OpenMontage just hit #1 on GitHub Trending with 31K+ stars — and after watching the demo, I get why.

This is the first open-source agentic video production system. What does that mean? You type one sentence into Claude Code, Cursor, or Copilot, and your AI coding assistant handles the entire video pipeline: research, scripting, asset generation (stock footage + AI), voiceover, music, editing, and final render. No toggling between 15 apps. No manual timeline work.

The demo video shows the full workflow: paste a reference clip, the agent analyzes transcript/pacing/style, proposes differentiated concepts with cost estimates, and then executes end-to-end. They produced a cinematic sci-fi trailer, a Pixar-style animated short for .33, and a product ad for $.69 — all through plain language prompts.

12 production pipelines. 52 tools. 500+ agent skills. Works with Claude Code, Cursor, Windsurf, Copilot, Codex — anything that can read files and run commands.

For anyone building content pipelines or automating media workflows, this is the most exciting open-source release Ive seen this year. The age of "describe what you want and your AI agent builds it" is here.
