You can set up paths that route to different local ports. As long as your apps don't need to live at the root path you can have as many as you like. And you can still have something on the root path as long as it doesn't need the subpath.

Here's `tailscale funnel status` on my machine:

    $ tailscale funnel status
    
    # Funnel on:
    #     - https://my-machine.tailXXXX.ts.net
    
    https://my-machine.tailXXXX.ts.net (Funnel on)
    |-- /            proxy http://localhost:3000
    |-- /foo         proxy http://localhost:3001
    |-- /bar         proxy http://localhost:3002
    |-- /baz         proxy http://localhost:4004
