help with server

how do you make multiplayer game where you can join and make server becaus you cant have youre computer on all the time to run a server

microStudio can export the server for Node.js, so you can use a free provider such as Render or Vercel (requires you to use Next.js). Other people can also run the server by adding ?server to the project run URL. You can also try creating your own hosting and communication code with no server using something like Peer.js.
