OpenMontage is an open-source, agentic video production system with more than 70,000 stars on GitHub that turns your AI coding assistant into a full video production studio.
OpenMontage describes itself as the world’s first open-source agentic video production system. Instead of a timeline editor, you direct production pipelines: the system ships 12 production pipelines, more than 100 tools and over 700 agent skill and production-knowledge files that teach assistants like Claude, Copilot and Cursor how professional video gets made. Under the hood it composes technologies such as FFmpeg and Remotion with image generation models like FLUX and Stable Diffusion, text-to-speech from providers such as ElevenLabs, and OpenAI models for scripting and planning. The result is end-to-end text-to-video and video-generation workflows driven by an agent rather than manual editing. The project is written in Python, actively maintained with pushes in October 2026, and released under the AGPL-3.0 license.
The project matters because it treats video production as an agent-orchestration problem: research, scripting, asset generation, voiceover, editing and rendering become stages an assistant can execute and revise on instruction. For teams producing content at volume, that turns video from a craft bottleneck into a repeatable pipeline that can generate variations for different platforms and audiences from a single brief.
OpenMontage is completely free and open source under the AGPL-3.0 license. You run it locally and only pay for any third-party model or voice APIs you choose to plug in.
Creators, marketers and developers who want to produce videos programmatically — faceless channels, explainers, shorts and product videos — by directing an AI agent instead of editing timelines by hand.
