What is it?

Key features

• 01Phone-optimized React interface that auto-generates forms from each workflow.
• 02Requests Colab GPUs only when a generation starts and releases them after saving output.
• 03Caches ComfyUI environments and model weights in Google Drive.
• 04Background job queue with a watchdog that cleans up timed-out runs.
• 05Ships with four built-in workflows for image and video generation.
• 06Docker Compose deployment with API, worker and watchdog containers.

Use cases

• Generating images from a phone without managing ComfyUI node graphs by hand.
• Running image-to-video jobs on a rented Colab GPU while keeping the web app on a small VPS.
• Keeping large model downloads cached in Drive so repeated runs skip reinstallation.
• Running a private, single-user AI creation station rather than a multi-tenant service.

Quick start

1. 1

   Generate your private .env configuration file

   uv run python scripts/init_env.py --site-url https://你的域名
2. 2

Things to know

• !Licensed under AGPL-3.0, so modified versions offered over a network must also be published as source.
• !Real Google Colab GPU use is disabled by default and needs your own Google OAuth setup, budget limits and workflow review.
• !Designed for personal self-hosted use only, with no multi-tenant isolation.
• !Built-in real workflows stay as drafts until you verify them, and the README says the offline acceptance CI has not run on GitHub Actions yet.
