What ubnt products require flash? airOS works fine for me without flash.

Unifi 3.x requires flash to manage devices on a map. It's the main screen you see when you log in.

Unifi 4.x is still beta and I'm not sure if it still requires flash (Though for Ubnt stable means beta, beta means alpha, alpha is unlikely to even run.)

Last I checked AirControl did too (managing many AirOS devices)
