I just have a question. Would it be possible to run python and nodejs in the same project but with a different instance for both of them? like python is running separately from nodejs
Basically, in order to run two different web servers, you need to use two different ports.
Glitch only opens port 3000 for the project container, but you might be able to get different internal ports running via reverse proxy. (No actual example found though, so it can be harder than it sounds.)
