RunComfy

RunComfy is a web platform with an API that lets artists and hobbyists run ComfyUI workflows in the cloud without local installation, using on-demand GPU machines.

Key capabilities include:

• Browser-based ComfyUI sessions with a pre-configured environment, plus 200+ ready-to-run templates for common image and video workflows.
• Workflow management and reproducible environments, where a saved workflow captures the workflow JSON plus the underlying OS/Python setup, nodes, and models.
• Model and node support, including downloading models from sources like Civitai and Hugging Face, persisting models across sessions, and installing nodes via ComfyUI-Manager.
• Production deployment options, including deploying a saved workflow as a serverless ComfyUI API endpoint that can autoscale with demand (a basic API option may not autoscale and can have longer cold starts).

Pricing: Pay as You Go GPU billing based on instance uptime (per-second), with tiered hourly rates (for example, Medium $0.99/hour and 3X-Large $8.75/hour). A Pro subscription offers 20% to 30% discounts on Pay as You Go rates.

Notable for combining an unmodified ComfyUI experience with cloud-saved, shareable workflow environments, so users can move between local and cloud setups while keeping nodes, models, and runs consistent.
