We are also changing how remote playback works for streaming personal media (that is, playback when not on the same local network as the server). The reality is that we need more resources to continue putting forth the best personal media experience, and as a result, we will no longer offer remote playback as a free feature. This—alongside the new Plex Pass pricing—will help provide those resources. This change will apply to the future release of our new Plex experience for mobile and other platforms.
Everything I see online says it’s free.
I’ve also used it recently and did not pay for it.
It’s against CloudFlare ToS to use CF tunnels for media streaming like this. You can risk it ig but I have important stuff like domain registrations on CloudFlare so I’m personally not willing to risk getting banned.
