Foreplay is where performance teams save, track and brief winning ads. Mostly picks up where the brief ends: Moss turns ideas into on-brand carousels and image ads, and posts them for you.
Foreplay is the deeper research tool. Mostly is the tool that makes the content. Teams with a real ad budget often want both.
Anything in Mostly that isn't fully live yet is labelled Beta, Rolling out or Coming soon.
Taken from each pricing page in November 2026. Prices change, so check before you buy.

A hire costs a salary. A stack of tools costs a bill per tool, and someone still has to run it all. Switch on what you pay for today and compare it with one Moss.
