Is there an inexpensive or free hosting for a socket server on Node?

Question

Node.js

Actually, subject. Slowly sawing the database for fencing tournaments and got to the module for recording the progress of battles. Accordingly, the idea is that there is a small SPA that implements the interface of the tournament secretary and the backend (Node.JS), which writes the details of the meeting to the database. The connection between them (as well as between the back and SPA of the tournament scoreboard) was thought to be done on web sockets so that the scoreboard could display the progress of the battle almost in real time. But those free hostings that I've watched so far all gravitate toward web functions, but here I would like a permanent connection for at least the entire fight (and for the scoreboard, for the entire tournament). There is no desire to pay big money for this, the project is purely a hobby (I fence myself), can you advise something? If there is also Muscle / Postgres, it will be generally good.

PS: As a last resort, you can rewrite this to the REST API, but then the scoreboard module will have to constantly pull back requests, and this somehow comes out ugly.

Answer 1

VDS is worth a penny.

Answer 2

rewrite the API in PHP and not have hosting problems

Answer 3

What's the problem with using heroku?
