OpenCut

Open source · OSI-approvedStatus: unknown

Video editor that runs entirely in the browser

OpenCut is a timeline video editor that installs nothing and uploads nothing. Media stays in the browser, processing happens locally through WebCodecs, and there is no account step before you can cut a clip.

It will not replace a professional non-linear editor, but for trimming, captioning, and assembling short pieces it removes the entire setup step.

Decisive facts

Multi-track timeline with trimming, splitting, and transitions
Local processing in the browser, no upload required
No account needed to start editing
Text, captions, and basic colour adjustment
Export to MP4 directly from the browser

Ente stores photos and videos encrypted on the client, so the server holds ciphertext it cannot read. Sync, albums, and sharing all work on top of that constraint rather than around it.

LicenseAGPL-3.0

Cap records screen and camera, then gives you an editor with backgrounds, automatic zooms, and cursor smoothing before you share a link. It is built in Rust on Tauri, so the binary is small and recording does not tax the machine it is recording.
