I want to run a small Discord bot. How can I find an inexpensive and reliable server for this?

There are a lot of good services that solve your problem, but most of them are really expensive, and without a trial period. But there is one service that has been tested for years, and for which I have a list of promo codes that will allow you to familiarize yourself with it without cost, digitalocean promo code here is this site with promo codes. I'm sure it'll work for you
