I've created a browser based token maker using the Html5 Canvas and the KineticJS library. It's in the early stages, but it runs in recent Chrome and Firefox browsers. IE is not supported, and Safari and others have not been tested.
It works much like TokenTool. Drag images from your PC into drop areas for the overlay image and the base image. Drag the images around the edit canvas, and use the mouse scroll to zoom in and out of the base image. Right click the clip result image to save.
The app is better explained on my blog at serpentineowl.com, look for Html5 Token Maker. The app is located at html5tools.serpentineowl.com/Html5TokenMaker.htm. The github address is github.com/SerpentineOwl/Html5TokenMaker.
I hope people find this useful.
