OpenCut Classic is the working editor. Open it in your browser at opencut.app →.

The original Classic code remains available in its archived repository.

Build next

This branch is the new foundation:

• Web — a React workspace with a placeholder home page and /editor route.
• API — a Cloudflare Worker with status, health, and echo endpoints.
• Desktop — a GPUI shell with browser, preview, inspector, and timeline panels.

The Editor API, plugin architecture, shared Rust core, mobile app, MCP server, headless rendering, and in-editor scripting are the direction—not shipped editor features.

Quick start

Install proto, then start the web workspace with the repository's pinned toolchain:

Install proto

Linux, macOS, or WSL

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

Windows PowerShell

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

If proto's shims are blocked, run Set-ExecutionPolicy -Scope CurrentUser RemoteSigned.

proto use
moon run web:dev

Open http://localhost:5173. The /editor route currently reads “Coming soon.”

API and desktop workspaces

moon run api:dev       # http://localhost:8787
moon run desktop:dev   # early native editor shell

Desktop platform requirements are documented in apps/desktop/README.md.
