OpenCutA free and open source video editor for web, desktop, and mobile. |
Status
OpenCut is being rewritten from the ground up. What’s coming:
- An Editor API
- First-class third party plugins (made possible by a plugin-first architecture)
- Desktop, mobile, and browser from one codebase (Rust core)
- MCP server (for AI agents)
- Headless mode (automation, batch rendering)
- A scripting tab directly in the editor
You can still find the previous version at opencut-app/opencut-classic, which is the one to reach for today. opencut.app still runs the classic version. The rewrite will live at new.opencut.app until it’s ready to take over.
