'''Snap''!''''' (formerly Build Your Own Blocks) is a free block-based [[List of educational programming languages|educational]] graphical programming language and online community. Snap allows students to explore, create, and remix interactive animations, games, stories, and more, while learning about mathematical and computational ideas. While inspired by [[Scratch (programming language)|Scratch]], Snap''!'' has many advanced features. The Snap''!'' editor, and programs created in it, are [[web application]]s that run in the browser (like [[Scratch (programming language)|Scratch 3]]) without requiring [[Installation (computer programs)|installation]].{{#tag:ref|BYOB, Snap''!''{{'}}s predecessor, was a modification of Scratch and could export projects as [[Portable Executable|Windows executables]].|group=Note}} It is built on top of ''Morphic.js'',<ref name="morphic_js">{{cite web |last1=Mönig |first1=Jens |title=morphic.js |url=https://github.com/jmoenig/morphic.js/blob/master/morphic.txt |website=GitHub |accessdate=7 June 2023}}</ref> a [[Morphic (software)|Morphic]] GUI, written by Jens Mönig as 'middle layer' between Snap! itself and 'bare' JavaScript.

While the software itself has little restraints, it does have some limitations.

These include as follows:

* 10 [[megabyte]] file cap for uploading (Snap''!'' Cloud only)

* Users have to manually enable Javascript when loading a project that uses inline bits of JS, due to a hack a few years ago.
