ComfyUI will replace legacy frontend effective from 15 August 2024

Starting August 15, 2024, ComfyUI will replace their legacy frontend with a new and improved version. The new frontend is available at ComfyUI Frontend.

Why a New Frontend?

The current ComfyUI frontend is built using vanilla JavaScript ESM modules without package management, leading to significant development challenges.

This approach has often required reinventing solutions for problems that already have established, efficient answers.

To address these issues, the new frontend leverages TypeScript, Vue, and Vite, providing a more robust and maintainable codebase.

A custom shim extension in the Vite build process ensures full compatibility with the existing frontend extension ecosystem. This new tech stack is expected to significantly accelerate the development of new frontend features.
