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, full-screen preview for images/video/audio, side properties pane, and these operations — upload (button or drag-and-drop), download, rename, move, copy, new folder, delete (with confirmation), and properties.

⚠️ 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, cmd.exe on Windows).
• 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 (installed automatically on Windows).

⚠️ 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.
