A ComfyUI companion that suggests core / available equivalents for custom
nodes and replaces them in a workflow.
- Backend (utfcn_core.py, __init__.py): read-only /utfcn/scan analysis that
ranks equivalents in three tiers (curated → exact-signature → partial
heuristic) from the live node registry.
- Frontend (web/utfcn.js): on-add mode (Off / Suggest / Force auto-replace),
bulk "Replace with core / available…" command + Extensions menu with a
preview-then-confirm dialog, and a right-click single-node replace. The swap
engine only rewires losslessly.
- mappings.json: 7 hand-verified curated rules mined from installed packs
(essentials, KJNodes, WAS); user_mappings.json for user overrides.
- Docs + branding: README, icon and social banner (SVG + PNG), GPL-3.0.
