Postiz is an open-source social media scheduling tool that plans, generates, and publishes posts to 30+ networks from one visual calendar, with AI agents and an API.
About Postiz
What Is Postiz
Postiz is a social media scheduler for people who post to more than one network and don't want to open every app. You connect your social media accounts once, write a post, and pick the networks it should reach. Postiz handles the timing.
The product does two jobs. One is classic scheduling: a calendar, a composer, per-channel previews, and team workflows. The other is newer. Postiz ships a CLI, an MCP server, and a public API so AI agents like Claude, ChatGPT, or Codex can draft and schedule posts straight from a chat.
The main constraint is cost at the entry level. Postiz Cloud has no free plan. The app stays behind a plan picker until you subscribe, and new organizations usually get a 7 day trial instead. Teams that want to avoid subscriptions entirely can run the open-source version themselves.
Getting Started
- Sign up at postiz.com and pick a plan, or start the 7 day trial.
- Connect a channel from the left sidebar. Cloud registers the developer apps for you, so most networks connect in a couple of clicks.
- Open the composer, select the channels, and write once in the Global tab. Switch to a single channel's tab if that network needs its own wording.
- Set a date and time, then save it as a draft, add it to the calendar, or post now.

Key features
Agentic scheduling through MCP and CLI
Postiz connects to AI agents through an MCP server and a command-line tool. Prompt Claude, ChatGPT, Codex, or OpenClaw and the agent drafts posts, picks channels, and schedules them on your calendar. The same plumbing backs the public API, so anything the dashboard does, an agent can do too.
Publishing to 30+ social networks
X, LinkedIn, Facebook, Instagram, Threads, Bluesky, TikTok, YouTube, Reddit, Pinterest, Telegram, Discord, Mastodon, and more all connect from one workspace. These cover the social media platforms most teams already use. You pick channels per post, and each platform keeps its own settings where required, like a YouTube title or a Reddit subreddit.
Visual calendar and per-channel previews
The calendar holds every scheduled post, draft, and published item in one view. A preview column renders each post the way its target platform will show it, which catches a broken line break or a cut-off title before it goes live.
AI writing, image, and video tools
An AI copilot writes and refines captions, and a built-in editor lets you design images or generate them from a prompt. Video clipping takes a long YouTube video, cuts the moments that work on their own, and renders each as a captioned vertical short.
Automation plugs and RSS auto-posting
Milestone plugs watch for a condition, like 100 likes on a post, and then auto-comment or auto-like to keep a good post moving. RSS auto-posting pulls new feed items into the calendar, with AI rewriting on or off. Both run inside the tool, without a separate automation service.
Open source with a public API
The whole application is open source, so you can install it with Docker Compose and skip the subscription. A public API, an OAuth2 flow for apps that act for other users, and a Node.js SDK cover anything you'd rather script than click.
Pros and cons
Pros
- One calendar for 30+ networks means you stop opening a separate app per account.
- Every paid plan includes the API, CLI, and MCP server, so agents and scripts work from the $29 tier up.
- The open-source core lets teams self-host and run the full feature set with no plan gate.
- RSS auto-posting and milestone plugs keep feeds and top posts moving without manual work.
- OAuth2 and an SDK make it realistic to publish on behalf of your own users.
Cons
- Postiz Cloud has no free plan. Without a subscription, the interface stays on the plan picker, so you can't test it past the 7 day trial unless you self-host.
- Channel count is the only hard limit, and the entry tiers cap it low. Going past 5 channels on Standard means a higher plan, not an add-on.
- On self-hosted installs you register a developer app for most networks and supply your own API keys, which is real setup work.
- AI images, AI videos, and clipping are metered credits on cloud, so heavy AI use runs out of allowance before the month ends.
Frequently asked questions
No. Postiz Cloud has no free plan, and the app is locked behind the plan picker until you subscribe. New organizations usually get a 7 day trial instead. The open-source version is free to run yourself, with no plan limits.
