Sources: buffer.com and postiz.com, 6 September 2026. Prices change — check both before deciding.

Pick Buffer if…

  • A real free-forever plan with 3 channels — seenpaid has no free tier at all and requires a card for its trial.
  • Per-channel pricing that is genuinely cheaper than seenpaid if you only run one or two channels.
  • MCP access on every plan including Free, which seenpaid cannot beat on price.

Pick Postiz if…

  • Open source under AGPL-3.0 with 35.5k GitHub stars, and fully self-hostable — you can run it on your own servers with no vendor lock-in. seenpaid’s revenue engine is closed.
  • More platforms than seenpaid: 30+ against 23, including several seenpaid does not support.
  • API access on every tier, where seenpaid gates some capability by plan.

A third option

Neither one can tell you which post made money

Buffer and Postiz both report reach and engagement, and neither connects to a payment processor — so if a post produced a sale, nothing in either tool will tell you. seenpaid schedules to 23 platforms like they do, then connects to your Stripe read-only and attributes each payment to the exact post that drove it. It ships a hosted MCP server with 50 tools so an AI agent can read those numbers too.

Worth saying plainly: if you do not sell anything, revenue attribution is worth nothing to you and one of the two above is the better answer.
