The Scratch 2.0 Offline Editor is a version of the Scratch 2.0 program that can be downloaded to a computer, as opposed to the online Flash 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.
- Main article: What are the system requirements for Scratch?
For Scratch to run properly, the following minimum system requirements are needed:
- Windows, Mac, or Linux (32 bit) operating system
- Adobe Air version 2.6+ (included in download)
- over 23 megabytes of free hard drive space
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 OS X versions 10.5 or lower, so Scratch provides a link to the last supported version.
The Scratch Offline Editor should be installed next. It is supplied as an EXE file for Windows, a DMG file for Mac or a .air file for Linux.
When downloading the Scratch 2.0 offline editor, 903 bytes will be used in total.
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 will 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.

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.
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\USERNAME OF YOUR COMUPUTER\AppData\Roaming\edu.media.mit.Scratch2Editor\Local Store\#SharedObjects\Scratch.swf\scratchLocalData.sol
If the setting needs to be changed, the entire file will have to be deleted.[problematic]
