Create a new project

On the Project creation page, fill out the form:

  • Set the project name
  • Select the environment you want to use in this project
  • Since environments are versioned, select the environment version from the dropdown
  • Optionally activate an add-on with the toggle button
  • Optionally add a thumbnail or description
  • Optionally add kernel environment variables using the + icon in the dedicated section
  • Save your project

Note that you can save changes to your project information in the same way: simply edit it and save.

  • Create a public snapshot

    Once your project is saved, a new section titled Public snapshot appears in the form. As the name suggests, this feature allows you to generate a public snapshot of your private project at a specific point in time.

    Before generating a snapshot, the placeholder displays: Last saved: N/A

    After a snapshot is created, it updates to show the timestamp, such as: Last saved: February 2, 2026, 4:45:50 PM

    The section includes three buttons:

    • Hard drive icon: Creates a new snapshot.
    • Trash icon: Deletes the existing snapshot.
    • Link icon: Generates a shareable link using the snapshot.

    The following video shows how to create a public snapshot.

  • Launch the project

The following video shows how to launch a saved project by clicking the rocket button.

You can also access it from the projects panel by clicking the folder icon in the left sidebar. To launch a project, simply click on its corresponding card.

Note that you can use different xeus-kernels depending on the language you are using in your project: xeus-python, xeus-cpp, xeus-r, and other ones.
