Postiz review for scheduling social posts with AI agents

Postiz is a social media scheduler built for AI agents: you, or a tool like Claude or ChatGPT, plan and schedule posts to more than 30 networks, and everything lands in one calendar for review. It suits creators, small brands and agencies that want automation and an API on every plan. Skip it if you want a free hosted plan.

What Postiz is

Postiz is a social media scheduling platform from Gitroom Limited, available as a hosted cloud service and as open-source software you can run yourself. It was founded by developer and marketer Nevo David, who wanted one place to schedule everything without per-channel limits.

The hosted version is the main product, and the vendor says new agent features ship there first. The open-source code on GitHub is licensed under AGPL-3.0 and has about 41,100 stars and 7,800 forks, a large following for an open-source social scheduler.

Who Postiz is for, and who should skip it

Postiz is a good fit for anyone who already uses AI agents or automation tools and wants them to draft and schedule posts while a person approves the calendar. Its plans scale from a single creator with five channels to agencies managing up to 100.

• Good fit: solo creators posting to many networks, developers building on its API, marketers running n8n or Make workflows, and agencies that group channels by client.
• Skip it if: you only post to one or two networks and want a free tool, you need a social inbox for replying to messages, or you want enterprise approval workflows and listening.

How Postiz works: calendar, AI agents and automation

Postiz works around a visual calendar. You connect channels, write a post once, pick the networks and time, and preview it before it goes out. AI agents connect through a hosted MCP server, the Postiz CLI or an installable skill, and anything they create lands in the calendar first.

• Cross-posting and scheduling: one post to any connected channel, with per-channel settings, post delays, repeated posts for evergreen content and RSS auto-posting from a blog or newsletter.
• AI tools: an AI copilot for copy, AI images and videos, and AI video clipping that turns a long YouTube video into vertical clips with captions.
• Design: a built-in Canva-style picture editor with Unsplash photos and AI image generation.
• Plugs: set a milestone, such as 100 likes, and Postiz can auto-post, auto-like or auto-comment.
• Team features: unlimited team members from the Team plan, customer groups to sort channels by client, sets and signatures.
• Analytics: per-channel and per-post impressions, likes, comments, shares and engagement rate pulled from each network.

For agents, the MCP server signs in with OAuth and no API key, and the vendor documents setups for Claude, ChatGPT, Cursor, Codex, Gemini and others. A public REST API, webhooks, an n8n node, Make and Zapier cover regular automation.

Postiz pricing

Postiz pricing starts at $29 a month for Standard, or $23 a month billed yearly, which saves about 20%. Every plan has a 7-day free trial and unlimited posts, and agent access, the API and webhooks are on every plan. Prices checked 8 Nov 2026 on postiz.com, in US dollars.

Clipping uses one minute per minute of source video, however many clips come out of it, and failed clips are refunded. On money, Postiz refunds up to one month of fees per account if your last charge was within 120 days, but annual plans are not refundable. You can change or cancel a plan at any time.

What a typical user pays

A creator posting to X, LinkedIn, Instagram, TikTok and YouTube fits Standard at $29 a month, or $276 a year on yearly billing. A small agency with 12 client channels outgrows Team's 10 and needs Pro at $49 a month, or $39 a month billed yearly. Each connected account counts as one channel, and you can swap channels at any time.

Can you self-host Postiz with Docker?

Yes, Postiz can be self-hosted from its GitHub repository, which includes Docker files and a self-host guide in the docs. The vendor calls self-hosting a secondary option, and you need your own developer apps approved by each network. Postiz offers that approval as an optional paid service, and says Facebook, Instagram, Threads and YouTube approvals usually take more than a month.

What users say about Postiz

Postiz has strong community signals, though fewer structured ratings than older schedulers. Its GitHub repository has about 41,100 stars, and the vendor says Postiz was Product Hunt's number one product of the day, week and month.

The posts on its homepage, from users on X, praise how easily AI agents can post through it, the number of supported networks and the time saved by queuing a week of content. One self-hosting marketer calls it the best social management tool they have used. These quotes are picked by Postiz.

Postiz channels, integrations and company facts

Postiz supports more than 30 channels from one calendar and runs as a web app. The vendor lists:

• Channels: X, LinkedIn profiles and pages, Facebook Pages, Instagram, Threads, TikTok, YouTube, Pinterest, Reddit, Bluesky, Mastodon, Lemmy, Farcaster, Nostr, Telegram, Discord, Slack, VK, Google My Business and more.
• Agents and automation: hosted MCP server, CLI and skill, official connectors for Claude, ChatGPT, Cursor and Grok, plus REST API, webhooks, an SDK with OAuth2, n8n, Make and Zapier.
• Open source: AGPL-3.0, with 204 releases on GitHub.
• Company: Gitroom Limited in Hong Kong is the contracting party, and Gitroom LLC in Dover, Delaware holds the social platform developer approvals.

What changed recently in Postiz

Postiz releases often, and recent versions include security fixes. Version 2.25.3 (24 Oct 2026) fixed two security vulnerabilities and the release notes tell all users to upgrade at once, which matters most if you self-host. Earlier October releases added preview comments, a self-hosted MCP connector, a responsive app and fixes for more than 50 providers, and 2.24.0 brought streamed media uploads and duplicate-post protection.

Postiz limits and drawbacks

The main drawback is that there is no free hosted plan, only a 7-day trial. Other limits worth knowing:

• Standard does not include team members, so collaboration starts at $39 a month.
• Annual plans cannot be refunded.
• Self-hosting means getting your own app approvals from each network, which can take weeks, and keeping up with security releases.
• AI images are not listed on Standard, and AI video and clipping minutes are capped per month.
• Analytics depend on what each network's official API returns.

Postiz alternatives

These Postiz alternatives also schedule posts across many networks, several with agent access of their own:

• dopost: pick it if you want a free plan and team workspaces across 12 networks, also with an API and MCP server.
• SocialClaw: pick it if you are a founder or developer who wants an agent-first scheduler with a REST API, MCP server and CLI.
• Ocoya: pick it if you want AI to write and design posts and need a social inbox across 28 networks and apps.
• Buffer: pick it if you post to a handful of channels and want a long-established scheduler with a free plan.
• Mixpost: pick it if you want a self-hosted social media manager you own outright and prefer a different code base to Postiz.

Verdict

Postiz is one of the best fits for creators and agencies who want AI agents, n8n or their own code to schedule social posts, with the API, MCP server and unlimited posts on every plan. I would pick it over older schedulers for automation-heavy work, but anyone who wants a free plan or a social inbox should look at the alternatives.
