OpenPost

Overview

OpenPost is an open-source tool introduced via a recent Show HN post as an alternative to Buffer, CapCut, and Canva, aimed at automating social content and video workflows.[15] While positioned for creators, it exposes APIs and a modular backend that developers can extend with AI models for generation, scheduling, and analytics. Its open architecture makes it relevant for engineers building custom marketing or media automation stacks with model-based content generation.[15]
