Opera

Opera is a free web browser for Android, iOS, Linux, macOS, Windows, and the web, with extension support and cross-device sync. Tab Islands group related tabs for collapsing or expanding. Built-in tools include an ad blocker that can also block cryptocurrency-mining scripts, plus a free VPN with no data cap and three general locations. Opera AI can use open-tab context, generate images, summarize PDFs, and translate or summarize YouTube videos. ChatGPT and Gemini are available from the sidebar, and Opera says its AI tools do not require sign-up. The sidebar also offers WhatsApp, Slack, Discord, Messenger, and Telegram, while Music Player supports Apple Music, Spotify, YouTube Music, and Deezer. Users can set browsing data—including history, cookies, passwords, and autofill data—to clear on exit. Opera browser costs nothing. VPN Pro is separate: plans cost $4 per month billed $48 yearly, $5 per month billed $30 every six months, or $8 per month billed monthly.
