I had a look at the server code. Is the idea that you will just vertically scale up the server to handle the load, or is there a mechanism for scaling out horizontally?

Every other service can be scaled horizontally today. However, the Rust services are very efficient at processing traffic, and a single node can handle significant usage.

Shameless plug, but you might like https://plane.dev for this.
