Blockly

Blockly is a client-side library for the programming language JavaScript for creating block-based visual programming languages (VPLs) and editors. A project of Google, it is free and open-source software released under the Apache License 2.0. It typically runs in a web browser, and visually resembles the language Scratch. It is also being implemented for the mobile operating systems Android and iOS, though not all of its browser-based features will be available on those platforms.
