Or just tell the agent what you want and watch it edit.

Frontstage editing a project with an AI-generated clip selected

_{That palm tree? Generated inside the editor, straight onto the timeline.}

What it does


🎬 Real timeline editing	Multi-track, ripple & razor tools, linked A/V, sync-locked tracks, keyframes on opacity/position/scale/crop/volume, snapping, frame-accurate trims
🎨 Color & effects	21 GPU effects: color wheels, curves & hue curves with histogram, LUTs (.cube), chroma key, invert, blur/grain/glow, 16 blend modes
✨ AI generation	Video, image, audio & TTS via fal.ai — Veo, Kling, Seedance, nano-banana and more. Your key, your cost control, results land in the library
🤖 The agent	A chat that edits your timeline: cuts, layouts, color, captions — 40+ tools over the same undo stack you use. Any model via OpenRouter
💬 Captions & transcription	On-device Whisper transcription (free, no key), word-level editing, 11 animated caption presets, SRT/VTT import and export, remove filler words by text
🔍 Visual search	Search your footage by what's in it — on-device SigLIP embeddings, no cloud
🔌 MCP server	Point Claude (or any MCP client) at your project — 51 tools to edit it from the outside
📤 Pro interop	Export FCPXML (DaVinci Resolve / Final Cut), XMEML (Premiere), import/export SRT/VTT subtitles, MP4 render

Run it

Web — frontstage.studio: the full editor in your browser, no account, no keys needed for editing
Windows — download the installer (unsigned: SmartScreen will warn — "More info → Run anyway")
macOS / Linux — use the web editor (no install, full functionality)

From source (Node 18+, pnpm 10):

pnpm install
pnpm -F @frontstage/desktop dev     # desktop app
pnpm -F @frontstage/web dev         # web app

Your keys, your data

AI features are strictly bring-your-own-key: fal.ai for generation, OpenRouter for the agent.
Keys live in your OS keychain (desktop) or your browser (web) — never on anyone's server.
Transcription and visual search run entirely on your machine, free. Zero telemetry.

Let Claude edit your project (MCP)

The desktop app ships an MCP server (Settings → Agent → enable). Add it to Claude Code / Claude Desktop:

{
  "mcpServers": {
    "frontstage": {
      "type": "http",
      "url": "http://127.0.0.1:19789/mcp",
      "headers": { "Authorization": "Bearer <token from Settings>" }
    }
  }
}

Then: "split the interview at every silence and add captions" — and watch your timeline change. 51 tools: editing, color, generation, transcription, export.

Under the hood

pnpm + Turborepo monorepo — TypeScript end to end:

Package	What it is
`packages/core`	Headless domain: timeline model, commands/undo, ripple engine, color math, captions, interop exporters — zero UI deps, 1000+ tests
`packages/engine`	Browser playback & render: WebGPU compositor (21 effects, 15 blends), WebCodecs decode, WebAudio mixing, MP4 export
`packages/ui`	The React editor — one `<Editor>` shared by web and desktop, token-driven design system
`packages/ai`	Agent loop, 48-tool MCP catalog, fal.ai generation pipeline, on-device Whisper & SigLIP
`apps/desktop`	Electron shell: native FS, keychain, ffmpeg, the MCP server
`apps/web`	The same editor on File System Access API
`apps/proxy`	Self-host relay for web AI (your server, your keys)
