Cerebro

Cerebro is a free, open-source desktop launcher that combines local and web search with file actions, application launching, and utility plugins. It suits keyboard-driven users who want one command window on Linux, macOS, or Windows, particularly those willing to extend a launcher through plugins. Its broad toolkit is useful, but search-provider support is not uniformly implemented.

Overview

Cerebro searches a computer and the internet from one interface. Results can open files in their default applications, reveal files in Finder, copy contact details, and show Google suggestions. Maps, translations, and file results can appear inside the launcher, reducing the need to open a separate application for short lookups.

The default shortcut is Ctrl+Space, and Preferences lets users change it. Cerebro is built with Electron and released as open source under the MIT license. Official downloads are labeled version 0.11.0 for Windows, Mac, and Linux. The project names Alexandr Subbotin as owner and founder, Gustavo Pereira as owner and core committer, and Christoph Flick as a core committer.

Key features

Search, launch, and file work

The core plugin set covers web search, application search and launching, file navigation with previews, a calculator, and a smart converter. That combination makes Cerebro a general command hub rather than a prompt limited to opening programs. File previews and quick calculations are practical for frequent short tasks; users who only need an app finder may not benefit from the additional scope.

The search plugin names Google, DuckDuckGo, Ecosia, Brave, MetaGer, and StartPage, while also indicating that some options are not implemented yet. That breadth is attractive for users who want provider choice, but it means a preferred engine should be confirmed before making Cerebro the primary web-search entry point.

Plugins and extensibility

A built-in plugin manager supports adding capabilities, and the API allows users to build and share their own plugins. This is the strongest reason to choose Cerebro over a narrowly defined launcher: teams or technically inclined individuals can shape the command set around their workflows. It also makes the experience more dependent on plugin availability and maintenance than a fixed feature list.

Pricing

Cerebro costs 0.00 USD on its Free plan. The plan is free and open source, with no paid plans listed, so there is no subscription tier, seat allowance, or paid upgrade to weigh. That makes it suitable for anyone who wants the full published product without a recurring charge, while users seeking commercial support or tier-specific service terms should look elsewhere.

Platforms

Cerebro is cross-platform, with official downloads for Linux, macOS, and Windows. A single launcher choice can therefore cover mixed desktop environments, although the Electron foundation may be less appealing to readers who prefer platform-native software.

Who it's for

Choose Cerebro if you want keyboard-first access to applications, files, web searches, calculations, conversions, and quick actions in one place. It is especially well suited to open-source users and developers who value an MIT-licensed project and the ability to create or share plugins. It is a weaker fit for someone seeking only a minimal app launcher, or for anyone who requires a specific search engine that is not yet implemented.

Pros and cons

Pros

• Broad command scope: app launching, file navigation, web search, calculator, and converter functions share one window.
• Useful file actions: opening files, Finder reveal, and previews reduce extra navigation for routine work.
• Extensible and open: the plugin manager, public API, and MIT license support customization and sharing.
• No price barrier: the complete published plan is free and open source across three desktop platforms.

Cons

• Uneven search coverage: several engines are named, but not all are implemented.
• Potentially more tool than needed: the broad plugin mix may be unnecessary for users wanting only application search.
• Electron-based desktop app: readers preferring native implementations may favor another launcher.

Verdict

Cerebro is a strong choice for open-source, keyboard-driven users who want local and web search, file actions, utilities, and plugin extensibility without paying. Choose it for breadth and cross-platform reach; look elsewhere if a minimal native launcher or guaranteed support for one particular search provider matters more.
