Add video editing to any app you build.
The open-source video editing SDK for React, React Native and Flutter. Trim, split, add audio and export MP4 right on the device.

One toolkit for building video editors
One project format and one command model. Each platform renders with its own native media engine.
@cutiva/react-native
React Native
The same TypeScript core on a native engine built with AVFoundation and Media3, shipped as an Expo Module.
cutiva_flutter
Flutter
A federated plugin over the same native engine, with the same API shape in Dart for iOS and Android.
Ship video features in days, not months
Edits stay on the device
Preview and export run on the device's hardware encoders. No render servers to pay for, and your users' videos never leave their phone or browser.
One portable project format
A versioned JSON schema with integer timings. Save on the web, open in React Native or Flutter.
Undo and redo, built in
Every edit is a command the core validates and records. Nothing is ever left half applied.
Headless or drop-in UI
Use the timeline component, or build your own interface on the core.
Import, edit, export
Import
Load local video and audio. Cutiva reads duration and codecs, and fingerprints each file so projects relink anywhere.
engine.importFile(file)Edit
Trim, split, reorder and mix audio with commands, from your UI, from ours, or from code.
editor.dispatch(command)Export
Render an MP4 on the device with progress and cancel, or save the project as JSON to keep editing later.
engine.export({ container: "mp4" })
Free forever
Open source SDK

Frequently asked questions
Can I use Cutiva today?
Not in production yet. The core works and is tested; the browser engine is being verified. Join the waitlist or watch the repo to know when v0.1 lands.
Is it really free?
Yes. The SDK, the editor components and local export are open source under Apache-2.0. Only the optional cloud features will be paid.
Do I need a server to export video?
No. Export runs on the user's device with the hardware encoders of the browser or operating system.
Which platforms are supported?
The pilot covers React web, React Native and Flutter. Native Swift and Kotlin SDKs and desktop come later, on the public roadmap.
How can I contribute?
Star and watch the repo. Issues labelled good first issue open as the core settles. Read CONTRIBUTING.md before your first pull request.
