Cerebro is a free, open-source desktop launcher for Linux, macOS, and Windows. It searches a user’s machine and the internet, and can find and open files, reveal them in Finder, copy contact details, and show Google suggestions. Core plugins add web search, application search and launch, file navigation with previews, a calculator, and a smart converter. Cerebro can also display maps, translations, and files within its results without opening another application. It includes a plugin manager, and users can build and share plugins through its API. The default shortcut for showing the app window is Ctrl+Space, and users can change it in Preferences. The search plugin lists Google, DuckDuckGo, Ecosia, Brave, MetaGer, and StartPage as options, though the project notes that not all are implemented yet. Cerebro is developed in Electron, and its README identifies the license as MIT. The official site links to downloads labeled version 0.11.0 for Windows, Mac, and Linux. The listed plan costs nothing, with no paid plans listed.
