An open-source CapCut alternative video editor is being rebuilt from scratch as a plugin-friendly, multi-platform tool

OpenCut is a free, open-source video editor meant to be an alternative to CapCut. The project has 87,133 GitHub stars and is currently undergoing a full rewrite to support web, desktop, and mobile from one codebase. During this rewrite, outside code contributions are paused, but the older 'classic' version is still usable today.

What it does

  1. What: OpenCut is a free and open source video editor for web, desktop, and mobile, positioned as an alternative to the popular app CapCut.
  2. How: The team is rewriting the entire project from the ground up using a Rust core so the same codebase can power web, desktop, and mobile versions, with a plugin-first architecture, an Editor API, and even an MCP server for AI agents.
  3. Result: The new rewritten version will live at new.opencut.app once ready, while the current working version (opencut-classic) remains available at opencut.app; the project uses tools like proto and moon for local development.
  4. Status: External contributions are not accepted yet since the architecture is still being designed, but people can follow progress via Discord or GitHub issues.
  5. Support: The project is sponsored by fal.ai, a generative AI media platform, with the project licensed under MIT.

Why it matters

For creators and developers looking for a free, self-hostable alternative to commercial video editors like CapCut, OpenCut's move to a plugin-based, cross-platform architecture with AI-agent support (via MCP) signals a more extensible and automatable editing tool. Its large community (87k+ stars) also makes it a notable open-source project to watch in the creator-tools space.
