Can you run your own reCaptcha service, in your own web app?

Is the backend used by reCaptcha open source? Is it a simple web app that can be deployed in a given container?

Thanks, LES

Solution

Running reCaptcha on your own server would be very cumbersome, as it requires a constant supply of image data (scanned books) to work. Also it would kind of beat a part of the purpose, that is digitizing books for the common good. Besides, I don't think it's even available.
