Postiz - Open-Source Social Media Scheduler

Postiz is an open-source social media management and scheduling tool. Compose once, schedule across platforms, collaborate with a team, and keep drafts and credentials on infrastructure you control—instead of paying Buffer or Hootsuite per channel.

Key Features

• Multi-Platform Publishing: Schedule posts across major social networks from one calendar.
• Team Workflows: Drafts, collaboration, and shared queues for agencies or creators.
• Calendar UI: Plan campaigns visually instead of ad-hoc posting.
• Self-Hosted Control: Docker deployment so content strategy stays private.
• Automation Friendly: Fits stacks that already use n8n/Activepieces.
• Open Source: Active GitHub project with community and cloud options.

Why Choose Postiz?

• Social schedulers get expensive as channels grow.
• You refuse to hand every draft to another SaaS.
• You already self-host marketing tools (e.g. Notifuse for email) and want social too.
• Apache-licensed / open core models beat pure closed SaaS for long-term ownership.

Docker Deployment

# Follow current Postiz self-host docs for compose + env
# https://github.com/gitroomhq/postiz-app
git clone https://github.com/gitroomhq/postiz-app.git
# configure .env (DB, redis, OAuth app keys per network)
docker compose up -d

You will need developer OAuth apps for each social network you connect—same as any self-hosted scheduler.

Getting Started

1. Deploy with Docker and complete initial setup.
2. Create OAuth apps on the networks you use and add credentials.
3. Connect accounts and schedule a test post.
4. Invite teammates and standardize the calendar.
5. Optional: automate sourcing posts via n8n.
