+# ComfyUI HTTPS Bridge
+
+A ComfyUI custom node that automatically starts a local HTTPS proxy server, enabling web applications deployed on public HTTPS pages to securely connect to your local ComfyUI instance.
+
+## The Problem
+
+Modern browsers block connections from HTTPS pages to HTTP endpoints (mixed content policy). This means if you use a ComfyUI web UI hosted on `https://yourapp.com`, it cannot directly connect to your local `ws://localhost:8188`.
+
+## The Solution
+
+This node starts a local HTTPS proxy on port 9999 that sits between the browser and ComfyUI:
+
+```
+Browser (HTTPS page)
+    ↓  wss://localhost:9999  (trusted self-signed cert)
+ComfyUI HTTPS Bridge  ← this node
+    ↓  ws://localhost:8188   (local, no restrictions)
+ComfyUI
+```
+
+## Features
+
+- **Zero configuration** — starts automatically when ComfyUI loads
+- **No external tools required** — generates self-signed certificates using Python's `cryptography` library
+- **Auto-detects ComfyUI address** — reads `--listen` and `--port` startup arguments automatically
+- **Smart IP detection** — when ComfyUI uses `--listen 0.0.0.0`, resolves to the actual local network IP
+- **Full proxy support** — handles HTTP requests, WebSocket connections, and image streaming
+
+## Installation
+
+### Via ComfyUI Manager
+Search for `ComfyUI-HTTPS-Bridge` and install.
+
+### Manual
+```bash
+cd ComfyUI/custom_nodes
+git clone https://github.com/caissonfiv/comfyui-https-bridge.git
+```
+
+Then install dependencies:
+```bash
+pip install -r custom_nodes/comfyui-https-bridge/requirements.txt
+```
+
+Restart ComfyUI. The bridge starts automatically in the background.
+
+## First-Time Browser Setup (Once Only)
+
+Because the certificate is self-signed, your browser needs a one-time authorization:
+
+1. Open **https://localhost:9999** in your browser
+2. Click **Advanced** → **Proceed to localhost**
+3. You'll see a blank page — that means it's working
+
+After this, the browser remembers the exception permanently.
+
+## Usage
+
+In your ComfyUI web app's connection settings, enter:
+```
+https://localhost:9999
+```
+
+You should see "ComfyUI Connected" in the app.
+
+## Configuration
+
+All settings are optional via environment variables:
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `COMFY_BRIDGE_PORT` | `9999` | HTTPS bridge port |
+| `COMFY_HOST` | auto-detected | Override ComfyUI host |
+| `COMFY_PORT` | auto-detected | Override ComfyUI port |
+
+**Address detection priority:**
+1. Environment variables `COMFY_HOST` / `COMFY_PORT` (highest)
+2. ComfyUI startup args `--listen` / `--port` (auto-read)
+3. Default `127.0.0.1:8188`
+
+**Example — custom port:**
+```bash
+COMFY_BRIDGE_PORT=9998 python main.py
+```
+
+**Example — remote ComfyUI:**
+```bash
+COMFY_HOST=192.168.1.50 COMFY_PORT=8188 python main.py
+```
+
+## Requirements
+
+- Python 3.8+
+- `cryptography` — for self-signed certificate generation
+- `aiohttp` — for the HTTPS proxy server (already included in ComfyUI)
