Postiz Review: A Social Media Scheduler Built for AI Agents

Postiz is a social media scheduler where AI agents such as Claude, ChatGPT or Cursor can queue posts through an MCP server included in every plan. Cloud plans run $29 to $99 per month on monthly billing, with no free plan. Choose it for agent-driven scheduling with human review; skip it if you need a free plan.

Postiz pitches itself as a scheduler where AI agents plan and schedule your posts while you review them.

Its home page headline reads "Run your social media on autopilot with AI agents." Its own MCP page, though, asks you to "make sure there is always a human in the loop." That gap shapes who should pay for this tool.

We analyzed Postiz's pricing page, help docs and MCP page on October 18, 2026, and compared them with Buffer and Hootsuite. We did not run our own tests. Nothing below says how well an agent writes or schedules for you.

What Is Postiz?

Postiz calls itself "the agentic social media scheduler": AI agents plan, generate and schedule posts, and you review them in one visual calendar. That is the company's own description.

The network list is long. It includes X, LinkedIn profiles and company pages, Facebook Pages, Instagram, Threads, TikTok, YouTube, Pinterest, Reddit and Bluesky, plus Mastodon, Telegram, Discord, Slack, WordPress and Medium. The home page says 30+ networks, while the CLI docs say 28+. Treat the count as marketing and check that your networks are on the list.

According to the pricing page, every plan also includes analytics, calendar views, cross posting, repeated posts, an API and webhooks.

How Does the Postiz MCP Server Work?

Postiz's hosted MCP server comes with every plan, along with the CLI, the public API and webhooks. There is no separate agent plan.

Setup uses one connector link that Postiz publishes on its MCP page. Postiz says the link is the same for every user and every client, and that it is not a secret. The MCP page says you sign in with OAuth when your client asks, with no API key needed. The docs describe authentication differently and mention an API key, and neither page explains how the two fit together. Check which method applies to your client.

Postiz names these clients: Claude.ai, Claude Code, ChatGPT, Cursor and Codex. It also says any client that supports remote MCP servers can use the link.

Through MCP, an agent can:

• List your connected channels
• Schedule or publish posts with per-platform settings
• List and manage scheduled posts
• Read per-platform settings
• Pull analytics for a channel or a post
• Upload media by URL

Image generation, video generation and clipping of long videos work only through a custom link or the ChatGPT connector. The Claude directory connector leaves them out. Postiz says the reason is that Anthropic's directory terms don't allow media-generation tools. Clipping accepts YouTube URLs only and creates drafts, never scheduled or published posts.

Where the Postiz MCP Falls Short

The limits matter more than the feature list here.

• A human stays in the loop. Postiz asks for it directly and suggests scheduling instead of publishing right away, so you can review the queue.
• No comments. The docs say there is no getComments or replyToComment exposed via MCP.
• Two descriptions of the tool set. The MCP page and the docs describe the tool set in different terms. Both are official, so check what your client can do before you rely on it.
• Key changes break clients. The docs say that if you regenerate your API key, every MCP client using the old key stops working until you update its config. Because the MCP page and the docs describe sign-in differently, confirm which method your client uses.
• No stated MCP limits. We found no MCP-specific rate limits or quotas on the MCP page or in the limits docs. If you plan to queue many posts a day, confirm this with Postiz first.

Postiz's own pages also disagree on a few details. The pricing page and the docs differ on whether the Standard plan includes AI images and RSS auto-posting, and the docs give different tool counts in different places. If one of those decides your purchase, confirm it before you pay.

How Much Does Postiz Cost?

All prices below were checked on October 18, 2026, and Postiz calls its pricing page the commercial source of truth. There is no free cloud plan. Here is what each plan costs on monthly billing and on annual billing, shown per month:

• Standard: $29 per month on monthly billing, $23 per month on annual billing. 5 channels, no team members.
• Team: $39 per month monthly, $31 per month annual. 10 channels, team members included.
• Pro: $49 per month monthly, $39 per month annual. 30 channels, team members included.
• Ultimate: $99 per month monthly, $79 per month annual. 100 channels, team members included.

Posts per month are listed as unlimited on every plan. AI images on Team, Pro and Ultimate are capped at 100, 300 and 500 per month. AI videos run 3, 10, 30 and 60 per month from Standard to Ultimate, and clipping minutes run 60, 120, 300 and 600.

Postiz says annual billing saves about 20%. The pricing page shows the annual rate only as a per-month figure, so check the checkout screen for what you are charged and when.

Refunds cover up to one month of fees per account, as long as your last charge was within the past 120 days. Postiz's FAQ says annual plans are not refundable. Promo codes apply to monthly plans only.

What Does the 7-Day Trial Include?

Postiz offers a 7-day free trial on every plan. The pricing page buttons say "Start for $0" and don't mention a card. The trial docs do: starting a trial requires a payment method, and at day 7 your card is charged for the plan you chose. Cancel before day 7 to avoid the charge.

The trial also has a catch for an AI-first tool. Some AI video generators and video clipping stay unavailable until the trial converts. Each organization gets one trial.

Postiz vs Buffer vs Hootsuite

These three price in different ways, so we compare structure and avoid converting totals. Postiz sells a plan with channels included. Buffer bills per channel. Hootsuite bills per user. In the entry-price row, each cell uses its own company's unit, so don't compare the cells directly: Postiz's figure covers 5 channels, Buffer's covers 1.

Buffer. The Free plan connects up to 3 channels, with 10 scheduled posts per channel and 1 user. Paid plans are billed per channel: for the first 10 channels, the help center lists Essentials at $6 per channel monthly and Team at $12, or $60 and $120 per channel billed yearly. Buffer's MCP page says access is included on every plan, including Free. It lists creating and scheduling posts, managing the queue, saving ideas and viewing channels and upcoming content, and says more capabilities are coming. The page also says posts land in the queue for review.

Not ideal for: anyone who wants image generation or video clipping through MCP, since Buffer's MCP page doesn't list them.

Hootsuite. The plans table is labeled per user per month, billed annually, and the FAQ says paid plans start at $99 for Standard and range up to $399 for Advanced, without stating the billing period. We could not confirm a monthly price. Standard manages up to 10 social accounts, and Professional and above list unlimited accounts. The 14-day trial needs no credit card.

Not ideal for: anyone who wants to compare a monthly price before signing up. Check the current price on the official site.

Can You Self-Host Postiz?

Yes. Postiz says the open-source version is the same codebase, published on GitHub under the AGPL-3.0 license. You can self-host it with Docker if you want full control over your data or want to run it for free.

Postiz also calls self-hosting a secondary option and says the hosted platform gets agent features first. When you self-host, you handle the server, the developer apps for each network and the updates. That suits someone comfortable running infrastructure, not someone avoiding a $29 bill.

Postiz at a Glance

Which One Should You Actually Use?

If you work in an AI client daily and want it to draft and queue posts for your review: pick Postiz, and schedule instead of publishing immediately.

If you manage up to 3 channels and want a plan with no monthly bill: start with Buffer's Free plan.

If you need an agent to answer comments: the Postiz MCP does not expose comment tools. We did not evaluate its CLI or API for that, so check before you count on it.

If you want control of your data: self-host Postiz, and budget time for the server and updates.

If you price by seat for a team: Hootsuite is structured per user. Check its current price first.

Because we did not test Postiz, treat the 7-day trial as your real test. Connect your own AI client, queue a few posts and see how much review they need.
