Cerebro

Cerebro is a free, open-source desktop launcher for people who want local and web search alongside quick actions in one keyboard-driven window. It suits users on Linux, macOS, or Windows who value extensibility; its broad toolkit is less compelling if all you need is a simple app finder.

Overview

Cerebro brings machine and internet searches together with actions such as opening files, revealing them in Finder, copying contact details, and viewing Google suggestions. It can also show maps, translations, and file previews in the launcher, helping keep some routine lookups and file tasks in one place rather than switching applications.

The default shortcut is Ctrl+Space, and you can change it in Preferences. Cerebro is built with Electron and released under the MIT license. Its download links are labeled version 0.11.0 for Windows, Mac, and Linux.

Key features

Search, actions, and utilities

Core plugins cover web search, application search and launch, file navigation with previews, a calculator, and a smart converter. That combination makes Cerebro a useful general-purpose command window, not just an app launcher. It is a stronger fit for people who want several everyday tools at hand than for anyone who wants a narrowly focused way to open applications.

The search plugin names Google, DuckDuckGo, Ecosia, Brave, MetaGer, and StartPage, but not all of those options are implemented. That caveat narrows the appeal for users choosing a launcher primarily for a particular search provider. Google suggestions are also an available action.

Plugins and customization

A plugin manager is built in, and users can create and share plugins through Cerebro’s API. This gives technically inclined users room to extend the launcher beyond its core tools. The trade-off is that its scope depends in part on plugins, so users seeking a fixed, tightly defined feature set may prefer a simpler launcher.

Pricing

Cerebro costs nothing. The free plan is open source, and no paid plans are offered. There are no published seat or usage caps to weigh against the price; for users who want an extensible launcher without a subscription, the free, MIT-licensed model is a clear advantage.

Platforms

Cerebro provides downloads for Linux, Mac, and Windows, making it a practical option for people who use different desktop operating systems. Its platform support is limited to desktop in the published download set, so it is not the choice for someone seeking a mobile launcher.

Who it's for

Choose Cerebro if you want one keyboard-accessible desktop window for local and web search, file actions, previews, and utilities—and especially if you want the option to add plugins. It is less suitable if you need every named search engine to work, want a mobile version, or only need a basic app-opening prompt.

Pros and cons

• Pro: Search, file navigation, launch, calculator, and converter plugins put several common tasks in one launcher.
• Pro: Plugin management and an API let users build and share additions.
• Pro: Free and open-source availability across Linux, Mac, and Windows avoids a paid-plan decision.
• Con: Some search providers named by the plugin are not implemented, limiting provider choice in practice.
• Con: The described download set is desktop-only, excluding users looking for a mobile app.

• Alfred offers free app launching and file searching, with a $34, paid once Single License for one user and two of their own Macs; it is a fit if you use macOS and want that defined license option.
• bemenu is free and supports Linux and macOS; consider it if you want an option limited to those platforms.
• PortableApps.com Platform is a free, open-source platform under GPL with some MIT and CC components; consider it if that licensing model is a priority.

• Appetizer is a free, open-source option for Windows, with API and self-hosted platforms also listed.
• dmenu is a free Linux option under the MIT/X Consortium License; consider it if Linux is your only target platform.

Verdict

Cerebro is a good choice for desktop users who want a free, open-source launcher that combines search, file actions, and utilities and can grow through plugins. Its main reason to look elsewhere is the uneven search-provider support; users who need a specific provider or a mobile platform should choose an alternative aligned with that need.
