Top 15 IntelliJ plugins to install
The Community version of IntelliJ includes access to nearly 4,000 plugins. You can search for new plugins on the official JetBrains plugin marketplace.
JetBrains comes with a number of bundled plugins, which you can browse on its GitHub repository. Plugins created by the community, however, make IntelliJ an even more powerful development platform.
To install an IntelliJ plugin, visit the Settings/Preferences dialog with using the shortcut CMD + , or CTRL + ,. Next, select Plugins in the menu. From here, you will be able to search the plugin marketplace and install any plugin that you need.
To get you started, we’ve compiled a list of some of the most useful IntelliJ plugins that any developer can use.
1. Rainbow Brackets (1.4M)
Rainbow Brackets adds rainbow brackets and rainbows parentheses to your code. Color coding your brackets make it easier to find paired brackets so that you don’t get lost in a sea of identical brackets.
2. .ignore (9.8M)
This plugin is designed to manage your .gitignore, .npmignore, .dockerignore, and other .ignore files.
With this plugin, you will get files syntax highlighting and custom .ignore file templates. You will also be able to quickly add any selected file or directory to your ignore rules from a convenient popup menu. If you don’t want to see ignored files in your Project View, .ignore includes an option to hide those files.
3. Native Terminal (48k)
JetBrains includes an integrated terminal, but sometimes you want to use the native terminal outside of the IDE. Native Terminal adds a terminal icon to the IDE toolbar and context menu that will open project directories in your favorite terminal. Native Terminal supports native terminals across Windows, Linux, and macOS, as well as PowerShell, ConEmu, Cmder, WSL, GitBash, RXVT, and iTerm.
4. Scratch (108k)
Need somewhere to quickly jot down your thoughts or code snippets? Scratch lets you open temporary IntelliJ text editor tabs where you can write down code or ideas that you want to reference later but don’t need to save forever. You can keep a running list of scratches that are easily accessible with Scratch’s list popup, which can be opened with ALT+C, ALT +S.
5. GitToolBox (680k)
JetBrains includes version control tools by default, but GitToolBox can extend those features to make your Git management more powerful.
GitToolBox adds a status display, auto fetch, inline blame annotation, commit dialog completion, behind notifications, and more.
6. GitLink (55k)
GitLink provides a shortcut to open any file or commit in GitHub, Bitbucket, GitLab, Gitea, Gogs or GitBlit using your default browser.
7. BashSupport (12.6M)
BashSupport adds Bash language support to IntelliJ. BashSupport supports run configurations, syntax highlighting, rename refactoring, documentation lookup, inspections, and more. IntelliJ is bundling a new Shell plugin, but BashSupport is more robust and feature-rich.
8. Codota (540k)
Codota provides line completion suggestions so that you can write code faster and more efficiently. Trained on millions of open source Java projects, Codota offers full-line autocomplete and in-line code examples.
Codota supports Java and Kotlin. Codota is free to use, but they offer a paid option that lets you use your own data to customize Codota’s recommendation engine.
9. Atom Material Icons (180k)
Atom Material Icons will replace JetBrains’ icons with Atom File Icons and Material Design Icons. If you want to change up how your IDE looks, swapping in new icons can make a dramatic difference.
10. CamelCase (230k)
Quickly switch between CamelCase, camelCase, snakecase, and SNAKECASE. CamelCase is great for writing API documentation or refactoring lots of code.
11. Markdown Navigator (4M)
Markdown Navigator makes writing Markdown files easier so that you can write documentation faster. You can insert links and images quickly, convert HTML to Markdown, refactor referencing elements, automatically format your writing, and more.
Markdown Navigator includes many great basic features for free, but you might also consider paying for a yearly license to get access to even more features ($16 USD/year).
You should note that JetBrains offers its own Markdown plugin, although the reviews are mixed.
12. Docker (2.2M)
The Docker plugin, created by the JetBrains team, lets you download and build Docker images, create and start Docker containers, and carry out other related tasks. If you work with Docker frequently, this plugin can simplify many of your most common workflows.
13. EditorConfig (1M)
EditorConfig is a great tool for development teams who want to maintain consistent coding styles across different editors and IDEs. With EditorConfig, you can define project properties such as indent style, indent size, tab width, end of line characters, and trimming whitespace. The EditorConfig plugin for JetBrains will quietly enforce your EditorConfig settings in your code.
All settings are stored in an .editorconfig file. You can store this file in a git repo and make it accessible to your entire team.
14. Code Glance (930k)
Code Glance adds a code minimap into the editor pane to help you navigate around your code. It works well with both light and dark themes.
15. Code Time (11.7k)
Code Time is our automatic time-tracking extension for IntelliJ. The in-editor dashboard shows you daily and weekly reports of your programming activity right in your code editor. In the IntelliJ status bar, our Code Time extension displays real time metrics—like hours coded per day and daily average—so you can see how you’re tracking.
Visiting the web app gives you access to even more interesting data visualizations. See your 90-day coding heatmap, code start times, work-life balance, top projects, and more.
10 IntelliJ settings to customize
To change your settings, visit the Settings/Preferences dialog with using the shortcut CMD + , or CTRL + ,. Next, select the menu item on the left that best matches what type of setting you’d like to edit: Appearance and Behavior; Keymap; Editor; Version Control; Build, Execution and Deployment; Language & Frameworks; or Tools.

1. Customize actions, menus, and toolbars
Under Appearance and Behavior > Menus and Toolbars, you can change what items appear in menus throughout the IDE. You can change your IDE to only have your most frequently used options in the menus to reduce clutter. You can also change the icons on your toolbar.
You can also make a quick list. A quick list lets you compile a few of your favorite actions, map them to a particular hotkey, and open a popup menu with your preselected options.
2. Customize code style
IntelliJ can help you follow code guidelines when writing code. Under Editor > Code Style, you have access to style options for each language that you use. You can set tab size, indent size, continuation index, and more to ensure that your code follows your team’s guidelines.
3. Change fonts
Under Editor > Font, you can select new fonts for your IDE. You can also edit font size, line spacing, and font ligatures.
