Cut, paste, roast in your browser

Professional video editing, right in the browser with WebGPU and WASM

No-install video editor drops as Safari stutters and Microsoft gets roasted

TLDR: A free, open-source pro-style video editor now runs entirely in your browser with real-time effects and local files. Commenters are excited but split: some see Safari stutters and doubt it’ll replace big pro tools, others love it as a drop‑in editor and want collaboration—plus plenty of Microsoft/Clipchamp shade.

Video editors, meet your new tab. Tooscut is a free, open-source non-linear editor (aka pro-style video editor) that runs right in your browser, using new web tech to tap your graphics card for real-time previews and effects. No install, and your files stay on your machine. The dev dropped the source and commenters showed up with confetti—and stopwatches.

Top drama: a Safari user on an M2 Air reported playback “very, very choppy,” triggering the classic Apple-vs-web skirmish. Some shrugged it off as early days; others joked Safari is where smooth frames go to buffer. Meanwhile, a pragmatist chimed in: this won’t replace the giant pro suites just yet, but it’s perfect to embed into web apps that already handle video—cue devs dreaming of drag-and-drop editors in every site.

Then came the spice: memories of Clipchamp, the web editor Microsoft bought, now “enshittified” according to one roast that had the room howling. The counter-move wishlist? Shared assets and collaborative projects—think Google Docs for video, without sending your footage to the cloud. If Tooscut nails smooth playback and collab, the browser might just steal the cutting room.

Key Points

  • Tooscut Editor is a browser-based non-linear video editor requiring no installation.
  • It uses WebGPU and Rust/WASM for GPU-accelerated compositing and near-native performance in previews and exports.
  • The multi-track timeline supports unlimited video/audio tracks, linked clips, and cross-transitions.
  • Keyframe animation with bezier easing curves is supported for transforms, opacity, and effects.
  • Real-time GPU-computed effects (brightness, contrast, saturation, blur, hue rotation) are available, and media stays local via the File System Access API.
