Frequently asked questions

Are these design tools really free?

Can I use the generated code on commercial projects?

Yes. All generated CSS, HTML and palettes are yours to use anywhere, including client work.

Is any of my data uploaded?

No. Everything runs locally in your browser; nothing is sent to a server.
