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.
Blockly uses visual blocks that help simplify programming, and can generate code in JavaScript, Lua, Dart, Python, or PHP.
