Cerebro

Cerebro is a free desktop command center for people who want local and web search, quick file actions, and small utilities behind a keyboard shortcut. It is a strong fit for users moving between Linux, macOS, and Windows who value an extensible, open-source tool more than a narrowly focused launcher.

Overview

Cerebro searches the computer and the internet from one window. Results can open files in their default applications, reveal files in Finder, copy contact details, or show Google suggestions. Maps, translations, and file previews can appear in the launcher itself, reducing application switching for short lookups. The default window shortcut is Ctrl+Space, and Preferences lets users change it.

The application is built with Electron and released under the MIT license. The official download links carry version 0.11.0 labels for Windows, Mac, and Linux. Its open-source model also makes it a plausible base for users who want to inspect or extend the software rather than rely on a closed launcher.

Key features

Search, actions, and utilities

Core plugins provide web search, application search and launching, file navigation with previews, a calculator, and a smart converter. That combination turns Cerebro into a compact command hub: it can start software, locate files, perform a calculation, or convert a value without separate tools. The breadth suits keyboard-driven workflows, while someone who wants only an app finder may find the extra results and utilities unnecessary.

The search plugin supports Google, DuckDuckGo, Ecosia, Brave, MetaGer, and StartPage as named choices, but not all of those providers are implemented yet. That uneven coverage matters if a particular search engine is central to your workflow; Cerebro’s provider list should not be treated as uniform support.

Plugins and extensibility

A built-in plugin manager lets users add capabilities, and the API supports building and sharing plugins. This is Cerebro’s clearest differentiator for technically inclined users: the launcher can grow around their workflow instead of being limited to its core commands. It also means the experience depends on the plugins a user chooses and maintains.

Pricing

Cerebro — free. The plan is free and open source, with no paid plans listed. There are no seat charges or paid-tier trade-offs to weigh, making it suitable for individuals who want the full project without a subscription. Organizations should still assess whether community-built extensions meet their support and consistency needs.

Platforms

Cerebro runs on Linux, macOS, and Windows. The cross-platform release is useful for people who switch operating systems or need the same launcher concept across a mixed desktop fleet. It is a desktop Electron application, not a mobile-first tool.

Who it's for

Choose Cerebro if you want one keyboard-accessible window for app launching, local files, web queries, calculations, conversions, and occasional in-window maps or translations. It is especially well suited to open-source users and developers who want to create or share plugins. It is less suitable if you require every advertised search provider to work, or if a minimal app-only launcher is all you need.

Pros and cons

Pros: Free under the MIT license, with no paid plans; runs on Linux, macOS, and Windows; combines application launch, file navigation, web search, previews, calculator, and converter functions; supports custom plugins through an API; customizable Ctrl+Space shortcut.

Cons: Search-provider support is incomplete even though several engines are named; the broad plugin-driven scope may feel excessive for users seeking only application launching; Electron adds a cross-platform desktop layer rather than a platform-native launcher.

Alternatives

Browse App Launcher Software for a wider category view. Pick Raycast instead if you want a freemium launcher with extensions across macOS and Windows plus an API and features such as Clipboard History and Notes. Dropzone is the better choice on macOS when a customizable app, folder, and action grid or file shelf is the priority.

Launchy suits readers wanting a free, pay-what-you-want launcher across Android, Linux, macOS, and Windows. Choose Alfred for a macOS-focused launcher with free app launching and file search, or a paid single-user license for the current version. Ueli is another free cross-platform option with no paid plans or stated usage limits.

Winstep Nexus Dock is Windows-only and geared toward a dock, with a free personal plan and paid commercial licenses. bemenu is a free Linux/macOS choice built around a GPLv3 client and LGPLv3 library. Kunkun is a free cross-platform alternative whose application and community extension code can be examined on GitHub.

Verdict

Cerebro is a sensible recommendation for keyboard-oriented users who want a no-cost, open-source launcher that spans all three major desktop platforms and can be extended with plugins. Choose it for the combination of search, file actions, and utilities; look elsewhere if dependable support for every listed search engine or a simpler, more focused launcher matters more.
