I use it for my own small instance of Mastodon (https://s.o2l.ie). Looks like I have about 30GB of data in there... not a massive amount of bandwidth either (looks like around 200Mb over the last 7 days). But, it was easy to set up, and I think my last bill was around 23 cents for the month... AWS calculator is coming in at around $2 per month...
