A Postiz alternative for AI agents

Looking for a Postiz alternative because your AI agent writes the posts? Postiz is open source, publishes to 30+ networks, and gives agents an MCP server, a CLI and a skill. UniPost publishes to fewer networks, but the first 2 accounts are free and it costs less at every size Postiz sells. Your agent schedules and approves posts through one MCP server, or sends you a review link first.

Postiz alternative for OpenClaw, Claude and other agents

Postiz connects agents three ways: a hosted MCP server, the Postiz CLI, and a skill installed with npx skills add gitroomhq/postiz-agent, which it lists for OpenClaw, Hermes and Codex. UniPost is a hosted MCP server at https://mcp.unipost.ai/mcp. Claude, Claude Code, ChatGPT, Codex, Cursor, Gemini CLI, Grok Bot and other HTTP MCP clients add the URL and sign in with OAuth, or use a workspace API key. Agents that read Markdown skills, such as OpenClaw and Hermes, can install the UniPost skill with npx skills add ajhous44/unipost-agent. It documents the server, the approval rule and every tool. UniPost has no CLI and no separate REST API.

Who stops a bad post from going live?

On Postiz, review happens in its calendar or through a preview link a client can comment on. Its docs say approval is "a conversation, not a state": there is no approved flag that blocks publishing, and the MCP schedule tool can publish right away. On UniPost, every post your agent schedules stays pending until it's approved. You can approve it in three ways: the approval link, the dashboard, or your agent. Your agent can approve a post it scheduled for you, so tell it to show you the full text, images, and time first. UniPost's server instructions tell agents never to approve a post you haven't seen and agreed to. If a teammate's agent created the post, your agent can't approve it; it has to be approved through the link.

Networks: where Postiz is ahead

LinkedIn profiles, X, and TikTok, with Facebook Pages and YouTube in beta. Instagram is coming soon. Postiz publishes to 30+, including Instagram, Threads, Reddit, Pinterest, Bluesky and LinkedIn company pages. If you need one of those today, Postiz is the better pick.

Posting to X from an agent

X charges per post, and more for a post with a link. UniPost counts a plain X post as 1 credit and a link post as 13. The free plan includes 10 credits a month, and paid plans include 50 for each of the first 10 X accounts and 20 for each one after. Your agent can call get_x_allowance to check what's left before it schedules.

Self-hosting and open source

Postiz publishes its code on GitHub under AGPL-3.0, and you can run it with Docker for the cost of your server. You also create a developer app on each network and handle updates, backups and API approvals yourself. Postiz's pricing page calls self-hosting "a secondary option" and says agent features ship first on the hosted version. UniPost is hosted only and isn't open source.
