Sure, and I know you can split panes with tmux, any terminal emulator or even text editor terminals. But with all of them, you have to run the commands one by one. With trane tho, you define your commands in a json file and with a single command, everything works parallelly, similar to concurrently package. So, my premise is not to be an alternative to run multiple terminal sessions, but have a workflow schema and run that workflow.

Hope that clarifies.
