ComfyUI-Enhancement-Utils is a new custom node package that brings essential utility features to ComfyUI with full support for nested subgraphs. The toolkit includes resource monitoring, execution profiling, graph auto-arrangement, and node navigation tools in a single unified package.

Developer phazei created this collection after noticing that existing community packages scattered these features across multiple extensions, many of which were aging or bloated. The main issue was that none of the alternatives supported subgraphs properly—profiling badges would disappear inside them, and graph arrangement only worked at the root level.

Core node features included

  • Resource Monitor displays real-time CPU, RAM, GPU, VRAM, temperature, and disk usage directly in the menu bar with NVIDIA GPU support.
  • Node Profiler shows execution time badges on every node with live timers that persist when navigating between subgraphs.
  • Node Navigation adds right-click options to jump to any node or auto-pan the canvas to track the currently running node.
  • Graph Arrange provides multiple layout algorithms including Quick, Smart (dagre), and Advanced (ELK) for organizing workflows.
  • Utility Nodes include Play Sound, System Notification, and an enhanced Load Image loader with recursive subfolder scanning.

Users working with complex workflows that rely heavily on subgraphs will find these tools particularly useful for debugging and organization. The profiler's ability to show aggregated timing data for nested containers helps identify performance bottlenecks that would otherwise remain hidden.

The developer's approach

The developer rewrote every feature from scratch on the V3 API rather than patching existing solutions. This approach ensures each tool works correctly at any nesting depth. Unlike existing profiler packages that store timing data directly on node objects—causing data loss when switching graphs—this implementation persists information properly.

'This is a focused package — I'm not trying to add everything under the sun, just the base utilities that ComfyUI should arguably ship with,'

the developer stated. The package is MIT licensed and designed to complement rather than conflict with other extensions.
