Postiz

Postiz centralizes scheduling and publishing content across multiple social networks, with agentic functions to generate or adapt content per platform, as an open-source alternative to SaaS social media management tools.

Postiz's publishing calendar

Key advantages

  • Open source and self-hostable
  • Agentic functions for content adaptation
  • An alternative to SaaS social media management subscriptions

Who it's for, and why

Marketing teams or creators managing several social accounts who want a self-hostable tool rather than a SaaS subscription.

  • Scheduling posts across multiple social networks
  • Automatically adapting content per platform
  • Centralizing the social media editorial calendar

Getting started

  1. 1Recommended option: Docker Compose, following the official guide at docs.postiz.com/installation/docker-compose.
  2. 2Single-container alternative: `docker create --name postiz -v postiz-uploads:/uploads/ -v postiz-config:/config/ -p 5000:5000 ghcr.io/gitroomhq/postiz-app:latest` (Postgres and Redis needed separately).
  3. 3Simplest option with no self-hosting: Postiz's managed cloud service.

Things to watch out for

  • Full self-hosting requires managing Postgres and Redis in addition to the app container: more operational overhead than a plain SaaS.
  • The agentic content-adaptation functions are only as good as the AI model connected behind them: editorial oversight remains necessary before publishing.

Frequently asked questions

Is Postiz free when self-hosted?

Yes, the code is open source and self-hosting only costs infrastructure. A paid cloud offering exists for those who'd rather not manage a server.

Can it publish automatically with no human review?

Technically yes via automation rules, but human review is recommended before publishing on brand accounts, as with any AI-generated content.

How many social networks are supported?

The project covers the main networks (LinkedIn, X, Instagram, TikTok, YouTube and others); check the official documentation for the up-to-date list, which changes regularly.
