✅ Boolean Input

A boolean input that outputs a BOOLEAN. That's the whole node. It exists because of the pack's web-interface integration: ComfyUI's built-in primitives don't carry a name for a frontend to render a labeled form field against, and this one does. In the default desktop UI it's just a checkbox you can drag anywhere; in the pack's hosted/API frontend, the name field becomes the label of a real form control that sets this value.

Inputs: name (default bool_input - the identifier the web interface uses) and value (the boolean, default false). One output: BOOLEAN, carrying exactly the value you set. There is no computation, no state, no side effect. It's a wire-to-a-constant.

Where it fits

These named input nodes (String, Int, Float, and this one) are a family designed for one scenario: a ComfyUI workflow exposed through a web form or API where the end user shouldn't see the graph - they just flip "Enable upscale" and the graph runs. If you're building that kind of hosted setup, this is how you surface a toggle cleanly. If you're a desktop user, the built-in primitive node does the same job and you'll never touch this one.

Installation

It's part of ComfyUI-ArchAi3d-Qwen. ComfyUI Manager ("ArchAi3d Qwen") or:

cd ComfyUI/custom_nodes/
git clone https://github.com/amir84ferdos/ComfyUI-ArchAi3d-Qwen.git
cd ComfyUI-ArchAi3d-Qwen
pip install -r requirements.txt

Restart, look under ArchAi3d/Inputs. Free personal use, paid commercial license (the pack's usual dual-license deal).

Where people get burned

Honestly, the main trap is expecting more. It outputs a bare BOOLEAN, which most of ComfyUI's node inputs (especially older ones) aren't typed to accept directly - they want an INT 0/1. If a node won't accept the wire, check its input type: BOOLEAN ≠ INT, and you may need a small converter node between them. And because the pack registers a whole family of these named inputs, don't confuse name (the frontend label) with value (the data) - renaming doesn't change what's output. If you just want a checkbox that outputs 0/1 into an INT input, the stock primitives are the smoother path.
