Access Scratch on Your Computer
The easiest way to start using Scratch is to create an online account and start Scratching. To use Scratch without creating an account, you will have to download and install the offline version of Scratch.
Technically, you can use the Scratch website without an account, but you will have to save projects to your computer and then upload them each time you visit the Scratch website to continue working on them. With an account, you can save files online and share projects with other Scratch users.
Create online account
Go ahead and start up Scratch! If you already have a Scratch account, click the Sign In button in the top-right corner of the page. If you do not have an account, click the Join Scratch button and fill in the brief online form. If you are under 13 or do not have an email account, please ask an adult to help you create an account.
To run Scratch online, you need a relatively recent web browser (Chrome 35 or later, Firefox 31 or later, or Internet Explorer 8 or later) with Adobe Flash Player version 10.2 or later installed. Scratch 2 is designed to support screen sizes 1024 x 768 or larger.
Use Scratch offline
You can install the Scratch 2 Offline Editor to work on projects without requiring a Scratch user account. After Scratch 2 is installed you will not need an Internet connection to work on projects. This version will work on Mac, Windows, and some versions of Linux (32 bit). Download and install Adobe Air (required to run Scratch offline) and the Scratch 2 Offline Editor.
