I love using repl.it for creating node express server but I'm having the following problems:
At one point it cannot start, saying port 3000 is already in use and there is no way to kill it. What I do is duplicate the repl and go from there :/
My server goes down after some time so I want to ask if there's a good reliable host for my node server
For the first issue, just change the port number, then wait for a while (I would recommend refreshing the page, too) and then revert to the original port number.
For the second issue, use UptimeRobot: https://repl.it/talk/ask/Express-Server-Timeout/13054.
