Show HN: Hookpost – Open-source social media scheduler with AI Agent copilot (github.com)

Hookpost has emerged as a new open-source social media scheduling tool that allows users to manage content across more than 30 platforms, including X (Twitter), Instagram, LinkedIn, and TikTok. This platform not only simplifies the scheduling process but also integrates powerful AI capabilities through its Multi-Agent AI Copilot, enabling users to generate posts, visuals, and even manage scheduling via familiar AI frameworks like Claude and ChatGPT. With features like a visual calendar, a built-in media suite for creating platform-specific content, and robust automation tools via REST API and webhooks, Hookpost aims to cater to creators, developers, and automation teams seeking an all-in-one solution. The significance of Hookpost lies in its commitment to user control and transparency, being completely open-source and self-hostable. Developers can run it locally with quick deployment via Docker in under a minute, allowing full ownership of data and flexibility in usage. This facilitates not only ease of accessibility but also customization opportunities for unique workflows. By addressing these critical needs in the rapidly evolving social media scheduling landscape, Hookpost positions itself as a comprehensive alternative to existing platforms like Postiz and Buffer, emphasizing automation and the integration of AI in content management.
