Buffer is a calm, reliable queue for posts you've already made. Mostly makes the post first: Moss designs a carousel in your brand, then publishes it to TikTok and Instagram on your schedule.
Pick Buffer if your posts are already made and you need lots of networks. Pick Mostly if the hard part is making good carousels every week.
Anything in Mostly that isn't fully live yet is labelled Beta, Rolling out or Coming soon.

Ask for a week of carousels, approve the ones you like and drop them into your posting slots.
Yes. Plenty of people make carousels in Mostly and keep Buffer for networks we don't post to yet, like Pinterest or Bluesky. You can download any carousel and upload it anywhere.
No. Starter includes 3 connected accounts and Pro includes 6 for a flat monthly price. Buffer's paid plans are priced per channel.
TikTok and Instagram carousels today. X, LinkedIn, Facebook and YouTube are built and rolling out channel by channel. Buffer supports more networks right now.
Not yet. Post analytics are coming soon, and they'll feed back into what Moss makes next. If reporting is your main need today, Buffer is ahead.
Paste your website. Moss learns your brand and hands you a carousel worth posting.
