Buffer vs Postiz
Two schedulers, compared on the things that actually differ. Every figure below was read off Buffer’s and Postiz’s own pages on 6 September 2026 — not from a press release and not from memory.
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.
Questions

Buffer: Free plan; Essentials and Team are priced per channel ($5 and $10 per channel per month, shown alongside yearly billing). Postiz: From $29/mo (Standard, 5 channels) to $99/mo (Ultimate, 100 channels). API on all tiers. Both were read off their own pricing pages on 6 September 2026.
Do Buffer or Postiz show revenue per post?
Buffer: No — Buffer’s own guidance is to use UTM codes. Postiz: No. Neither connects a payment processor to individual posts, which is the gap seenpaid fills.
