Snap! (formerly BYOB) is a visual, drag-and-drop programming language. It is an extended reimplementation of Scratch (a project of the Lifelong Kindergarten Group at the MIT Media Lab) that allows you to Build Your Own Blocks. It also features first class lists, first class procedures, and continuations. These added capabilities make it suitable for a serious introduction to computer science for high school or college students.
Snap! runs in your browser. It is implemented using
Javascript, which is designed to limit the ability of browser-based software
to affect your computer, so it’s safe to run even other people’s projects,
even if you don’t trust our competence or good intentions.
Snap! is presented by the University of California at
Berkeley. It was developed by Jens Mönig at MioSoft Corporation, with
design input and documentation by Brian Harvey at Berkeley, and contributions
by students at Berkeley and elsewhere.

Privacy
For research purposes, this site uses Google Analytics to collect
aggregate information about, e.g., how often the site is used and what links are followed from it. We do not collect personally identifiable information, but if you have a Gmail account or have ever Googled yourself from your own computer, then, despite their assurances to the contrary, Google does collect such information. We recommend that you use AdBlock Plus, Ghostery, NoScript, and/or Privoxy to protect your browsing privacy. The first two are really easy to install and use; the last two take a bit more effort to whitelist sites you trust. (You might also consider the tracking-free DuckDuckGo search engine.)
