Thebe is configurable by default in JupyterBook, but as of this time, the JB implementation seems to support only using the MyBinder backend.

But Thebe can also work with JupyterLite, which connects to an in-browser Pyodide kernel. See demo.

Pro

• Removes any external service dependencies (JupyterHub, etc.)
• Allows anyone to run the notebooks instantly, not just current Python Camp students.

Con

• Performance may suffer, depending on the user's computer
• Not necessarily a useful introduction to real-world Python environments
• May require some (a lot?) of overhead to get the Pyodide backend to work with JupyterBook in a seamless fashion.
