OpenCut Browser Video Editor
Productivity Tools
OpenCut (https://opencut.app/) is an open-source, cross-platform video editor designed to be a free alternative to CapCut (the international version of 剪映). The project was started by a group of developers dissatisfied with CapCut's charging policies and promises a watermark-free, no-subscription, locally processed, completely free video editing experience.
核心特点
隐私优先:所有视频编辑操作均在用户设备本地完成,视频数据不会上传到云端,确保用户隐私安全。
完全免费:OpenCut不收取任何费用,没有"高级版"或"会员功能",所有功能一律开放,无需登录和订阅。
开源可自托管:采用MIT许可证,任何人都可以fork、修改和部署自己的实例,支持私有部署或集成到自己的平台中。
跨平台支持:基于Web技术构建,支持Windows、macOS和Linux系统,打开浏览器即可使用。

发展现状
As of March 2026, OpenCut has over 46.7k stars on GitHub, 92 contributors, and an active community. The project is currently in Beta: core features like the timeline editor, multitrack support, and real-time preview are mostly complete, but advanced effects, a keyframe system, and complex filters are still under development.
The project is sponsored by companies such as Vercel and fal.ai, and is fully open-source, allowing users to freely modify and redistribute it. For users who prioritize privacy and want full control over their creative tools, OpenCut offers an appealing free option.
