Although Flarum scales very well, it is not losing sight of shared hosting environments. The only requirement is composer/ssh; hosting providers usually offer these nowadays.

Flarum only released its first stable last year and so has some features missing, yet https://extiverse.com already lists over 500 extensions compatible with Flarum v1.3. Relying on much used technology allows for fairly easy adoption by developers to contribute.
