Ultimate Lora Loader (Civitai)

Specialized ComfyUI LoRA stack loader based on Ultimate Lora Loader.

This is not an upstream contribution / PR track — it’s a separate, narrowly focused product: the original folder-browser LoRA stack, plus Civitai-aware naming, cover previews, dual info buttons, and a tighter Add Lora browser. Bug reports and feature requests go here, not to the original repo.

Bug reports: github.com/StoneZol/…/issues

Everything from the base node still works (folder browser, optional CLIP, drag-to-reorder, split strengths, missing-file detection, …). This build adds extras on top:

1. Two per-row info buttons
   • ? — Civitai Toolkit local DB popup (gallery-style: name, tags, triggers from indexed scan)
   • i — ComfyUI-Custom-Scripts View Lora info dialog (the same one as RMB on a default LoraLoader: preview images, Civitai link, trained words, …)
2. Civitai dual naming + cover preview + base model — when Toolkit has the LoRA indexed: Civitai title + filename; hover image icon for cover; Base column in Add Lora; on stack rows hover name → base model tooltip only
3. Add Lora browser UX — sticky search (~¾ width, always visible while scrolling), autofocus on open, filter in the current folder (filename / folder / Civitai name / base model), Tab stays inside the popup (Esc closes)

Tested with Civitai Toolkit 4.1.3 and ComfyUI-Custom-Scripts 1.2.5.

What this build adds

Feature	Behavior
? on each row	Soft dependency on Civitai Toolkit. Opens Toolkit’s local-index info popup.
i on each row	Soft dependency on ComfyUI-Custom-Scripts (pysssss). Opens the full View Lora info dialog (preview / Civitai link / keywords).
Dual name	Toolkit-indexed LoRAs show Civitai title (top) + filename (bottom) on stack rows and in Add Lora. Without Toolkit / not indexed → filename only.
Base model	Add Lora: separate Base column. Stack rows: hover name → base_model tooltip only (no path/name duplicate).
Cover preview	Image icon before the name; hover shows Toolkit cover (stack rows + Add Lora list). Dimmed when no cover.
Filter in Add Lora	Filters the current folder only (filename / subfolder / Civitai title / base model). Cleared on drill-down / breadcrumb.
Sticky search + autofocus	Search bar pinned (~¾ popup width) while the list scrolls; focused when the popup opens or you change folder.
Keyboard in popup	Tab / Shift+Tab cycle inside the popup (search → list → breadcrumbs). Enter / Space open/select. Esc closes.

For base-node behavior (install notes, CLIP optional, missing-file UX, etc.) see the original README.

Requirements

The loader node itself runs standalone. Dual naming / cover preview enrich from Toolkit when present (soft). For the info buttons you also need:

Button	Plugin	Tested version	Repo
? (+ names / covers)	Civitai Toolkit	4.1.3	BAIKEMARK/ComfyUI-Civitai-Toolkit
i	ComfyUI-Custom-Scripts (pysssss)	1.2.5	pythongosssss/ComfyUI-Custom-Scripts

Install both into ComfyUI/custom_nodes if you want the full experience. Without Custom Scripts, i will fail with an alert; without Toolkit, ? / dual names / covers degrade gracefully (filename-only, no cover).

Install

cd ComfyUI/custom_nodes
git clone https://github.com/StoneZol/comfyui-ultimate-lora-loader-civitai-toolkit-supported.git

# also needed for the info buttons / Civitai names & covers:
git clone https://github.com/BAIKEMARK/ComfyUI-Civitai-Toolkit.git
git clone https://github.com/pythongosssss/ComfyUI-Custom-Scripts.git

Or copy this folder into ComfyUI/custom_nodes/ and fully restart ComfyUI.

Don’t install two copies with the same js/ullc/config.json ids — duplicate API routes will crash startup. Keeping the original Ultimate Lora Loader next to this one is fine.

Multiple copies side-by-side

Edit js/ullc/config.json in each copy so these fields are unique:

Field	What it controls
extension_name	frontend registerExtension id
node_class	Comfy node type id (workflows)
node_display_name	name in the Add Node menu
api_prefix	backend route, e.g. /ultimate_lora_loader_civitai → .../tree
style_id	CSS <style> element id
log_prefix	console / server log tag

Example second copy: change node_class to UltimateLoraLoaderCivitaiB, api_prefix to /ultimate_lora_loader_civitai_b, and the other fields accordingly. Then fully restart ComfyUI.

Default menu name: Ultimate Lora Loader (Civitai) (loaders).

Usage

1. Add Ultimate Lora Loader (Civitai) to the canvas.
2. Wire model (and optionally clip).
3. Add Lora → type to filter the current folder (search is focused and stays visible while scrolling) → Tab through results → Enter to pick / open a folder. Esc closes.
4. On each stack row: hover the image icon for cover; click ? for Toolkit local info, or i for the full View Lora info dialog.
