Loved in the wild

“I rebuilt a prompt I’d iterated on for years in one evening. The gradient engine alone sold my whole team.”
Rivers OkaforPlatform Engineer, Kite Systems
“The fish config it generated was cleaner than anything I’d hand-written. It just works, on every machine I touch.”

Questions, answered

Which shells does FUSE support?

zsh, bash, fish, PowerShell (5.1 and 7+) and any starship-compatible terminal. Exports are plain text, so exotic setups work too.

How do I install an exported theme?

Paste the one-line command from the export panel into your terminal. FUSE writes your config file and reloads the prompt immediately.

Who owns the themes I create?

You do. Themes are yours to sell, share or keep private. FUSE claims no rights over your work.

Does FUSE work with PowerShell?

Yes. The studio renders a faithful PowerShell preview and exports a profile script compatible with Windows Terminal, pwsh 7+ and PSReadLine.

What are the free plan limits?

Spark includes one saved theme and community exports. There is no time limit and no credit card required.
