Is it possible to run some code from another IDE for Hydra running locally in a computer?

Same in subject, but for the love of suffering is it possible to run code in Emacs for example, and have Hydra running as a local instance in my computer. Obviously, I want changes to happen as in an instant like typing/editing within the Hydra window. I am reaching Hydra through localhost:8000 so does that mean I have to make the app serve the file I am editing or is there another easy way to communicate.
