chamdev-nodes

Custom ComfyUI node pack by chamdev.

Nodes

Champdev Save Image

Save-image output node compatible with ComfyUI's standard image flow, with extra controls for temporary output and filename handling.

Inputs:

• images (IMAGE)
• filename_prefix (STRING)
• save_to_comfy_temp_dir (BOOLEAN): saves to ComfyUI temp directory instead of output directory.
• overwrite_existing (BOOLEAN): when fixed filename mode is on, overwrite existing file instead of auto-increment fallback.
• fixed_filename_no_increment (BOOLEAN): save using a fixed filename (no default counter suffix).
• auto_delete_after_seconds (INT): delete saved file after N seconds (0 disables).

Champdev Save video

Save-video output node that follows core Save Video behavior (takes a VIDEO input and saves via Comfy's video pipeline), with extra file-handling options.

Inputs:

• video (VIDEO)
• filename_prefix (STRING)
• format (auto + core-supported containers)
• codec (auto + core-supported codecs)
• save_to_comfy_temp_dir (BOOLEAN)
• overwrite_existing (BOOLEAN)
• fixed_filename_no_increment (BOOLEAN)
• auto_delete_after_seconds (INT)

Champdev File Manager

A utility node (ChampdevFM) that embeds a file manager in its body. Browse any folder on the machine running ComfyUI, preview images, play video/audio, and manage files.

Widgets:

• start_path (STRING): folder the manager opens at (defaults to the output directory).
• show_hidden (BOOLEAN): show dotfiles.

Features: editable path bar (Enter to jump anywhere), up/refresh, filter, sortable columns, multi-select, a resizable side preview that shows the original image (click it for full screen), full-screen preview for images/video/audio with ←/→ to step through them, and these operations — upload (button or drag-and-drop), download, rename, move, copy, new folder, delete (with confirmation), and properties.

Keyboard: with the list focused, ↑/↓ move the selection (the preview updates) and Enter opens full screen; Esc closes it. Large folders load lazily — rows and their thumbnails are fetched ~20 at a time as you scroll, and the list scrolls inside the node.

⚠️ Security: this node can read, rename, move, and delete files anywhere the ComfyUI server process can access. It is meant for local, single-user use only. Do not enable it on a ComfyUI instance exposed to a network (--listen, reverse proxy, or shared host): anyone who can reach the UI could delete or exfiltrate arbitrary files. Use at your own risk.

Champdev Terminal

A utility node (ChampdevTerminal) that embeds a full interactive terminal in its body, backed by a real pseudo-terminal on the machine running ComfyUI. Supports interactive programs (vim, top), ANSI colors, and resizing.

Widgets:

• shell (STRING): shell to launch (default empty = auto-detect — $SHELL or /bin/bash//bin/sh on macOS/Linux; on Windows, PowerShell (pwsh.exe, then the built-in powershell.exe), falling back to cmd.exe).
• start_dir (STRING): working directory the shell starts in (defaults to the output directory).

The shell session is fresh per connection: it starts when the terminal connects and is killed when you close/reload (the ⟳ Restart button starts a new shell). macOS/Linux use the Python standard library (no extra dependency); Windows requires the pywinpty package (see Installation — installed from requirements.txt).

⚠️ Security: this node opens a fully interactive shell on the machine running ComfyUI — arbitrary command execution by design. It is for local, single-user use only. Do not enable it on a network-exposed ComfyUI (--listen, reverse proxy, or shared host): anyone who can reach the UI gets a shell on your machine. Use at your own risk.

Installation

Easiest: install via ComfyUI-Manager, which installs dependencies for you.

To install manually, clone into your ComfyUI custom nodes directory and install the dependencies with the same Python that runs ComfyUI:

cd /path/to/ComfyUI/custom_nodes
git clone https://github.com/rohit267/chamdev-comfyui-nodes.git
cd chamdev-comfyui-nodes
# ComfyUI portable: use python_embeded\python.exe instead of `python`
python -m pip install -r requirements.txt

Restart ComfyUI.

macOS/Linux have no dependencies (the terminal uses the Python standard library). On Windows the terminal needs pywinpty; the command above (and ComfyUI-Manager) installs it. If it's missing, the terminal shows the exact pip install command to run.

Compatibility

• Python 3.10+
• ComfyUI (recent versions)
