Postiz

Open-source social media scheduler that AI agents can drive

Postiz plans, schedules and publishes posts to more than 30 social networks, including X, LinkedIn, Instagram, TikTok, YouTube, Reddit, Bluesky and Mastodon. You write a post once, see a preview for each channel and review everything in one calendar. It also has analytics, team roles, a built-in design editor with AI images, RSS auto-posting and repeating posts.

AI agents such as Claude, ChatGPT and Cursor can draft and schedule posts through its hosted MCP server, a CLI, or a public REST API with webhooks. It also works with n8n, Make.com and Zapier.

Postiz Cloud is paid (prices in USD), with a 7-day free trial: Standard $29/month (5 channels), Team $39 (10), Pro $49 (30), Ultimate $99 (100). Yearly billing is about 20% less. The code is open source under AGPL-3.0 and can be self-hosted with Docker; the maker says cloud and open source have the same core features.

対応対象

Solo creators, small brands and agencies that manage social media, plus developers and automation teams who build on its API, MCP server or n8n and Make.com integrations.
