QLab on Windows?

QLab is Mac-only, so there's no official QLab for Windows. ZasCue covers the essentials for live audio and image/title projection. See the full QLab vs ZasCue comparison.

Is ZasCue useful to you?

It's free and ad-free, and it always will be. If you'd like to see it keep growing, chipping in whatever you want helps enormously.

Support the project

Something broken? An idea?

ZasCue is built by one person, and most of what it does today came from users asking for it. If something doesn't work or you're missing a feature, tell me here — I read every message and reply personally.

Guides

How to open it on Windows

Download ZasCue.exe and double-click it. The first time, Windows may show a blue "Windows protected your PC" notice — click "More info" then "Run anyway". That's normal for free, unsigned apps; it doesn't mean it's unsafe.

Updating to a new version

Nothing to uninstall. Download ZasCue.exe again and replace the old file — delete it first, or Windows keeps the new one as ZasCue (1).exe and you may keep opening the old version by mistake. Your shows are untouched. The version you’re running shows at the very top, next to “ZasCue”. If you have a taskbar or desktop shortcut, point it at the new file.
