ComfyUI spaghetti management, now with subgraph support

What it does

KJNodes is a miscellaneous collection of utility, optimization, and quality-of-life custom nodes for ComfyUI. The README is admirably honest: “pretty random collection” with documentation “mostly in the node descriptions and tooltips.” The standout feature is a recently rewritten Set/Get system for routing data between nodes without direct wire connections.

The interesting bit

The March 2026 Set/Get rewrite treats ComfyUI’s graph as a scope hierarchy rather than a flat canvas. A Set node in a parent graph becomes visible to all child subgraphs, with Gets searching upward through ancestors. This is the rare visual-programming feature that acknowledges that real workflows grow hierarchical and messy, not just wide.

Key highlights

• Bidirectional conversion: right-click any link midpoint to Set/Get-ify it, or right-click a Set/Get pair to restore direct wires
• Batch operations: convert all outputs of selected nodes at once, or nuke every Set/Get pair back to links via settings
• Keyboard-heavy workflow: Ctrl+Shift+S/G/L for adding Sets, Gets, and toggling link visibility
• Shift+middle-click slot interaction creates connected Set or Get nodes without menu diving
• Type inference and color-coding from downstream connections, plus double-click to jump from Get to its paired Set
• JS extensions for node insert (hotkey D) and swap (hotkey S), plus a “shake to disconnect” option

Caveats

• The author notes the collection is “pretty random” and documentation is thin; you’ll be reading tooltips
• Backwards compatibility claim is qualified with “as far as I’m aware currently”

Verdict

Worth a look if your ComfyUI workflows have outgrown flat canvas management and you’re already using subgraphs. Skip if you want a focused, well-documented node pack with clear boundaries — this is a kitchen-sink repo that happens to contain a sophisticated routing system.
