Download the latest package from GitHub Releases.
Only x86_64 Linux packages are currently provided.
Download Arctic-ComfyUI-Helper.exe and run it directly. The current Windows release is a standalone executable and does not require an installer.
Optional terminal logging:
.\Arctic-ComfyUI-Helper.exe --nerdstatssudo apt install ./arctic-comfyui-helper_*_amd64.debInstall the RPM downloaded from GitHub Releases:
sudo dnf install ./arctic-comfyui-helper-*.x86_64.rpmAlternatively, install from the Arctic Helper COPR repository to receive updates through DNF:
sudo dnf copr enable burcebor/arctic-helper
sudo dnf install arctic-comfyui-helperDownload the native .pkg.tar.zst asset from the release and install it with:
sudo pacman -U ./arctic-comfyui-helper-*-x86_64.pkg.tar.zstAn AUR package is no longer published or maintained. Use the native Arch package attached to each GitHub release.
flatpak install --user ./arctic-comfyui-helper-*-x86_64.flatpak
flatpak run io.github.ArcticHelperRun without installing:
nix run 'tarball+https://github.com/ArcticLatent/Arctic-Helper/releases/latest/download/arctic-comfyui-helper-nix-x86_64.tar.gz'Install into your user profile:
nix profile add 'tarball+https://github.com/ArcticLatent/Arctic-Helper/releases/latest/download/arctic-comfyui-helper-nix-x86_64.tar.gz'Launch it with:
arctic-comfyui-helperUpdate the profile installation with:
nix profile upgrade --refresh arctic-comfyui-helperFor a declarative NixOS configuration, use the same tarball URL as a flake input and add inputs.arctic-helper.packages.${pkgs.system}.default to environment.systemPackages.
Nix installations check the signed release manifest and display the latest available version in the app. The How to Update action opens the latest release page and records Nix guidance in the application log. Installation remains delegated to Nix because applications cannot modify binaries in the immutable Nix store.
- Open the ComfyUI tab and choose Install New or Manage Existing.
- In Models or LoRAs, select your ComfyUI folder before downloading assets.
- Configure optional launch flags, add-ons, custom nodes, and your Civitai token as needed.
On supported installations, Arctic ComfyUI Helper checks the release manifests published in this repository.
- Windows uses
update.json. - Linux packages use
linux-release.jsonto select the matching Debian, Fedora, or Arch artifact. - Nix installations use the same signed Linux manifest to detect newer versions without downloading or installing them automatically.
- Release manifests are authenticated with Ed25519 signatures.
- Downloaded application files are verified against SHA-256 checksums before installation.
- Missing or invalid signatures and checksum mismatches are rejected.
- Nix profile installations are updated with
nix profile upgrade --refresh arctic-comfyui-helper; declarative installations are updated through their flake configuration and normal system rebuild.
- Windows 10/11 or a supported
x86_64Linux distribution - Current drivers for your NVIDIA, AMD, or Intel GPU setup
- An internet connection for the catalog, model downloads, and installer tasks
- Sufficient disk space for ComfyUI, Python environments, models, and LoRAs
- A Civitai API token for assets that require authentication
- If a LoRA reports an authorization error, add your Civitai token in the app and save it.
- If you use multiple ComfyUI installations, select the intended installation before downloading assets.
- Use the runtime console to inspect a ComfyUI process launched by Arctic Helper.
- Launch
arctic-comfyui-helper --nerdstatson Linux or use the Windows command above for advanced diagnostic output.
Open an issue and include:
- Operating system and version
- Package type:
.exe,.deb,.rpm,.pkg.tar.zst,.flatpak, or Nix - What you clicked
- What you expected
- What happened
- Relevant in-app log lines
- Exact terminal output from
--nerdstats, when possible
