Elixir LiveView offers a nice way to interact with the browser. I’ve been playing rendering OpenAI Atari frames from their Python objects (using erlport), so it seems like a plausible option for interacting with axiom too. Note that sagemath.org already interacts with axiom, so maybe connecting through it serves like a bridge.
