Workbench Launcher

A regular Workbench launcher: pick an install, start or stop the daemon, open Workbench. The extra is Keystone dark mode — three themes — and a new loading splash.

What it does

It finds the Workbench installs on the PC. You pick one, pick a theme, and launch. Start and stop the Windows Niagara service from the pad. Host ID is there if you need it for a license.

Launch WB drops the signed theme jars into that install’s modules folder and starts Workbench with the theme you picked.

Three dark themes

Keystone — our icons (Lucide plus an original fox).
Keystone Lucid — the same dark chrome with Lucid icons.
Keystone Zebra — the same dark chrome with the install’s Zebra icons.

Niagara 4.7 through 4.15. Stock Lucid and Zebra stay in the dropdown if you want them back.

Niagara does not make a thorough dark mode easy. We went as far as the theme system lets us, and we are still working on it. If something is really in the way, let us know.

Loading splash

Launch WB can put a Keystone loading splash in that install’s etc folder. Writing there needs administrator once. If the splash is already ours, we leave it alone. If Windows blocks the copy, you can restart as administrator or skip it — Workbench still opens. There is a “Don’t show this again” checkbox.

How to use it

Download the setup from Downloads.
Run the installer and accept the launcher license.
Pick a Workbench install and a theme.
Launch WB. Restart as administrator only if you want the splash copied in.
