PostOnce is a social media automation platform that lets creators, teams, and agencies post once and automatically crosspost content to TikTok, Instagram, YouTube, Facebook, LinkedIn, X, Threads, Bluesky, and Pinterest. Users connect their social accounts via OAuth, build automated publishing workflows, and repurpose existing content across channels without repeating the upload process for each platform. It also offers a Developer API and MCP integration for programmatic and AI-assistant publishing.
