This article or section documents an outdated version of Scratch (version 2.0). For this article in the current version, see Offline Editor. For this article in Scratch 1.4, see Scratch 1.4.

The Scratch 2.0 offline editor is a version of Scratch 2.0 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 teachers who wish for their students not to participate with the online community.

System Requirements

Main article: What are the system requirements for Scratch?

For Scratch to run properly, the following minimum system requirements are needed:[1]

  • Windows, Mac, or Linux operating system
  • Adobe AIR version 2.6+
  • Over 23 megabytes of free hard drive space


The Scratch offline editor can be downloaded from the Scratch site. There are two things that must be downloaded: Adobe AIR – a runtime system for desktop applications – and the editor itself.

Adobe AIR should be downloaded and installed first. While the Windows and Mac OS X links simply direct to Adobe's site, Adobe no longer supports Linux or Mac OS X 10.5 and earlier versions, so Scratch provides a link to the last supported version.

The offline editor should be installed next. It is provided as an .EXE file for Windows, a .DMG file for Mac, and a .AIR file for Mac OS X 10.5 and older operating systems.


The File menu of the offline editor

The offline editor has a few differences from the online editor. The File menu has different options, including a "Check for update" option and a "Quit" option which closes the Scratch program. Projects can be shared to the Scratch website, by accessing the File menu and clicking Share to the website. Projects are named by saving the project to one's computer (unlike the online editor, where text input above the stage is used). The offline editor still displays the name above the stage, though.

The tips menu also shows in full-screen mode in the offline editor. The top-right of the project editor, instead of displaying the login link or one's username, doesn't display anything.

The offline editor saves all projects in .sb2 format. There are no major differences between the offline editor and the online, apart from optimization for offline use. The Scratch offline editor has received many updates and can update itself.

Cloud variables are also not available in the offline editor, presumably because users cannot log in.


See also: Project Sharing

Uploading is now supported and is a similar process as Scratch 1.4's; however, it does not allow project instructions, notes, or tag inputs directly from the upload. There is a 50 MB project size limit, though the majority of projects do not reach that file size. However, users can bypass this limit by uploading an .sb2 file onto a project on the Scratch website. The projects are uploaded to the Scratch website, but they're not shared unless Scratchers share them by themselves.

Usage Survey

Usage Survey

In version 460, a new feature allowing usage of the offline editor to be automatically sent to the Scratch Team was added. It collects the language in use, block usage, and some action reports like uploading, saving, and loading. When the offline editor is first opened, a dialog is shown. If "No, thanks" is chosen, it doesn't send this telemetry. On Windows, the choice is stored in the following directory:

C:\Users\YOUR USERNAME\AppData\Roaming\\Local Store\#SharedObjects\Scratch.swf\scratchLocalData.sol

To change the setting, delete the file.
