Windmill FAQ
- Do I need to install anything or write code to use Windmill?
- No install needed — it runs in the browser.
- Does Windmill work on a phone?
- No. It needs a computer.
- Can I use Windmill commercially?
- The licence is AGPL-3.0. Using it commercially is fine, but if you distribute something built on it you may be required to release that under the same licence. Keep it internal, or check before distributing.
