Default browser
Set Vivaldi as the macOS default browser so external links stop opening in whatever macOS guessed first.
The browser setup is simple on purpose. No Edge, no Chrome-first posture, and no wandering search defaults. Vivaldi is the main browser and DuckDuckGo is the default search engine inside it.
The browsers-ai Homebrew slice installs Vivaldi, DuckDuckGo, VS Code, Codex, Claude, and Antigravity together.
These are the browser checks worth doing before other app state starts piling on.
Set Vivaldi as the macOS default browser so external links stop opening in whatever macOS guessed first.
Set DuckDuckGo as the default search engine inside Vivaldi, not just in the companion browser app.
Sign into the main Vivaldi profile and let sync pull tabs, workspaces, bookmarks, and extensions back in.
Skip the browsers and launchers that are no longer part of the daily stack.
A tight browser checklist is better than a long browser essay.
