Official front-end implementation of ComfyUI.
The project follows a structured release process for each minor version, consisting of three distinct phases:
Code changes merged to the development branch
Feature Freeze - 2 weeks
Testing and stabilization of the codebase
Publication
Nightly releases are published daily at https://github.com/Comfy-Org/ComfyUI_frontend/releases.
To use the latest nightly release, add the following command line argument to your ComfyUI launch script:
--front-end-version Comfy-Org/ComfyUI_frontend@latest
The development of successive minor versions overlaps. For example, while version 1.1 is in feature freeze, development for version 1.2 begins simultaneously. Each feature has approximately 4 weeks from merge to ComfyUI stable release (2 weeks on main, 2 weeks frozen on RC).

v1.5: Native translation (i18n)
ComfyUI now includes built-in translation support, replacing the need for third-party translation extensions. Select your language
in Comfy > Locale > Language to translate the interface into English, Chinese (Simplified), Russian, Japanese, Korean, or Arabic. This native
implementation offers better performance, reliability, and maintainability compared to previous solutions.
