OpenCut: The Open Source CapCut Alternative With 97,511 Stars

OpenCut is a free, open source video editor that runs in your browser, processes your footage locally, and exports without a watermark or a subscription. It has 97,511 stars on GitHub as of November 7, 2026, which makes it one of the most starred open source video editors ever built. There is one twist you should know before you open it: the editor you can use today is the classic version, while the main project is being rewritten from the ground up.

Key Takeaways

• OpenCut is a free video editor under the MIT license, with 97,511 stars and 9,713 forks on GitHub as of November 7, 2026.

• The classic editor at opencut.app works today: trim, text, captions, music, and watermark-free MP4 export, all processed locally in your browser.

• The project is being rewritten from scratch around a Rust core, with a plugin-first architecture, an MCP server for AI agents, headless automation, and a scripting tab.

• The rewrite is still scaffold-level, with no working timeline yet, so the classic build is the one to use right now.

• OpenCut took off fast: it launched in June 2025 and hit the Hacker News front page three weeks later with 443 points.

The Problem It Solves

CapCut is the default video editor for a generation of creators, and it is very good at what it does. It is also freemium, cloud-based, and proprietary. The free tier puts key features behind a paywall, your footage travels to someone else's servers, and your projects live inside a format only CapCut understands. For creators who edit every day, that trade starts to feel expensive in more ways than one.

OpenCut takes the opposite approach. It is open source under the MIT license, so anyone can inspect the code, run it themselves, or build on it. It processes video locally in your browser, so your footage stays on your machine. And it exports without a watermark, which is the first thing most people check when they try a free editor.

That combination explains the star count. OpenCut launched on June 22, 2025, and about three weeks later it reached the Hacker News front page with 443 points. By July 16, 2026 it had 72,669 stars, and by November 6, 2026 it had grown to 97,506, a gain of 18,049 stars in 101 days. (GitHub, Hacker News, Hysen Labs)

What You Can Use Today: The Classic Editor

The usable editor right now is the classic version, which runs at opencut.app and lives in the archived opencut-classic repository. It shipped three releases in its first two months: v0.1.0 on February 23, 2026, v0.2.0 on March 2 with keyframes, blur, and ripple editing, and v0.3.0 on April 15 with masks, a graph keyframe editor, volume and speed controls, stickers, and a Rust and wgpu WASM compositor.

A hands-on test in October 2026 put the classic editor through a real edit on a MacBook Pro M1 in Chrome: create a project, trim a clip, add text, generate auto-captions, add music, and export. The captions run on a Whisper model downloaded in the browser, which takes 20 to 30 seconds, and then everything works offline. A 7.5 second vertical video exported as 1080x1920 MP4 at 30 frames per second in about 2.5 seconds, with no watermark and no outro added. During editing, the largest network transfer was 821 bytes while the video itself was about 2 MB, which confirms the local-processing claim. (leesugano.com)

That same test also found the rough edges. The editor is desktop only for now, the Transitions panel shows "coming soon", Blur is the only effect, and there are no templates or AI features beyond captions. It is a capable, honest editor, not a finished CapCut clone.

The Rewrite: What Is Coming

The OpenCut team is rebuilding the editor from scratch, and the plan is ambitious. The new version is built around a Rust core with GPU-accelerated compositing, a TypeScript and Next.js web frontend, and a desktop app built with GPUI. On top of that core, the roadmap promises an Editor API, first-class third-party plugins through a plugin-first architecture, an MCP server so AI agents can edit your timeline, headless mode for automation and batch rendering, and a scripting tab directly inside the editor. (GitHub, DEV Community)

That roadmap is exactly what makes OpenCut interesting beyond a free editor. A headless, scriptable video editor with an MCP server is a tool developers can build pipelines around: render a hundred short clips from a template, let an agent cut a rough timeline, automate the boring parts of a weekly video. No mainstream editor offers that combination today.

Be clear-eyed about the timeline, though. A teardown in October 2026 cloned the rewrite at its pinned commit and found only 130 tracked files and about 10,498 lines of non-lockfile code, 64 percent of it UI primitives, with no timeline, renderer, or plugin host yet. The editor page renders "Coming soon." The last push to the main branch was September 24, 2026, and outside contributions are paused while the architecture is designed. The rewrite is a promise, not a product, and the classic build is what you should actually use. (ai.thesatyajit.com)

OpenCut at a Glance

OpenCut vs CapCut

Who Should Try It

OpenCut fits creators who want a free editor without lock-in: short-form video makers, open source enthusiasts, and anyone who would rather keep footage on their own machine than upload it to a cloud. It also fits developers who care about the rewrite, because a scriptable, headless editor with MCP support could become infrastructure for automated video work.

It is less suited to editors who need a finished, polished tool today. If you need transitions, effects, templates, and a mobile app right now, CapCut or another established editor is still the practical choice. OpenCut classic covers the basics well, and the rewrite is the reason to watch the project, not the reason to switch today.

Try this first: open opencut.app, cut a short clip, add captions, and export it. Then check the rewrite repository to see where the project is heading. That is the honest shape of OpenCut in November 2026: a working free editor today, and a much bigger idea being built behind it.

OpenCut on GitHub

This is also a good example of what open source means in practice: a tool built in the open, under a permissive license, that anyone can inspect, use, and build on. Open source creative tools are having a moment, from PhotoCraft, the open source Photoshop alternative rebuilt in Rust, to video editing with OpenCut.

FAQ

Is OpenCut really free?

Yes. It is open source under the MIT license, so you can use it in personal and commercial projects without paying.

Does OpenCut add a watermark?

No. Exports from the classic editor carry no watermark and no added outro.

Can I use OpenCut on my phone?

Not yet. The classic editor is desktop only for now, and mobile support is part of the rewrite plan.

What is the difference between OpenCut and OpenCut Classic?

OpenCut is the main repository, currently being rewritten from scratch. OpenCut Classic is the archived repository with the working editor that runs at opencut.app today.

Can AI agents edit video with OpenCut?

That is the plan. The rewrite roadmap includes an MCP server so AI agents can edit timelines directly, plus headless mode and a scripting tab. None of these are shipped yet.
