What it is

Postiz is an open-source social media scheduling tool built as a self-hosted alternative to commercial platforms like Buffer and Hootsuite. It enables users to schedule, manage, and analyze posts across multiple social networks—including X (Twitter), Bluesky, Mastodon, and Discord—while supporting AI-assisted content creation and team collaboration. The project lives in the Next.js and NestJS ecosystem, using a monorepo structure with TypeScript, Prisma (defaulting to PostgreSQL), and Temporal for background workflows.

Postiz solves the problem of fragmented, expensive, and closed social media management by offering a fully self-hostable, API-first platform. It eliminates vendor lock-in and recurring subscription costs, while ensuring compliance through direct OAuth authentication without storing or proxying user credentials.

Key capabilities

• Schedule posts across X, Bluesky, Mastodon, Discord, and other supported platforms
• AI-powered content generation and optimization via built-in agent CLI
• Team collaboration with shared queues, comments, and post exchange functionality
• Real-time analytics and performance tracking for published content
• Full REST and GraphQL public API with official Node.js SDK
• Native integrations for N8N, Make.com, and Zapier via custom nodes
• Email notifications via Resend, with configurable SMTP fallback

Who uses it and how

• Agencies and in-house teams self-host Postiz to manage client accounts securely without exposing credentials to third parties
• Developers integrate Postiz into automation pipelines using its public API and SDK for custom scheduling logic
• Open-source communities and indie hackers use the agent CLI to trigger social posts from external workflows (e.g., blog publishes, product launches)

Getting started

Deploy using Docker (postiz/postiz) or install via pnpm from source. The Quick Start Guide walks through environment setup, database initialization, and service startup. A hosted version is available at postiz.com for users preferring managed infrastructure.

When to use it — and when not to

Choose Postiz if you need full control over data, want to avoid per-seat/per-post pricing, or require deep API integration. Avoid it if you lack infrastructure resources to manage PostgreSQL, Redis, Temporal, and SMTP yourself—self-hosting requires operational overhead. Unlike Buffer or Hootsuite, Postiz does not offer native mobile apps or 24/7 enterprise support, and its agent CLI is newer with fewer prebuilt templates.
