Postiz is an open-source, self-hosted social media scheduling platform designed for marketers, agencies, and teams looking to manage multiple social platforms without relying on proprietary SaaS tools. Built with TypeScript, Next.js, and NestJS, it provides a full-featured alternative to Buffer and Hypefury while prioritizing data privacy and platform compliance. Unlike hosted alternatives, Postiz never collects or proxies your API keys — users authenticate directly with platforms like X (Twitter), Bluesky, Mastodon, and Discord via official OAuth flows. The tool is ideal for organizations that require full control over their data, need automation integrations, or want to avoid vendor lock-in.
Postiz supports AI-assisted content creation, team collaboration, detailed analytics, and seamless integration with automation tools like N8N, Make.com, and Zapier. Its monorepo architecture using pnpm workspaces ensures scalability, while Temporal handles background job orchestration and Prisma manages data persistence via PostgreSQL. With nearly 3 million Docker downloads and strong community adoption, Postiz is a robust, transparent solution for teams serious about social media growth without compromising security.

Under The Hood
The project is a comprehensive, multi-tiered application built as a monorepo that integrates backend services, a frontend web interface, and a browser extension into a unified platform. It emphasizes modularity and extensibility, supporting diverse third-party integrations and cross-platform functionality.
Architecture
This system adopts a modular monolithic structure with clearly defined applications for backend, frontend, and browser extension, each managing distinct responsibilities.
- The architecture follows a layered design with well-separated concerns between services and components
- It implements a provider-based modular system enabling flexible integration with external platforms like Farcaster and GitHub
- The codebase supports a unified API layer that serves both internal and external consumers with public and private endpoints
- Cross-platform extension design allows seamless interaction between web UI and browser-based tools for content automation
Tech Stack
The project leverages modern TypeScript-based frameworks and tooling to support its multi-layered architecture.
- Built primarily with TypeScript, NestJS for backend services, and Next.js for frontend rendering
- Integrates Prisma for database operations, Sentry for error tracking, and React for UI development
- Uses Vite for browser extension builds and Docker configurations for deployment flexibility
- Jest is employed for testing across modules, with CI/CD pipelines in place to support development workflows
Code Quality
Code quality shows a mixed state with some structured patterns but gaps in consistency and coverage.
- Linting and type safety are configured, supporting code reliability and maintainability
- Error handling is present but not uniformly applied across all modules and services
- Testing practices are in place but lack comprehensive coverage across key components
- Component architecture is strong, though some modules show inconsistency in code style and structure
What Makes It Unique
This project distinguishes itself through its unified ecosystem that bridges content creation, automation, and social media management.
- A modular provider architecture enables extensible authentication and integration with a wide range of third-party services
- The cross-platform browser extension design allows users to interact with the system directly from their browsers
- Built-in permission and subscription handling offers granular access control for enterprise-grade use cases
- The backend API is designed to support both internal workflows and external integrations with public/private endpoint differentiation
