- This article or section documents the current version of Scratch (version 3.0). For this article in Scratch 2.0, see Offline Editor (2.0). For this article in Scratch 1.4, see Scratch 1.4.
Scratch Desktop, otherwise known as the Scratch 3.0 offline editor, is a version of Scratch 3.0 that can be downloaded and installed on a computer, as opposed to being used in a web browser like the online editor. This is useful for those who wish to use Scratch without an internet connection or for class teachers who wish for their students not to participate with the online community. Scratchers also use it for creating a new version of their game without other users noticing.
- Main article: What are the system requirements for Scratch?
For Scratch to run properly, the following minimum system requirements are needed:
- Windows 10 or later or macOS 10.13 or later, though users have reported successfully running the editor on Windows 7
- Approximately 400 MB of free hard drive space
Downloading and Installation
Scratch Desktop can be downloaded from the Scratch website. An installer is provided which requires no interaction.
Scratch Desktop is slightly different from the online editor. Projects are named by saving the project to one's computer (unlike the online editor, where a text input above the stage is used). The tutorials also appear in Scratch Desktop. The top-right of the project editor, instead of displaying the login link or one's username, is empty.
Scratch Desktop saves all projects in .sb3 format. The Scratch offline editor will soon have the option to update frequently along with the online editor, so a notification will be pushed to the computer to warn of an update, and will allow the program to update without uninstalling.
Cloud variables are also not available in the offline editor, presumably because users cannot log in.
Backpack is not included in offline editor because users cannot log in.
- See also: Project Sharing
Uploading projects will soon be supported, and will be a similar process as to Scratch 1.4 and Scratch 2.0; however, it will not allow project instructions, notes, or tag inputs directly from the upload. There will be a 50 MB project size limit like Scratch 2.0, though the majority of projects do not reach that file size. However, users can bypass this limit by uploading an .sb3 file onto a project on the Scratch website. The projects are uploaded to the Scratch website, but they are not shared unless the user shares them themself.
