Postiz is an open-source social media scheduling application designed as an alternative to commercial tools like Buffer, Hypefury, and Twitter Hunter. Built with TypeScript and licensed under AGPL-3.0, the project provides a comprehensive platform for managing social media posts across multiple networks including Instagram, YouTube, LinkedIn, Reddit, TikTok, Facebook, Pinterest, Threads, X, Slack, Discord, Mastodon, and Bluesky. The application emphasizes AI-driven features and agentic capabilities, positioning itself as an ultimate agentic social media scheduling tool with agent CLI support for integration with platforms like OpenClaw.
The technical architecture uses a monorepo structure with Pnpm workspaces, combining NextJS for the frontend React interface with NestJS for the backend. The stack includes Prisma for database operations defaulting to PostgreSQL, Temporal for workflow orchestration, and Resend for email notifications. This architecture supports both hosted and self-hosted deployments with feature parity between the two versions, making it suitable for users seeking either managed or on-premises solutions.
Core functionality encompasses scheduling social media posts with AI enhancements, measuring work through analytics dashboards, and enabling team collaboration where members can exchange or purchase posts. The platform supports team member invitations for collaborative commenting and scheduling, and provides API access for automation integration with platforms like N8N, Make.com, and Zapier. The project includes a NodeJS SDK available on NPM and custom integrations for N8N and Make.com, extending its utility for developers building automated workflows.
The repository overlaps contributors with notable projects including Sentry, Twenty, and AIONUI, suggesting cross-pollination with other significant open-source initiatives. Postiz emphasizes compliance and data privacy, explicitly stating that it does not automate or scrape content from social platforms, does not collect or store API keys, and never requests users to paste credentials into the hosted product. Instead, users authenticate directly with social platforms through official OAuth flows, ensuring platform compliance and maintaining user data security.
The project maintains comprehensive documentation at docs.postiz.com, operates a YouTube channel for tutorials, and provides a developer-focused Discord community. Sponsorship opportunities are available through OpenCollective, with the project noting approximately 6 million downloads and 20,000 monthly views. The platform is supported by sponsors including Hostinger for VPS infrastructure, Virlo for social media trend analysis, and ChatbotX for chatbot capabilities, reflecting its positioning within the broader ecosystem of social media and automation tools.
