DuckDuckGo Browser vs Vivaldi

DuckDuckGo Browser is a browser for Android, iOS, macOS, and Windows, with a free plan and paid subscriptions. It blocks third-party trackers, including those from Facebook and Google, and most ads, including video and YouTube ads. It can block most cookie pop-ups and may opt users out automatically. Cross-device sync and a password manager are included, and a one-click control clears tabs, history, and browsing data. Email protection blocks hidden trackers in emails, while Duck.ai offers optional private chats with popular AI models. DuckDuckGo says those conversations are not used to train AI and that it does not track searches; its tracker list and exceptions are open source. Paid plans add VPN protection, advanced AI models, personal information removal, and identity restoration. Plus costs $9.99 a month or $99.99 a year. Pro costs $19.99 a month or $199.99 a year and adds Claude Opus 4.8, GPT-5.6 Sol, higher reasoning effort, and twice Plus’s Duck.ai usage limits. DuckDuckGo has been independent since its founding in 2008 and is based in Paoli, Pennsylvania.

Vivaldi is a free Chromium-based web browser for Android, iOS, Linux, macOS, and Windows. It combines tab organization with built-in browsing and productivity tools. Users can group tabs in two-level Tab Stacks, arrange them into Workspaces, or view pages side by side with Tab Tiling. Included tools are Mail, Calendar, a Feed Reader, Notes, Sync, and webpage translation. Vivaldi supports Chrome extensions, including in its Android browser. Privacy features include ad and tracker blocking, cookie-warning hiding, and private windows; the maker says Sync uses end-to-end encryption for synced browsing data. Its privacy policy says each installation sends a daily HTTPS message to Vivaldi’s Iceland servers with an installation ID, version, CPU architecture, screen resolution, and time since the previous message. Vivaldi says its Security Group reviews code and new technologies, handles vulnerability reports, and prepares fixes. The company is based in Oslo, Norway, and was founded in 2014.
