Overview

RunComfy is a cloud platform for ComfyUI, the popular node-based interface for running open-source image and video generation models. It removes local setup so you can focus on creating rather than fixing errors, and it adds model APIs and training. RunComfy says it is trusted by more than one million creators and developers, offers over 200 templates, 99.9 percent uptime and 24/7 support.

ComfyUI in the browser

You can try ComfyUI in your browser without installation and start creating in seconds. The auto-setup agent is designed to save hours: drop a workflow.json file and RunComfy handles every dependency, custom node and model download, then gives you a link to open and run it. The site says the file is parsed locally. Full native ComfyUI is supported, so you can upload custom models and install any nodes. Dedicated private GPU machines range from 16 to 141 GB of VRAM, and any workflow can be turned into a serverless API with one click.

Models and training

The Models and API offering gives access to top open-source and commercial models with simple per-generation pricing. The Trainer runs long training jobs on 80 GB and 141 GB GPUs, releases GPUs automatically when training completes so there are no idle charges, and keeps persistent checkpoints so you can resume training.

Pricing

Pay as You Go requires no subscription and applies standard GPU rates, with 10 GB of storage and up to 10 saved workflow environments; inactive assets are removed after 90 days. Pro costs $19.99 a month billed yearly at $239.90, or $29.99 monthly. It adds a discount of 20 percent or more on GPU rates, 20 CPU hours a month for uploads and setup, a $10 monthly credit, unlimited saved environments, 200 GB of permanent storage and priority support.

Who it suits

RunComfy suits ComfyUI users without a powerful local GPU, developers deploying workflows as APIs and teams training custom models.

Things to consider

GPU time is billed while machines run, so shut down sessions when finished. Check licences for the models and custom nodes you use, especially for commercial work.
