ComfyUI CI container

Important

The ComfyUI CI container is now part of the ComfyUI_frontend monorepo. This repository is no longer maintained. See the CI container documentation for current usage, development, and publishing instructions. Report issues and submit pull requests in the monorepo. The instructions below describe the legacy standalone container.

This image runs ComfyUI frontend Playwright tests without installing the backend and browser dependencies in every CI shard.

Included software

• Chromium, Firefox, and WebKit from the pinned Playwright image
• Node.js 26 through fnm
• pnpm through Corepack
• zstd for GitHub Actions cache archives
• Python 3.12 and CPU-only PyTorch
• The pinned ComfyUI backend and its Python dependencies at /ComfyUI
• wait-for-it

Use the image

Replace <version> with a published container version. The container's Playwright version must match the caller's @playwright/test version.
