OpenCut A free and open source video editor for web, desktop, and mobile.

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.

Install proto if you haven't already:

Linux, macOS, WSL:

bash <(curl -fsSL https://moonrepo.dev/install/proto.sh)

Windows (PowerShell):

irm https://moonrepo.dev/install/proto.ps1 | iex

If shims fail to run, allow local scripts for your user:

Set-ExecutionPolicy -Scope CurrentUser RemoteSigned

From the repo root:

proto use    # installs the tools pinned in .prototools

moon run web:dev       # localhost:5173
moon run api:dev       # localhost:8787
moon run desktop:dev   # see apps/desktop/README.md

We're not set up to take outside contributions yet while the architecture is being designed. If you want to follow along, ask questions, or just hang out, join the Discord or open an issue.

OpenCut is supported by companies that believe in open source creator tools.

• fal.ai: Generative image, video, and audio models all in one place.
