CodeTogether FAQ


See CodeTogether Security for more details

Is my code stored on CodeTogether’s servers?

No, our servers only relay data between members in a shared session. We do not store any relayed data. The code only ever permanently resides on the host and files being worked on are stored in temporary in-memory storage on the clients.

I want to be sure my code is seen only by those I invite to a session. Does CodeTogether use end-to-end encryption?

Yes, your code is end-to-end encrypted with a key known only to members of the session, and this key changes every session. If our server were to be somehow compromised, there would be no way to decrypt data to get to your source code. Your source cannot be read by, and is never stored on, CodeTogether’s servers.

Is the Audio/Video bridge encrypted?

A/V communications use encrypted WebRTC channels that are independent from CodeTogether session services. Due to limitations in how browsers currently support WebRTC, these communications are not end-to-end encrypted. In the unlikely event of these channels being compromised, as they are independent of the regular CodeTogether session, they can never expose access to the source code or your CodeTogether session in any way.

What data is actually relayed in a collaborative session?

Only the files being actively edited have their contents transmitted. For the rest of the workspace, only file names and paths are relayed so that the project/workspace structure is visible to all in the session. Requests/responses for language features like content assist, validation, navigation and code analysis are also transmitted. All this data is end-to-end encrypted.

What information does CodeTogether store?

We store IP address, IDE type, usernames and session duration for the purpose of license enforcement and server health/performance monitoring.

How do you ensure CodeTogether is free from vulnerabilities?

Each CodeTogether build is automatically scanned for vulnerabilities using Snyk, Trivy, and Dependency-check. We also perform rigorous code audits as part of every release to specifically ensure that there are no unexpected data transmissions and no leakage of unencrypted customer code. This includes an inspection of data packets transmitted by all members in a collaborative session.

Can I prevent participants from being able to edit in a session?

Yes, this feature was added in CodeTogether 3.1. When starting a session, the host is prompted to choose if participants will have editing privileges. CodeTogether Teams, introduced in 4.0, allows you to restrict access based on team members vs. non-team members.

Can I prevent the entire workspace/project from being shared in a session?

Yes, you can add exclusions to a .codetogether.ignore file in the root of each project. Please see this issue for more details. 

We would like to have a private instance of CodeTogether running behind our firewall. Do you support this?

Yes, we do have an on-premises version. Learn more

How can I configure my firewall to allow CodeTogether to function?

CodeTogether uses the following domains and ports, please ensure they are accessible:

Domain Ports Protocols 443 HTTPS
* 80 / 443 HTTPS / WebSockets
* 4443 TCP
* 10000 UDP
Is single sign-on (SSO) supported?

CodeTogether 4.0 introduced single sign-on (SSO) integration for on-premises installations. If the SSO provider supports the OpenID Connect protocol for sign on, on-premises installations can allow CodeTogether access to users only if they’ve been authorized by the provider. The OIDC protocol ensures CodeTogether works with providers like Okta, Azure AD, Microsoft AD FS and Auth0.


See our Getting Started Guide for more details

Can I join a session from an IDE?

Yes, this feature was introduced in CodeTogether 3.0. Hosts and guests can use Eclipse, IntelliJ, or VS Code. Everyone in a session can remain in their IDE, even if it is different than the IDE used by others in the session.

If I join from an IDE, will I get language support for languages my IDE doesn’t inherently support?

Yes, language capabilities such as content assist, validation, quick fixes, code analysis and navigation come from the host IDE, so as long as the host is capable, your IDE will be too. Conversely, your IDE’s language features will not be available for files shared by the host.

Why is the syntax highlighting for a shared file different from the native highlighting for that same language in my IDE?

In order to provide collaborative features, CodeTogether uses a custom editor for shared files instead of your IDE’s native editor. This is why the colors may not be exactly the same; we’re trying to minimize these differences.

Can multiple members edit at the same time?

Yes, multiple members in a session can edit code at the same time, even in the same file.

Is CodeTogether good for mob programming?

Yes! Participants can work solo, paired, as a mob, or any combination. Each session can include any number of dynamic groups. 

When I type, everyone in the session follows me. How do I code without disrupting others?

When you join a session, you’re added to a room in which there can be only one driver. To code without disrupting others, double-click Go to a personal room from the Coding Rooms node in the CodeTogether view. Alternatively, you can turn off the Shared Cursor toggle if you joined from a browser.

How do I rejoin a group?

In the browser, turn on the Shared Cursor toggle, or click any member you’d like to join in the CodeTogether view.

When I’m looking at code, my editor suddenly jumps to a different file/location. Why does this happen?

When you’re in a group and another member is actively editing, we allow you to break away to make quick edits or inspect other pieces of code. You remain in the group, and after you stop editing for a short time, we bring you back to the driver’s location. This allows you to make quick changes without disrupting the flow of a group coding session. However, if you’d like to code or browse independently, you can leave the group to code alone. 

Can participants see console output?

Yes, this feature was added in CodeTogether 3.1. Console output on the host is visible to all participants from the appropriate view: the Console view in Eclipse, the Run view in IntelliJ, or the Output view in VS Code or a browser.

Is there a shared terminal?

Yes, read-only terminal support is available if the host allows it. In addition, the host can give write access to participants with a Teams or On-Premises plan.

Can guests run unit tests and launches?

Yes, this support was added in CodeTogether 4.2. Access to this feature can be restricted with a Teams or On-Premises plan.

Is it possible for participants to access a web app running on the host?

Yes, support for shared servers was introduced in version 4.1 for users with a Teams or On-Premises plan.

I can join a session from a browser, but not from an IDE. Why?

This could happen if your project has a large number of files, see this issue for more details. As a workaround, consider using a .codetogether.ignore file to exclude files from the shared session.

Do you support audio or video calls?

Not at this time. Support for audio is on our longer term roadmap.

Where can I report a bug or request a feature?

On our GitHub issues page. Be sure to check for existing issues before filing a new one.

What IDEs do you support?
IDE To Host To Join
Eclipse Neon (4.6)+ Photon (4.8)+
IntelliJ-based IDEs 2019.1+ 2019.2+
VS Code 1.44+ 1.44+
In Rider, I don't see content assist, validation, or code-analysis. Is this IDE supported?

Due to Rider’s unique architecture, while shared sessions work, several language features do not. We are working on this.

Any plans to support X Code or Visual Studio?

Not at this time.

Can I join a session from a different IDE than the host's IDE?

Absolutely. For example, you can join a session started in Eclipse from IntelliJ.

What browsers can I use to join a session?

Most recent versions of modern browsers like Chrome, Firefox, Safari, Opera, etc. will work. If using Edge, we require version 44 or higher, including recent Chromium based builds.

Internet Explorer is not supported.

Note: Some key bindings cannot be overridden in a browser, consider joining from an IDE to access your complete key binding set.
