Postiz

Postiz is an open-source social media scheduling and management platform built for creators, businesses, and agencies who manage multiple accounts across networks. It supports 19+ platforms — including X, Instagram, TikTok, LinkedIn, YouTube, Bluesky, and Reddit — from a single dashboard, replacing the need for tools like Buffer or Hootsuite. Postiz is self-hostable via Docker and licensed under AGPL-3.0, giving teams full control over their data and posting workflows.

The platform includes cross-channel scheduling, an AI content assistant for ideation and copy generation, built-in design tools, and performance analytics. Team collaboration features let agencies delegate work across clients with task management and approvals, while integrations with n8n, Make.com, and Zapier extend Postiz into broader automation workflows.

With 30k+ stars on GitHub and a v2.x release line that has matured into a stable product, Postiz is a credible open-source alternative in a market long dominated by closed SaaS tools. It is a strong fit for solo creators managing a personal brand, growing businesses coordinating multi-channel campaigns, and agencies juggling dozens of client accounts.
