VarBoard Bool

Booleans are the variable type everybody forgets about, and they're the most satisfying thing on a control panel. VB_Bool is a true/false switch that surfaces on the VarBoard panel - a checkbox, essentially - so you can flip a workflow behavior on and off without opening a node you buried three groups deep.

What it does

Same pattern as the rest of the pack: the backend is a pass-through that returns (value, label) unchanged, and the frontend renders it as a toggle on the floating panel anchored by VB_Panel. Click the switch on the board, it writes back into the node's widget, and the next run sends the new boolean down the wire.

Inputs:

• value - the boolean. Default false, toggled from the board.
• label - what the row is called on the panel. Default "Boolean".

Outputs: BOOL (the boolean value) and LABEL (the label string).

What to wire it into

Anything that takes a real BOOLEAN input. A growing number of utility and control packs expose toggles - enable/disable a pass, flip a branch in an if/switch node, gate a section of the graph. A VB_Bool on the panel is a far nicer way to flip those than hunting for the checkbox inside a stacked widget.

One compatibility note, because it trips people up: ComfyUI's BOOLEAN widget type is comparatively recent, and plenty of older nodes still expect an INT 0/1 instead. If the target input's type is INT, a VB_Bool output won't plug in cleanly - check the input type before you wire, or feed it through a small int conversion node. When the target genuinely takes BOOLEAN, this is a one-to-one drop-in.

Install

Same as every node in this pack - zero Python dependencies, zero model downloads. ComfyUI Manager (search "VarBoard"), or:

cd ComfyUI/custom_nodes
git clone https://github.com/IA-gyz/comfyui-VarBoard

Restart ComfyUI and hard-refresh your browser. Drop a VB_Panel on the canvas and any VB_Bool you add will register itself on the board automatically.

The honest take

A boolean row is a small thing, but it's the clearest example of what this pack is actually good at: taking a parameter you'd otherwise squint at somewhere in the graph and making it something you flip without thinking. If your workflow has an "I always forget to turn this off before a big batch" switch, putting it on the board is genuinely the fix.
