmail and Google Calendar for improved productivity .
Cons
- Opera is a Chromium-based browser, which means it is part of the ecosystem dominated by Google's engine, potentially raising concerns about the future of browser diversity.
- While it has a long history, its market share is significantly smaller than competitors like Chrome, Edge, or Firefox, which may be a consideration for some users.
- The built-in free VPN is convenient, but like many free VPNs, it is often limited in server locations and speed compared to paid, standalone VPN services .
