Umber is a desktop app for generating AI images and videos. It puts twelve providers behind one interface: you bring your own API keys, calls go straight from your machine to the provider and everything you generate stays on disk. There is no Umber account, no server in the middle and no subscription.
Works with Google, OpenAI, Black Forest Labs, ByteDance, Kling, Alibaba, Runway, Ideogram, Recraft, MiniMax, xAI and Reve.

| Platform | Asset |
|---|---|

| Windows | Umber-<version>-x64.exe |

macOS. Signed and notarized. Drag Umber to Applications and open it.
Windows. Not signed yet, so SmartScreen shows "Windows protected your PC" on first run. Choose More info, then Run anyway. The UAC prompt names an unknown publisher for the same reason.
Linux. Mark the AppImage executable and run it:
chmod +x Umber-*.AppImage && ./Umber-*.AppImageThe app checks for new releases on launch and tells you in settings when one is available.
- Your keys. Add API keys for the providers you use. They are encrypted with your OS keychain and never leave your machine except to call the provider itself.
- Your disk. Every image and video you generate is saved locally. Nothing is uploaded anywhere else.
- One interface. Pick a model, write a prompt and generate. Switching providers does not mean switching apps.
You pay the providers directly for what you generate. Umber itself is free and MIT licensed.
You need Node 24 and pnpm 11 (corepack enable).
