**As of Plexamp 4.8.0 a Plex Pass is no longer *required* to run Plexamp *unless* you are using Plexamp Headless**
However, Plex offers Premium Plexamp features that are not available on the free plan. Monthly and annual pricing options are available, but they also offer a Lifetime Plex Pass.
If you think you’ll use Plex and Plexamp for at least 3 years, it makes sense to go for the Lifetime Pass.
