This page gives you a glimpse of Squeak without installing anything. It is using SqueakJS, a Virtual Machine for running Squeak on top of JavaScript. Besides running regular Squeak code, SqueakJS also lets you access JavaScript via the JSBridge.

It currently works best in Chrome, also works in FireFox and IE, but sometimes crashes in Safari. It is quite slow compared to native Squeak, because this is executing a Squeak Virtual Machine inside a JavaScript Virtual Machine.

Above you see a stripped-down version of Squeak 2.2, which was released in 1998. Modern Squeak versions are much more advanced, but more demanding, too.

Other Squeak images
