Last updated 4 June 2026
The simplest way to schedule a few accounts, and the cheapest entry if you only run one to three channels.
- From
- $5 per channel / mo
- Free plan
PostSyncer is a newer, AI-forward scheduler that publishes to eleven networks, bundles unlimited team members on every plan, and leans hard on built-in image and video generation. It's cheap and broad, though young and lighter on engagement and reporting.
- From
- $24 /mo
- Free plan
Bottom line
Buffer is the pick for solo creators, and it's the only one of the two with a free plan. PostSyncer fits creators and small teams wanting wide network coverage cheaply better, and it adds bulk upload that Buffer leaves out.
Buffer starts cheaper, $5 per channel / mo against $24 a month for PostSyncer. They bill on different units, so the real gap depends on how much you run. Buffer brings social inbox that PostSyncer skips, while PostSyncer has bulk upload Buffer doesn't.
