What are the basic supported scenarios and capabilities of Code With Me?
The host can start a session to invite other participants (guests) and share project code with them. Session participants either follow each other or navigate the code independently. The session participants can edit code located on the host’s computer. The host can start a debugging session and share its state and actions.
What is the maximum number of participants that can join one session?
The Code With Me session can currently support up to 20 participants including the host. However, the active code editing is limited to 5 guests at a time.
How and what data is going through JetBrains' servers?
Your project/solution data is going through JetBrains' servers end-to-end encrypted. The end-to-end encryption is secure only when a host and a guest verify that the generated fingerprint matches on both ends. Otherwise, the end-to-end encryption is susceptible to MitM.
Local IP addresses, project name, and username are shared without encryption as they are used for letting JetBrains establish a session between a host and a guest. When initiating a new Code With Me session, the host communicates with JetBrains server over TLS1.2+.
Code With Me communicates through an open source distributed protocol created by JetBrains and uses TLS 1.3 for end-to-end encryption.
What project/solution data is accessed by JetBrains?
JetBrains accesses local IP addresses, project name, and username. JetBrains doesn't access information related to project contents such as sources, project files, config files, because this information is flowing through its servers end-to-end encrypted.
What data is collected during a live session?
JetBrains doesn't inspect or collect any data on the code that is shared during the Code With Me sessions because the information is flowing through the JetBrains servers end-to-end encrypted.
Are any files stored locally on the guest's machine?
No, the shared code resides on the host's machine and is not uploaded to or stored in the cloud or the guests’ computers.
Both the host and guests can collect and store locally log files that include detailed information about the session such as user names, remote addresses with which the connection was established, caret movements, typed symbols, invoked actions, parts of file contents, files opened, file paths, and so on.
What files are accessible by the guests? Are they restricted to a particular working directory?
There are no restrictions in accessing different parts of the host’s project, executing code, or working in the terminal tool window during an active session.
Does Code With Me support plugins?
Plugins that perform customization of the IDE are supported. The guest cannot download and enable any language or framework related plugins.
Is Code With Me compatible with other editors such as VSCode, Vim, Emacs, and so on?
No, but as a guest, you can customize your local environment and add a keymap of your choice by installing and enabling the needed plugin.
How can I download Code With Me?
The Code With Me plugin is available starting with the IntelliJ IDEA 2020.3 version, and you can install it like any other IntelliJ IDEA plugin.
What are the minimum/recommended system requirements for Code With Me?
The minimum and recommended requirements can be found here.
However, for guests only a lightweight client application is downloaded, so the requirements for disk space and computer resources are lower than for a host.
How do I use Code With Me behind proxy
If you work in a local network, you can bypass proxy restrictions by using a private on-premises server.
As an alternative, you can add the following urls to the allowed list:
What are the current limitations for working with Code With Me?
