ComfyUI Desktop vs Portable (2026): Which Version to Install

For ComfyUI Desktop vs Portable, pick Desktop if you want a launcher that manages environments, updates, and multiple installations. Pick Portable if you want a Windows folder you launch and maintain yourself. Desktop can also launch an existing Portable installation. Desktop overview, Desktop repository.

What Desktop and Portable mean in 2026

The official app is called Comfy Desktop. It manages separate ComfyUI instances, each with its own environment. The archived Comfy-Org/desktop repository points to Comfy-Org/Comfy-Desktop. Desktop repository, archived repository.

Portable packages ComfyUI and an embedded Python environment for Windows. Extract the package that matches your GPU, then use its launcher. You interact with ComfyUI through a browser. Portable installation.

Both choices lead to ComfyUI workflows. Choose the installation around how you want to manage your working environment; choose models and workflows around the images you want to make.

ComfyUI Portable vs Desktop: comparison table

The Desktop column describes a newly created standalone instance. Adding an existing Portable folder as a tracked instance retains that folder's environment and manual maintenance requirements.

Table sources: Desktop requirements, Portable packages, instance controls, Manager installation, storage settings.

Which installation should you choose?

Choose Desktop for several managed setups. For example, keep one instance for your regular workflow and another for experiments. Desktop supports independent instances and snapshot management. Desktop usage guide.

Choose Portable for direct folder-based maintenance on Windows. Its launchers and update scripts make the entry points explicit. Keep the extracted package intact and use the instructions shipped with it. Portable guide.

Keep an existing working installation if it meets your needs. Try Desktop's tracking option before deciding to rebuild your environment. This is particularly useful when you already have custom nodes and carefully chosen dependencies.

A practical selection exercise: write down your required workflow, GPU, model locations, and essential nodes. Then decide whether you want those maintained through Desktop controls or through your Portable folder.

Compare the same workflow on your own hardware before making performance the deciding factor. Keep the model, resolution, and node choices consistent when evaluating whether a change helps your work.

Updates, Python, and ComfyUI-Manager

Desktop has two update layers. App updates maintain the launcher. Manage → Update controls the ComfyUI instance, with Stable as the default channel and Latest on GitHub for current master-branch commits. Update guide.

Portable's update directory contains these scripts:

• update_comfyui_stable.bat: move to the latest stable release.
• update_comfyui.bat: move to the development version.
• update_comfyui_and_python_dependencies.bat: update code and reinstall dependencies.

The official update guide warns that the dependency script can break custom nodes or overwrite package choices. Back up a working installation before using it to repair the environment. Portable update instructions.

Desktop includes Manager. For current Portable installations, the documented setup uses the bundled Python to install ComfyUI\manager_requirements.txt, then launches ComfyUI with --enable-manager. Manager setup.

Run these commands from the Portable package directory:

.\python_embeded\python.exe -m pip install -r ComfyUI\manager_requirements.txt
.\python_embeded\python.exe -s ComfyUI\main.py --windows-standalone-build --enable-manager

Use the installation's own Python for node dependencies. Pointing ComfyUI at a custom-node directory does not install that node's dependencies into another environment. Portable dependency guidance.

Migrating from Portable to Desktop

For a working Windows Portable setup, the documented route is tracking an existing installation. This adds it to Desktop without making a separate standalone environment. Tracking instructions.

1. Make a backup of your working Portable folder.
2. Install and open Comfy Desktop.
3. Select New Instance → Add Existing Instance.
4. Browse to the existing installation.
5. Check that the ComfyUI directory contains main.py, and that the Python environment points to the appropriate bundled folder, such as python_embeded.
6. Launch it and test a workflow you already use.

Tracking keeps the existing environment. The documentation distinguishes it from standalone instances: tracked installations need manual updates and do not support Desktop snapshots. Treat this as launcher integration, not an environment conversion.

If you want separate environments, create a new standalone instance instead. Rebuild its custom-node setup and test your workflows before relying on it for regular work. Share model files through storage paths to avoid a second model library.

Share one models folder with extra_model_paths.yaml

Choose a permanent model-library location. The example below assumes you create D:/AI/models with category subfolders. It is an illustrative configuration, based on ComfyUI's official configuration example.

In Portable, copy ComfyUI/extra_model_paths.yaml.example to ComfyUI/extra_model_paths.yaml. Add this mapping, replacing the base path with your actual folder:

shared_library:
  base_path: D:/AI/models
  checkpoints: checkpoints
  loras: loras
  vae: vae
  controlnet: controlnet
  text_encoders: text_encoders
  diffusion_models: diffusion_models
  upscale_models: upscale_models

These keys tell ComfyUI where to search for each model category. Restart after saving. The file belongs inside the Portable package's ComfyUI directory. Official YAML example.

In Desktop, open Desktop Settings → Storage → Add Shared Directory and select the same model root. In the instance's Manage → Storage panel, check Include Shared Directories. Storage settings.

Desktop's directory marked Primary receives new model downloads by default. Set that deliberately if you want future downloads in the shared library. Keep your configuration and model files backed up separately.

Moving back to Portable

For a tracked Portable installation, Untrack removes it from Desktop's list without deleting files. You can then use its original launcher. Avoid Uninstall / Delete when you intend to retain the installation. Instance actions.

For a Desktop standalone instance, build a fresh Portable setup and point its YAML configuration at your shared models. Install the nodes your workflows require into Portable's environment, then validate the workflows there.

Treat that second route as a manual move. Keep both setups until you have checked model selection, node availability, input files, and output locations. A successful launch alone is not a useful migration acceptance test.

Known limitations

Custom nodes can still conflict. Official troubleshooting identifies dependency mismatches and frontend-extension incompatibilities as failure causes. Disable custom nodes temporarily, then narrow down the offending package. Custom-node troubleshooting.

Manager can block an installation by policy. Desktop's Standard security level allows registered node packs and blocks unregistered sources. Check the policy before assuming a disabled install action means Manager is broken. Manager controls.

Documentation contains overlapping Desktop guidance. Some general pages still show legacy configuration-file locations. For the current app, use its dedicated Storage controls and platform-specific installation pages.

FAQ

Is ComfyUI Desktop faster than Portable?

Do not assume a speed advantage from the installation format. Choose by environment management and platform support, then measure your actual workflow.

Does ComfyUI Desktop support Linux?

Yes. Current Comfy Desktop documentation lists Linux packages in .deb and AppImage formats, alongside Windows and Apple Silicon macOS. Desktop overview.

Can Desktop and Portable share models?

Yes. Add the same model root to Desktop's shared storage and Portable's extra_model_paths.yaml. Keep custom-node dependencies within each installation's environment.

Do I need to install Python separately for Portable?

No. The official package includes embedded Python. Use that environment when installing its additional dependencies. Portable installation.
