Free, open-source Premiere-style video editor that runs in your browser, with a JSON timeline that AI agents can edit live.
About FableCut
FableCut is a free, open-source non-linear video editor in the style of Premiere Pro that runs in the browser. It has Source and Program monitors, multiple video and audio tracks with trim, split, snap, ripple delete, lift and extract, keyframes, masks, filter presets, an audio mixer and color tools, proxies for 4K, HEVC and ProRes footage, and export presets for YouTube, Shorts, Reels, TikTok and X. The whole timeline is one project.json file, so you can edit by hand or let an AI agent such as Claude Code, Codex or any MCP client change the cut while the UI updates live. Runs in the browser: a free hosted Studio (Chromium-based browsers only, no account) or a local install with Node.js 18+. The hosted Studio works on a folder on your own disk and never uploads your clips. AI agents can optionally edit the timeline via MCP; no AI key is needed for manual editing. The hosted Studio exports H.264 MP4 only. Frequent releases (v1.16.0 on 20 Oct 2026). Licensed MIT.
