Release Date August 2018
Programming language HTML5 / JavaScript
« 2.0

Scratch 3.0 is an announced version of Scratch to succeed Scratch 2.0. It is a complete redesign and reimplementation of Scratch.

The public alpha release was released at https://preview.scratch.mit.edu in January 2018.[1] The final release date for the online version of Scratch 3.0 is set for an August 2018 release.[2] The offline version of Scratch 3.0 will come later. The name "Scratch 3.0" was first implied by Scratch Team member Andrew Sliwinski (thisandagain) in May 2016, following the trend.[3] It was later confirmed by the preview FAQ in January 2018.

Scratch 3.0 will be written in HTML5, which is a general term for the latest HTML, CSS, and Javascript web-based markup and programming languages. Scratch 3.0 will primarily use the WebGL, Web Workers, and Web Audio Javascript libraries.[4] Javascript is a widely supported language across all web browsers, and WebGL was picked for its speed and ability to perform operations like "touching color". Unlike Adobe Flash, Javascript works without requiring any plugins.
