Buffer vs Postiz
Short answer: pick Buffer if you want free — 3 channels on its free plan with MCP included, and paid plans from $6 per channel a month. Pick Postiz if you run more than a few accounts or want to self-host: $29 a month covers 5 channels and $49 covers 30, it is open source under AGPL-3.0, and it supports 30+ platforms against Buffer’s 12. Both include MCP on every plan; neither connects to your payments.
Two schedulers, compared on the things that actually differ. Every figure below was read off Buffer’s and Postiz’s own pages on 24 September 2026 — not from a press release and not from memory.

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 to three channels.
- MCP access on every plan including Free, since 27 May 2026, which seenpaid cannot beat on price.
Pick Postiz if…
- Open source under AGPL-3.0 with over 36,000 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 21, including several seenpaid does not support.
- Unlimited posts, a public API, webhooks, AI video and YouTube clipping on every plan, and team seats from $39.
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 21 platforms like they do, then reads your Stripe 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.

Do Buffer or Postiz show revenue per post?
Buffer: No — nothing on its pricing or MCP pages connects a payment processor; it offers a free UTM generator for tagging links by hand. Postiz: No — its analytics track impressions, likes, comments and shares; nothing connects to a payment processor. Neither connects a payment processor to individual posts, which is the gap seenpaid fills.
