OpenMontage
World's first open-source, agentic video production system. 12 production pipelines, 100+ tools, 700+ agent skill and production-knowledge files. Turn your AI coding assistant into a full video production studio.
Project mention: An open-source 'AI crew' that turns a coding assistant into a video studio | dev.to | 2026-07-01The project's goal, stated plainly on its project page, is to be the 'world's first open-source, agentic video production system.' Stripped of the buzzwords, that means two things. 'Open-source' means anyone can read, run, and change the code for free, rather than paying a company for a locked product. 'Agentic' means it is built around AI agents, software workers that do not just answer a single question but take on a goal, break it into steps, use tools, and carry the steps out with limited hand-holding. OpenMontage ships with twelve pipelines (start-to-finish recipes for common production jobs), fifty-two tools the agents can pick up and use, and more than five hundred skills, small bundles of instructions that teach an agent how to do a specific task well.
