It took some work, but I managed to install the app Signal without a physical smart phone. But there is a big drawback with this.

Here's what I decided to do: About Kubernetes Descision Kubernetes is just too complicated for me. I don't have any doubt I could learn it, but the thing I'm worried about is getting caught in the Kubernete internals for hours and days instead of writing code and doing actual development.

BigBlueButton would meet your requirements: open-source: Yes. Does not require to own a server or domain (by me): While you can self-host it, there are providers offering it for you.

Sockets on the local host are the most usual way of doing this sort of thing - the file option can hit problems unless: a) Each thread has its own file & b) all writes are flushed and event then you can hit buffering problems & race conditions.
