Same facts, side by side: starting price, free tier, MCP, API and what each one is actually built for.

Starting price

Buffer

$5/channel/mo Free tier 14 day free trial

Social media scheduler with a free three-channel plan. Paid Essentials is $5/channel/mo billed yearly ($60 per channel per year).

Where Buffer fits

  • Creators scheduling LinkedIn and other networks from one queue
  • Teams that want MCP on the free plan
  • Developers using the Buffer API
  • Small brands that want low per-channel pricing

Postiz

$29/mo 7 day free trial

Where Postiz fits

Where they pull apart

Buffer

Stands out: MCP is included on the free plan, so Claude or ChatGPT can draft and queue posts without a paid seat.

Watch out: The $5 figure is per channel on yearly billing; monthly costs more. Free caps you at 10 scheduled posts per channel and one user.

Not the right fit for

  • Newsrooms that need a full social suite beyond scheduling
  • Users who only want LinkedIn commenting, not a multi-network queue

Postiz

Stands out: Agent access is the product, not an add-on. Every plan includes a hosted MCP server with OAuth sign-in, a CLI skill and a public API, so a recruiter can ask Claude to turn one job post into LinkedIn, X and Facebook versions and schedule them for the week. The AGPL-3.0 code on GitHub has over 37,000 stars.

Watch out: There is no permanent free plan on the cloud version, and the $29 Standard plan is solo only with no AI images. Self-hosting is free but means running Docker yourself and getting your own developer app approved by Meta, TikTok and YouTube, which can take weeks. It is a general social tool, so it has no job posting, ATS or candidate features.

Not the right fit for

  • Recruiters who only need LinkedIn and want writing help (a LinkedIn-first tool fits better)
  • Buyers who want a permanent free plan
  • Teams that need job distribution to job boards or ATS integration
