postiz-app: From social media scheduling to AI agent integration

Postiz is a platform for scheduling, automating, and analyzing social media content. It allows you to schedule posts across multiple channels simultaneously and manage collaboration and approval workflows among team members. You can build content distribution pipelines by integrating with automation tools and APIs such as N8N, Make.com, and Zapier.

It features built-in AI capabilities to support content generation and analysis. It offers AI Copilot, image and video generation, and smart agent features, and can extend workflows by connecting to various AI agents such as MCP, CLI, Claude, ChatGPT, and Codex. You can also connect your own LLM keys for unlimited usage.

It is available in two modes: cloud hosting and open-source self-hosting. The open-source version is distributed under the AGPL-3.0 license and supports all channels and an unlimited number of posts without feature restrictions. It is structured as a monorepo based on Next.js, NestJS, PostgreSQL, Redis, and Temporal, making it easy to customize.

It is suitable for teams that need to manage large numbers of social media channels or build AI-based content automation. The self-hosting option is useful for developers who prioritize data sovereignty or want to move beyond the feature limitations of existing SaaS tools. Users must handle the app approval process for each platform themselves.
