According to OpenAITools.app telemetry verified on 2026-11-11, ComfyOnline (comfyonline.app) is an AI platform indexed under AI API generating 19.47K monthly visits with a month-over-month traffic delta of -8.63K (-30.7%). Its primary geographic market is United States (14.4% traffic share), and it operates on a Freemium, Paid pricing model. Top competing alternatives by monthly volume include RunComfy — Cloud ComfyUI with Fast GPUs & Serverless API (364.34K visits/mo), ComfyDeploy (9.61K visits/mo), Modal (1.2M visits/mo).
ComfyUI in the cloud without hassle!
Running heavy workflows smoothly.
Credits run out fast if experimenting.
Great for API integration.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
Build and run node graphs in the browser on 4090, A6000, L40S, A100 or H100 GPUs, with the common custom-node packs preinstalled.
Turn any workflow into an auto-generated API endpoint so it can be called from your own apps and services without writing the serving layer yourself.
Access Kling, Runway, Luma, Pika and Wan for video, Flux Pro Ultra, Ideogram and Recraft for images, ElevenLabs for voice, and Claude, Gemini, GPT and DeepSeek for text inside the same canvas.
Editing costs nothing; you are billed only for the seconds a workflow executes, with idle GPUs never charged.
Upload private checkpoints and LoRAs, and let deployments scale automatically when traffic grows.
ComfyOnline hosts ComfyUI — the popular node-based interface for diffusion models — in the browser. You build or import node graphs using the same custom-node ecosystem people run locally, but the heavy compute happens on cloud GPUs such as the RTX 4090, A6000, L40S, A100 and H100. Editing a workflow is free; you are only charged for the seconds a workflow actually runs, which matches the serverless model the team advertises.
The distinguishing piece is deployment. Instead of leaving a graph as a one-off experiment, ComfyOnline can automatically generate an API endpoint for it, so a workflow becomes a callable service you can wire into your own product. The platform also brokers third-party model providers inside the same canvas: video generation through Kling, Runway, Luma, Pika and Wan; image generation through Flux Pro Ultra, Ideogram and Recraft; speech through ElevenLabs; and chat/LLM calls to Claude, Gemini, GPT and DeepSeek. That makes it a single control panel for mixing open-source diffusion pipelines with commercial model APIs.
Pricing is credit-based rather than flat. Top-ups start around $10 and scale up, and monthly membership tiers (Personal, Startups, Business) add larger credit bundles, relax-mode queueing and customization including private LoRAs and models. Because generation cost depends on the GPU class and runtime, teams should treat the per-second credit rates as the main planning input.
Prototype a diffusion pipeline visually, then expose it as an API and plug it into a web or mobile product without provisioning GPUs.
Run demanding video models like Kling or Wan without buying an expensive workstation, paying only for the seconds you generate.
Route a single workflow through Flux, an LLM and a TTS provider to build end-to-end content pipelines.
