IntelliJ IDEA is an Integrated Development Environment (IDE) for JVM languages designed to maximize developer productivity. It does the routine and repetitive tasks for you by providing clever code completion, static code analysis, and refactorings, and lets you focus on the bright side of software development, making it not only productive but also an enjoyable experience.

Why IntelliJ IDEA

The Most Advanced Editor

Write high-quality code faster with coding assistance features that search for possible errors and provide improvement suggestions as you type while seamlessly educating you on community best practices in coding, new language features, and more.

Deep Code Understanding

IntelliJ IDEA knows everything about your code and uses this knowledge to offer blazing fast navigation and an intelligent experience by providing relevant suggestions in every context.

Collaborative and Remote

Work on a project with your team in real time. Create shared sessions to review code, debug, and more. Move your projects to the remote machine to harness the full power of IntelliJ IDEA on any laptop and boost your productivity.

Out-Of-The-Box Experience

Enjoy an unbeatable toolset right from the first launch. Mission-critical tools and a wide variety of supported languages and frameworks are at your fingertips – no plugin hassle included.

System requirements

Remote Development is currently in beta. The system requirements will change over time, we will work to support more types of systems in the future. Systems that don’t meet the requirements may work with Remote Development, yet we will not be able to support issues that might arise along the way.

Depending on the size of your project, ensure that the system you connect to meets the following requirements:

Minimal requirements

• 4 vCPUs, either x86_64 or arm64 architecture. Also, higher clock frequency is preferred to higher core count.
• 8 GB RAM.
• At least 500MB of free disk space even if the IDE is already installed.
• A supported version of a common Linux distribution. Specifically, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, Ubuntu 22.10, CentOS, Debian, and RHEL are supported.
• Ensure the user, with which you are connecting, has one of these shells set: bash, dash, fish, csh, tcsh, ksh, zsh. On Ubuntu, ‘sh’ is aliased to dash.
• The following utilities must be available: tar, wget (or curl), dd, chmod, test, mkdir, echo, mv, uname, command, and gzip.
• The $HOME environment variable needs to be set correctly. The $HOME/.cache folder needs to be writable by the user with which you’re connecting.
• The IDE and the project should be on a local file system. Network block storage such as EBS is acceptable, a network file system such as NFS or SMB is not. Additionally, you need to have at least 8GB available.
• OpenSSH server, version 7.9p1 or later is recommended. Other SSH servers fully implementing RFC 4254 may work too, yet are not supported. SSH port forwarding must be enabled in server configuration.
• The server needs to have at least 50 Mbps downstream capacity from the internet.
• The connection between client and server should have at least 20 Mbps bandwidth, and no more than 200ms latency.
• Single tenancy within a server or container.

Recommendations

• For larger projects, add more CPUs and RAM. The load average indication in the IDE will tell you if an upgrade would be advisable.
• Enabling Swap is recommended. Even on cloud instances.
• Local SSD storage.

Not supported

• Single-board computers such as Raspberry Pi. To run your code on a Raspberry Pi, check out remote interpreters or remote debugging, and similar features.
