is there possible only to deploy binary version of web application based on django , no source code publish?
Thanks
No, there isn't a reliable to do this at the moment. Even compiled code like referenced in the answer above this one isn't 100% secure.
My advice: clean open code for your clients and a good relation with them is the only way to go. Keeping your code hidden can be good from a business point of view but from a client relation point of view it's a real show stopper. Advertise: "Our code is open!", which doesn't mean your clients can do anything they want with it.
