Crossposter

Crossposter is a free, open-source tool that lets users publish content to multiple social media platforms directly from their local machine, eliminating the need for third-party services. It is designed for developers, privacy-conscious creators, and anyone who wants full control over their social publishing workflow without relying on proprietary APIs or cloud dependencies. Its interest lies in combining local-first autonomy with multi-platform reach, offering a transparent, self-hosted alternative to centralized scheduling tools.
