Postiz

Postiz is an open-source social media management and scheduling tool that lets you plan, schedule and publish content across all your social channels from one place — and crucially, you can self-host it for full control and cost savings. It positions itself as an open alternative to popular but pricey social scheduling tools, giving creators, marketers and small businesses a capable way to manage their social presence without ongoing subscription fees or vendor lock-in.

The platform covers the essentials of social media management: connecting multiple accounts across major platforms, composing and scheduling posts, managing a content calendar, and publishing to several channels at once. This saves the considerable time and hassle of posting manually to each network and helps maintain a consistent presence, which is essential for growing an audience. By having everything in one dashboard, users can plan their content ahead, batch their work, and keep their channels active without constant manual effort.

Postiz's open-source, self-hostable nature is its biggest differentiator. Teams and individuals who want to avoid the recurring costs of commercial schedulers, who value owning their data and infrastructure, or who want to customize and extend the tool can run Postiz themselves, while a hosted option offers convenience. It has also embraced AI to help with content creation and scheduling. This combination of open source, AI features and a modern interface has made it popular with developers, indie makers and cost-conscious creators who want powerful social scheduling on their own terms. As social media management remains essential but commercial tools grow expensive, an open, self-hostable alternative is genuinely appealing. For creators, marketers and businesses that want to schedule and manage their social media across channels — with the freedom, control and economics of open source — Postiz offers a capable, modern and refreshingly open solution.
