Heroku is free if you don't need constant uptime (it shuts down your server when it's idle for a while and starts it back up when a request comes in). Then the cheapest paid tier is $7. It's also really pleasant because you deploy by just pushing your code; no SSHing or cron jobs. You do code an entire server process; you just don't manage it. So it's like halfway-serverless. The downside, other than being $7 instead of $5, is that that's only for a single process; you can't run multiple low-compute servers within that $7. The file system also gets wiped whenever you deploy, so it's not appropriate for a database.
