ComfyUI-LoraSlider-LM

A self-contained LoRA Slider node for ComfyUI that is designed to sit alongside ComfyUI-Lora-Manager (LM) and reuse its rich metadata — without modifying LM in any way.

It brings the slider UX of ComfyUI-Flex-Pack into the LM ecosystem, while fixing Flex's biggest pain point: adding and configuring sliders one at a time.

What it does

• One bipolar strength slider per LoRA, with editable min/max bounds and semantic end-labels — e.g. label the low end "skinny" and the high end "obese". The slider shows the actual strength value (not a 0–100 %).
• Batch-add many LoRAs at once, three ways:
  1. + Add LoRAs — a searchable multi-select picker backed by LM's library. Search by name or path: include a / (e.g. turbo/slider) to match folders.
  2. + Text — type names or paste <lora:folder/name:0.8> codes (e.g. copied from the LoRA Manager UI); each becomes a slider.
  3. Import from Pool — connect LM's Lora Pool node and pull in every LoRA matched by its folder/tag filters.
• Set values manually (drag the slider or type a number), or randomize:
  • per-slider 🎲, or 🎲 Strength (all unlocked) — re-roll strengths in range;
  • 🎲 Enabled — randomly enable/disable each unlocked slider;
  • randomize each run toggles — re-roll strength and/or enabled state on every queued run (great for batch variation);
  • 🔒 lock any slider and it is never touched by any randomize (manual or each-run).
• Best-effort auto-fill of min/max (and labels) from metadata. Slider LoRAs rarely expose their usable range as structured data — it's usually buried in the CivitAI description, e.g. "Strength: Safe zone (-3 - +2.5) … Higher is thinner." The node reads LM's stored description and parses the range + direction. Always editable via the per-row ⚙ config dialog; silently falls back to defaults when nothing is found.
• Outputs a standard LORA_STACK (+ aggregated trigger_words) that plugs straight into LM's Lora Loader (LoraManager).

Install

Clone into your ComfyUI/custom_nodes/ directory (next to ComfyUI-Lora-Manager):

cd ComfyUI/custom_nodes
git clone https://github.com/EnragedAntelope/ComfyUI-LoraSlider-LM

Restart ComfyUI. The node appears under the Lora Slider category as LoRA Slider (LoraManager). ComfyUI-Lora-Manager must be installed and running for the picker / pool import / metadata auto-fill features (they call LM's HTTP routes); the node still works for manual sliders without them.

Typical wiring

Lora Pool (LoraManager) ──POOL_CONFIG──▶ LoRA Slider ──LORA_STACK──▶ Lora Loader (LoraManager) ──▶ KSampler
                                              └────────▶ trigger_words (STRING)

How it stays decoupled from LoRA Manager

This package imports no LM Python modules and patches nothing. All integration is through LM's public HTTP API and shared ComfyUI types:

Need	LM route / mechanism
Picker search (by name or folder path)	GET /api/lm/loras/relative-paths
Expand a Lora Pool folder/tag selection	POST /api/lm/loras/cycler-list
Resolve a LoRA's file path	GET /api/lm/loras/list
Description for min/max parsing	GET /api/lm/loras/model-description
Apply the result to MODEL/CLIP	output LORA_STACK → LM's Lora Loader

The browser widget fetches metadata and serializes everything it needs into the node's saved value, so execution requires no network and no LM imports.

Development

# Python (node + metadata parser)
python -m pytest

# JS (strength-parser mirror)
node --test tests/strength_parser.test.mjs

nodes/metadata_parser.py and web/strength_parser.js implement the same heuristics — keep them in sync.
