FAQ

Questions

How much does it cost?

The app is free. You pay fal.ai or WaveSpeed for what you generate, from a few cents for an image to about a dollar for a video. SimpleNode shows the price before every run.

Do I need a fal.ai account?

No. A WaveSpeed key runs most of the models. A few models and tools only exist on fal.ai, and the app marks them "fal only".

Which Macs does it run on?

Every Mac with an Apple silicon chip (M1 and later) or an Intel chip, on macOS 11 or later. The same download works on both.

macOS blocks the app on first launch

Open System Settings → Privacy & Security, then click Open Anyway. If macOS says the app "is damaged", run xattr -dr com.apple.quarantine /Applications/SimpleNode.app in Terminal.

Can I be billed twice for the same result?

No. "Run all" skips the nodes that already have a result. To redo one, run that node on its own.

Where are my files and keys stored?

On your Mac only. Results are downloaded as soon as they're ready, because the providers' links expire.

What does the Compositor need?

ffmpeg, installed once with Homebrew: brew install ffmpeg. The rest of the app works without it.

Does it work with Claude?

Yes. Turn on the MCP server in Settings → MCP, and Claude Code can build and run workflows on your canvas, within the spending cap you set.

How do I update the app?

Download the latest version from this page and drag it into Applications again. Your projects and keys are kept.

Is there a Windows version?

Not yet. SimpleNode is for macOS only.
