The scheduling calendar
Social media scheduler for 30+ networks that AI agents can drive through MCP, a CLI and an API; open source to self-host
Postiz has a 7-day free trial. Prices in US dollars as AdPostiz's pricing page showed them on 11 October 2026.
Postiz is a social media scheduler that publishes to more than 30 networks from one calendar and lets AI agents such as Claude and ChatGPT draft and schedule posts through its MCP server, CLI and API. It suits creators, agencies and developers who automate posting. The hosted service starts at $29 a month for five channels, or $23 a month billed yearly, after a 7-day free trial. The open-source edition is free to self-host.
Plan, preview and publish posts to X, LinkedIn, Instagram, TikTok, YouTube, Reddit, Threads, Bluesky, Discord, Slack and more from one calendar, with day, week and month views and per-channel settings.
Claude, ChatGPT, Codex, Cursor, Gemini and other agents connect through the hosted MCP server, the Postiz CLI or an installable skill. Posts they create land in the calendar for a person to approve.
A built-in, Canva-like editor with Unsplash photos, plus AI image and video generation and AI clipping that turns long YouTube videos into short captioned vertical clips.
Internal plugs repost or comment from your other accounts, and global plugs act when a post hits a threshold, such as reposting at 100 likes.
Schedule follow-up comments and threads, repeat evergreen posts, add delays, save channel sets with custom messages, append signatures and auto-post from RSS feeds.
Impressions, likes, comments, shares and engagement for each connected channel over a chosen period.
Invite team members to collaborate, comment and schedule, and group channels into customer folders for agencies managing several brands.
A public REST API, webhooks, a Node.js SDK and n8n and Make integrations. The whole platform is open source under AGPL-3.0 and can run on your own server with Docker.

“Good tool for social media campaigns. The great thing is that the platform constantly evolves - new features appear all the time”
“sometimes posting from a third party app also impacts the reach of posts on certain platforms”
Postiz Cloud costs $29 a month for 5 channels, $39 for 10, $49 for 30 and $99 for 100, billed in US dollars. Paying yearly cuts those to $23, $31, $39 and $79 a month, a saving Postiz puts at about 20%.
Every plan has unlimited posts, the API, webhooks, the MCP server, analytics and the AI copilot. What changes is the channel count, team access and the AI allowance: Standard has no team members, while Team and above allow unlimited team members and add AI images, more AI videos and more minutes of AI video clipping. There is no free hosted plan, only a 7-day trial. The pricing page doesn't mention VAT, and subscriptions are sold by Gitroom Limited, a Hong Kong company, which also handles refunds and tax invoices according to the terms.
Yes. The open-source edition on GitHub is free under the AGPL-3.0 licence, and Postiz says it doesn't hold features back from it.
The catch is the work involved. Self-hosting means running Postiz with Docker or on a VPS and setting up Postgres, Redis, storage and environment variables yourself. You also have to create your own developer apps on each social network and pass their approval, which the Postiz README warns can take weeks for Meta, YouTube and TikTok. Postiz Cloud skips all of that with pre-approved apps. For a developer comfortable with servers, the free edition can replace a paid scheduler; for most small businesses the hosted plan is the realistic option.
Postiz usually costs less once you manage many accounts, while Buffer is the safer pick for someone who wants a free plan, mobile apps and a long track record.
The pricing models differ. Buffer charges per channel, so 10 channels on Buffer's Team plan cost $120 a month billed monthly, against $39 for 10 channels with unlimited team members on Postiz's Team plan. For one to three accounts, Buffer's free plan beats Postiz, which has no free hosted tier. Postiz also covers networks Buffer doesn't, including Reddit, Discord, Telegram, Slack, Dribbble and WordPress. Buffer has far more reviews behind it (126 on Trustpilot against 11 for Postiz) and apps for iPhone and Android. Zernio is the other option to weigh, aimed at developers posting through an API.
Yes, and it is the main thing Postiz builds around. Every plan includes a hosted MCP server, a command-line tool and a public API, so agents such as Claude, ChatGPT, Codex, Cursor and Gemini can create and schedule posts.
Postiz says posts an agent creates land in your calendar first, so a person can review, edit or reschedule them before anything goes live. The Smart Agent inside the app does the same through a chat window. There are also n8n and Make integrations for people who automate without code. A Trustpilot reviewer on the top plan reported their agent couldn't post, so automations are worth testing during the trial.
Postiz connects to social networks through official developer apps held by Gitroom LLC, its US company, so you authorise each account rather than sharing passwords.
Its privacy policy says Postiz operates from Hong Kong and the United States and uses sub-processors in the US, the EU, the UK and elsewhere, with UK GDPR legal bases set out for each use of data. Agencies with strict data rules can self-host the open-source edition instead, which keeps content on their own servers.
