Canvas

Build a system. Break it on purpose.

Drag out a load balancer, app servers, a cache, a database - wire them together the way you would in a real design - then turn up the traffic and watch which piece gives out first, and why.

The canvas is a drag-and-drop workspace that needs real screen space to be usable, so it’s built for larger screens right now. Open this page on a laptop or desktop to build.
