# ComfyUI Bridge
Generate images, faceswap, animate expressions, and do style transfer via a self-hosted [ComfyUI](https://github.com/comfyanonymous/ComfyUI) instance running on your LAN. No cloud API — your GPU, your models.
## Requirements
- ComfyUI Desktop (or server) running somewhere on your LAN
- [ComfyUI Bridge server](https://github.com/Bortlesboat/comfyui-bridge) running on the same machine as ComfyUI (see Setup)
- `uv` installed on the machine running OpenClaw
## Setup
### 1. Install the bridge server (on your ComfyUI machine)
The bridge is a lightweight FastAPI server that wraps ComfyUI's API:
```bash
git clone https://github.com/Bortlesboat/comfyui-bridge
cd comfyui-bridge
pip install -r requirements.txt
python bridge_server.py
# Listening on http://0.0.0.0:8100
```
### 2. Configure the skill
Set the bridge URL as an environment variable on your OpenClaw machine:
```bash
export COMFYUI_BRIDGE_URL=http://YOUR_COMFYUI_MACHINE_IP:8100
```
Or add it to your LaunchAgent/systemd service environment.
### 3. Required ComfyUI custom nodes (for all features)
Install via ComfyUI Manager:
- **ReActor** — faceswap
- **ComfyUI-LivePortrait** — expression animation
- **ComfyUI_IPAdapter_plus** — style transfer
- **WAS Node Suite** — utilities
- **ComfyUI-GGUF** — GGUF model support (optional, for FLUX)
- **rgthree-comfy** — workflow utilities
### 4. Recommended models
| Model | Use |
|---|---|
| Juggernaut XL Ragnarok | Architecture, objects, general |
| RealVisXL V5.0 Lightning | People, portraits, fast |
| FLUX.1 Dev Q5 GGUF | Maximum photorealism (slow, VRAM-heavy) |

## Usage
All commands use the `comfyui_generate.py` script via `uv run`. Replace `SKILL_SCRIPTS` with the path to this skill's `scripts/` directory.
**Always use `--no-media`** — include one `MEDIA: /full/path/to/output.png` in your text response instead.
### 1. Text to Image
```bash
uv run $SKILL_SCRIPTS/comfyui_generate.py \
--prompt "your description" \
--filename ~/.openclaw/media/outbound/output.png \
--no-media
```
### 2. Image to Image
```bash
uv run $SKILL_SCRIPTS/comfyui_generate.py \
--prompt "make it sunset" \
-i /path/to/input.png \
--strength 0.5 \
--filename ~/.openclaw/media/outbound/output.png \
--no-media
```
### 3. Faceswap (pipeline — best quality)
Swaps a face then runs img2img cleanup for natural blending. ~30 seconds total.
```bash
uv run $SKILL_SCRIPTS/comfyui_generate.py \
--faceswap-pipeline \
--source-face /path/to/source_face.png \
-i /path/to/target.png \
--cleanup-strength 0.40 \
--filename ~/.openclaw/media/outbound/output.png \
--no-media
```
### 4. Faceswap (basic)
```bash
uv run $SKILL_SCRIPTS/comfyui_generate.py \
--faceswap \
--source-face /path/to/source_face.png \
-i /path/to/target.png \
--filename ~/.openclaw/media/outbound/output.png \
--no-media
```
### 5. Targeted Faceswap (specific face in group photo)
```bash
uv run $SKILL_SCRIPTS/comfyui_generate.py \
--targeted-faceswap \
--source-face /path/to/source_face.png \
-i /path/to/group_photo.png \
--target-face-index "1" \
--filename ~/.openclaw/media/outbound/output.png \
--no-media
```
Face indices: `0` = leftmost, `1` = second from left, `"0,2"` = first and third.
### 6. LivePortrait (expression animation)
```bash
uv run $SKILL_SCRIPTS/comfyui_generate.py \
--liveportrait \
-i /path/to/portrait.png \
--expression-preset smile \
--filename ~/.openclaw/media/outbound/output.png \
--no-media
```
Presets: `smile`, `surprised`, `wink`, `suspicious`, `derp`, `angry`, `sleepy`
Fine-grained control: `--smile` (-0.3 to 1.3), `--blink-val` (-20 to 5), `--eyebrow-val` (-10 to 15), `--aaa` (-30 to 120, mouth open), `--pitch`/`--yaw`/`--roll` (-20 to 20, head rotation).
### 7. Style Transfer
Generate a new image in the style of a reference:
```bash
uv run $SKILL_SCRIPTS/comfyui_generate.py \
--style-transfer \
--style-ref /path/to/reference.png \
--prompt "a portrait of a man" \
--style-weight 0.85 \
--filename ~/.openclaw/media/outbound/output.png \
--no-media
```
### 8. Restyle
Apply a reference image's style to an existing photo:
```bash
uv run $SKILL_SCRIPTS/comfyui_generate.py \
--restyle \
--style-ref /path/to/reference.png \
-i /path/to/photo.png \
--style-weight 0.85 \
--strength 0.65 \
--filename ~/.openclaw/media/outbound/output.png \
--no-media
```
### 9. Enhanced mode
Add `--enhanced` to any command for FaceDetailer + 4x-UltraSharp upscale (net ~2x resolution). Works with txt2img and faceswap.
---
## Quality Gates (built-in)
The script includes two automatic quality checks on faceswap outputs:
**Gate 1 — Size check:** ReActor blank outputs when no face is detected (~2KB). Any faceswap output under 10KB automatically retries once. If still blank, exits with `FACESWAP_BLANK:` error — no garbage delivered.
**Gate 2 — Vision QA:** If you have [Ollama](https://ollama.ai) running locally with `gemma3:12b`, faceswap outputs are checked with vision QA before delivery. PASS → deliver normally. FAIL → file renamed `_qa_flagged` and still delivered. Add ~10-20s but catches glitchy outputs. Disable by not having Ollama/gemma3 installed (fails open).
---
## Offline Queue
When the bridge is unreachable, requests are automatically queued to `~/.openclaw/faceswap-queue/`. A companion daemon (`queue_processor.py`) polls every 5 minutes and delivers via iMessage when the bridge comes back online.
Tell users: "Got it — the system is offline right now but your request is queued and will be sent automatically when it comes back."

| "make him smile / look surprised" | --liveportrait --expression-preset |
| "generate something that looks like this painting" | --style-transfer |
| "make this photo look like a painting" | --restyle |
