Don't trust anybody who doesn't start with "it depends". For nothing in this world there is one perfect answer. Context means a lot. What have you coded? Why do you think you are done if it is not running anywhere (I would say you are 20% done if it runs on your laptop)? How many people need to use it to be viable (e.g. a diary service needs only one user who writes texts for himself, a shop needs at least make its hosting and transportation fees, a social network needs thousands of people before it can even start to be successful)?

Good general advice is this: The simplest solution is often the best, but in some cases that means taking your old desktop pc, install ubuntu, configure your router to publicly share http and https from that computer. In other cases it means using a toolset like Heroku.

Please don't be mad about this, but the way you phrase your question it is very very likely you have so little skill that you don't even know how little. Please consider to pay a freelancer to support you. He likely has more skill and has experienced more "this can never happen in real life" F-Ups than you, and therefore can handle a lot.
