POE Tool for crafting?

Is there a tool out there where we can create a skill tree and craft items that will give estimates for our dps, armor, es, whatever? I use poeplanner.com for all my theory crafting but I've always wondering if there is a tool that I can add items to my character for testing?

I'm pretty sure you can do so with this one:

I am on Linux though, so I can't test it.
