Postiz is an open-source social media management platform that lets you write a post once and publish it to 30+ networks simultaneously. Each channel gets its own preview before you schedule, so you can adjust copy, hashtags, or media per platform without duplicating your whole workflow. A visual calendar shows everything at a glance, including recurring posts and upcoming auto-repeats.

The built-in AI agent can draft captions, generate images, and produce short video clips from a single chat prompt. You can instruct it to write a LinkedIn post, attach a matching image, and schedule it for a specific time, all in one go. Postiz also connects to external AI tools including Claude, ChatGPT, and Codex via an MCP server and CLI.

For teams and agencies, paid plans support unlimited members, customer groups for organizing multiple brands, and per-group calendars and analytics. Analytics pull from each network's official API and display impressions, reach, engagement rate, and more in one dashboard. Tools like SocialPilot and Iconosquare cover similar ground, but Postiz adds self-hosting as an option.

Automation integrations include n8n, Make.com, Zapier, and a public REST API with webhooks. RSS auto-posting, available on Team plans and above, can turn a blog feed into a consistent posting cadence without manual input.

Plans start at $29/month for solo users (5 channels, 400 posts/month) and scale to $99/month for agencies managing up to 100 connected accounts. The codebase is open source and self-hostable for teams that prefer to run it on their own infrastructure.
