I would like to recommend cheap hosting, which is ideal for Flarum - it offers access to SSH and Composer (and even more). It offers all versions of PHP (7.0, 7.2, 7.3). WAF protection (against attacks on the web application layer) is also available.
The servers are located in Poland (ATMAN, Warsaw).
I'm their customer for already over 6 years. Nothing to complain about:

Edit: Seems like my ref got removed. So if you're willing to support me, hit me up via PM and ask for my reflink 🙂 (I hope that's allowed?).
