The product
Postiz is a scheduling tool for social media. You write a post once, choose the channels, set the time and see everything in a visual calendar before it goes out. It also has a built-in image editor, an AI assistant for writing and rewriting copy, and analytics so you can see how posts perform. It covers networks such as X, LinkedIn, Instagram, TikTok, YouTube, Reddit, Threads, Bluesky and Discord.
The AI side
Postiz calls itself an agentic scheduler. AI agents such as Claude, ChatGPT, Cursor and OpenClaw can draft and schedule posts through its MCP server, command line tool and API. Posts an agent creates land in your calendar first, so you can review, edit or reschedule them before anything is published.
Who it suits
Creators and small brands who want one calendar for many channels, agencies handling several clients, and developers or automation teams who want to build on its public API and webhooks, or connect it to n8n or Make. The same tools are open to teams, with members invited to a shared workspace where posts can be assigned and checked. It was started by Nevo David, a developer and marketer who wanted one place to schedule everything he published.
Pricing
The hosted service has a seven-day free trial and then monthly plans that scale with the number of channels, team members and AI allowance. Yearly billing is cheaper than monthly. Prices are in US dollars and the pricing page is where current figures live. There is no free hosted plan.
Self-hosting
The open-source edition is free under the AGPL-3.0 licence. The trade-off is the work: you run it yourself, set up the database and storage, and create your own developer apps on each network, which can take time to get approved. The hosted version handles all of that.
Saving
Any live code for Postiz is listed on this page. Copy it and enter it at checkout. Yearly billing is also the usual way to pay less.
