StyleRef nodes for ComfyUI

Define a creative style once on StyleRef — colors, lighting, mood, composition, guardrails — then load it as a node and reuse it across FLUX, SDXL, SD1.5, and natural-language targets.

The style is compiled server-side for whichever model you point it at, so the same style produces prompt text phrased appropriately for each one.

No account needed to load and apply public gallery styles. An account adds your own private styles. Nothing in this plugin spends credits.

Install

ComfyUI Manager (recommended) — search for StyleRef and click Install.

Manually:

cd ComfyUI/custom_nodes
git clone https://github.com/StyleRef/styleref-comfyui

Restart ComfyUI. No dependencies to install — the pack uses only the Python standard library. Look for [StyleRef] v0.1.0 — 5 nodes registered in the server console at startup.

60-second quickstart

1. Add StyleRef Load and paste a slug from the gallery into style_ref (try sbdlwwly-66ae1a89efdc, the Renaissance Mythic Classicism style) — or click Search styles… to pick one.
2. Add StyleRef Apply, connect style, type a subject, pick your target.
3. Wire positive / negative into your CLIP Text Encode nodes.

Or drag workflows/01-quickstart.json onto the canvas.

Nodes

Node	Sign-in	What it does
StyleRef Load	No	Fetch a style by share slug or share URL — and, signed in, your own private styles by id or /styles/{id} URL. Includes gallery search with a picker dialog and a ↻ Refresh button.
StyleRef Apply	No	Compose a subject with a style into positive / negative prompts for a chosen target, with a prompt preview in the node body.
StyleRef Facets	No	Every schema section as its own output — exactly the style board's section list, plus the six custom style items.
StyleRef Reference Images	No	The style's inspiration images as an IMAGE batch — for IPAdapter and reference conditioning.
StyleRef Login	—	Status line + Sign in / Sign out buttons. Needed only to load your own private styles.

Targets

ai_tools, style_md, flux, midjourney, diffusion, json — exactly the web app's copy-box format list. For the sampler in your graph use flux (FLUX models) or diffusion (SDXL, SD1.5, DALL·E-class); the other four are for copying the output out of ComfyUI, and the node warns if one feeds a CLIP encoder.

Making your own styles

Extraction (turning an image into a style) happens on styleref.io — upload an image there, refine the result, and it lands in your library. Load it here by its share slug or id (sign in with the Login node first).

Workflow templates

File	Sign-in	Story
01-quickstart.json	No	Load → Apply → generate
02-consistency-grid.json	No	One style, three subjects, side by side
03-your-own-style.json	Yes	Extract on the web, load your own style here
04-facets.json	No	Every section of the style as its own output, next to a normal render

A parallel set wired for Z-Image Turbo (an S3-DiT model — UNET + Qwen text encoder + VAE, compiled from the diffusion target) lives in workflows/z-image/: the same quickstart, consistency, your-own-style and facets stories, plus a reference-images demo. The three model files download on first run.

Z-Image takes no negative prompt. It runs without classifier-free guidance, so the Z-Image templates carry no negative encoder — the sampler's negative input gets a zeroed conditioning, as in a FLUX graph. StyleRef still compiles the negative and previews it on the canvas; fold anything you need from it into subject on Apply as a positive phrase. Raising CFG does not bring it back.

Signing in

Add the StyleRef Login node and click Sign in (browser) — no queueing needed. Your browser opens, you approve, and the node's status flips to signed in. The token is stored at ~/.config/styleref/credentials.json with 0600 permissions. The styleref CLI shares this login.

(No frontend at all? npx styleref login signs in the same credentials file, and queueing the Login node reports the current status.)

Running ComfyUI on a remote or headless machine

Browser sign-in cannot work on a rented GPU box, RunPod, or any headless server: there is no browser to open, and localhost is the wrong machine. Use a token instead:

1. Copy a token from your account page.
2. Where ComfyUI runs, set STYLEREF_TOKEN=<token>
3. Restart ComfyUI.

STYLEREF_TOKEN always takes precedence over stored credentials. The Login node detects the headless case and prints these instructions rather than hanging.

Credits

Nothing in this plugin spends credits. Loading, searching, and applying styles is free and unlimited within the public rate limit. Extraction — the one paid action — happens on styleref.io, where you can preview and refine the result before it costs anything beyond the extraction itself. See plans and limits.

Configuration

Variable	Purpose
STYLEREF_TOKEN	Bearer token; overrides stored credentials. The headless path.
STYLEREF_API	API base URL. Defaults to https://styleref.io/api/v1.
STYLEREF_FORCE_BROWSER_LOGIN	1 forces browser login, 0 forces the token path.

Development

pip install pytest ruff pillow numpy   # pillow/numpy are test-only deps
pytest tests/ -q
ruff check .
python scripts/build_workflows.py   # regenerate workflow templates

The workflow templates are generated — edit scripts/build_workflows.py, not the JSON.

The nodes are a thin client over StyleRef's public REST API v1 (OpenAPI). All prompt compilation happens server-side — this pack never writes style prose itself, so improvements to StyleRef's compiler reach you without a plugin update.
