The registry's Updates section was empty for every version because the publish workflow never passed a changelog. comfy-cli reads COMFY_NODE_CHANGELOG, so the workflow now builds it from the version's CHANGELOG.md section. The registry shows it as one plain paragraph (no Markdown), so the script keeps the first column of each table row. Releases also date that CHANGELOG section and get an annotated vX.Y.Z tag; CLAUDE.md and /version-bump describe the steps.
ComfyUI-FLUX-BFL-API
Custom nodes for integrating Flux models with the BFL API.
Installation
Option 1: Install via Custom Nodes Manager
- Open the Custom Nodes Manager.
- Search for "ComfyUI-FLUX-BFL-API".
- Select the package and follow the installation instructions.
Option 2: Manual Installation
-
Clone the repository:
cd custom_nodes git clone https://github.com/gelasdev/ComfyUI-FLUX-BFL-API.git -
Install the required dependencies:
pip install -r requirements.txt -
Get your BFL API key from api.bfl.ai.
-
Add your API key to the
config.inifile:[API] X_KEY = YOUR_API_KEY BASE_URL = https://api.bfl.ai/v1/
Configuration
You can either use config.ini for a global API key, or connect a Flux Config (BFL) node directly to any generation node to override the key, base URL, and region per-node. If no config node is connected, config.ini is used automatically.
