Adding websockets to an existing WSGI application with Muru, by handing requests to ASGI in the same worker, plus mounting ASGI beside WSGI and serving gRPC.

How a Muru development run serves HTTPS with a certificate your browser trusts, so HTTP/2, Secure cookies and URL schemes can be tested without a proxy in front.

How Muru imports a Python web application once and forks workers from it, checks the import is safe to fork, and how processes, threads and free-threading fit in.

The processes that make up Muru, the path a request takes through them, and why splitting things up this way is what makes releases and zero-downtime deploys possible.

Catching a slow request with a soft timeout, seeing where it is with debug stacks, profiling under load and attaching a debugger, all against a Muru development run.

Muru running for the first time, in development mode. Serving a WSGI application, what the terminal tells you, what happens when it fails, and why a reload is a release.
