## ComfyOnline

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.

**Pricing & Plans:** Freemium-style: editing workflows is free and you pay only for runtime. Pay-as-you-go credit packs start around $10 (with bonus credits), and monthly membership tiers such as Personal, Startups and Business unlock larger credit bundles, unlimited relax-mode queues and custom deployment options.

- **Cloud ComfyUI workspace:** Build and run node graphs in the browser on 4090, A6000, L40S, A100 or H100 GPUs, with the common custom-node packs preinstalled.
- **One-click API deployment:** 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.
- **Built-in model brokers:** 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.
- **Pay-per-second billing:** Editing costs nothing; you are billed only for the seconds a workflow executes, with idle GPUs never charged.
- **Private models and scaling:** Upload private checkpoints and LoRAs, and let deployments scale automatically when traffic grows.

**Strengths:** No local GPU needed; runs on high-end cloud cards; Workflow-to-API generation removes a big chunk of backend work; Wide list of third-party video, image, audio and LLM integrations; Transparent per-second credit pricing with no idle charges

**Limitations:** Credit-per-second math takes some effort to forecast real spend; Some advanced GPU tiers require specific plan upgrades; Documentation and enterprise terms are thinner than larger cloud vendors

## ThinkDiffusion

Running open-source image and video generation locally is powerful but painful: driver conflicts, Python environments, VRAM limits, and the constant hunt for a capable GPU. ThinkDiffusion removes that friction by putting a dedicated, private machine in the cloud behind a browser tab. You sign up, launch a machine in about 90 seconds, and immediately have the same interfaces the open-source community uses — Automatic1111, ComfyUI, Fooocus, Forge and Kohya — running with full access, without managing any of the installation yourself.

The workspace model is what sets it apart from a simple image generator. Because each machine is dedicated to one user and backed by persistent storage of up to 200 GB, your files, models, extensions and settings stay exactly where you left them. You can run several machines simultaneously for parallel experiments, upload checkpoints and LoRAs in one click from Civitai, Hugging Face or your own computer, and install any community extension or ComfyUI custom node you like. An auto-stop timer prevents a forgotten session from quietly burning through your credits.

Pricing reflects that flexibility. The Hobby tier is pure pay-as-you-go with a free 15 minutes on sign-up and no subscription. TD-PRO adds a monthly balance credit, larger persistent storage and discounted machine rates, while TD-TEAMS provides shared workspaces for collaborators. For organisations, there are education programs, TD-Edge training and consultancy, and a studio service that delivers finished generative AI work for brands, agencies and universities.

**Pricing & Plans:** Free to start with 15 minutes of usage on sign-up. The Hobby tier is pay-as-you-go at standard hourly machine rates with no subscription. TD-PRO is about $29.99 per month month-to-month or $19.99 per month billed yearly, adding $10 in monthly credits, 200 GB storage and 20% discounted machine rates. TD-TEAMS is around $59.99 per month including two members and $20 in monthly credits, and custom quotes cover enterprise, education and studio services.

- **One-click cloud AI art lab:** Launch a private, dedicated GPU machine in roughly 90 seconds with no installs, drivers or local hardware required, and drive it from any device including a phone.
- **A1111, ComfyUI, Fooocus, Forge and Kohya:** Run industry-standard open-source interfaces side by side — Automatic1111, ComfyUI, Fooocus, Forge and Kohya — and launch multiple machines at once for parallel work.
- **Any model or extension, one click:** Pull models, checkpoints, LoRAs, embeddings and textual inversions from Civitai, Hugging Face or your own drive in one click, and add any extensions or custom nodes.
- **Private, persistent workspace:** Each machine is yours alone, with up to 200 GB of persistent private storage, an auto-stop timer, and file access without launching a machine.
- **Teams, education and studio services:** Beyond self-serve workspaces there are packages for teams, education programs for schools and students, and a studio offering full-service generative AI production.

**Strengths:** Private, dedicated GPU machines with no local installation or hardware to manage; Runs the full open-source toolset: Automatic1111, ComfyUI, Fooocus, Forge and Kohya; Generous persistent storage (up to 200 GB) that survives between sessions; One-click model uploads from Civitai or Hugging Face and free extension installation

**Limitations:** Pay-as-you-go machine hours can add up quickly for heavy users unless you use the auto-stop timer diligently; The breadth of open-source UIs (A1111, ComfyUI, Forge, Kohya) has a learning curve for newcomers; You need to bring or find your own models, LoRAs and workflows rather than relying on a curated gallery; Annual savings and credits apply mainly to the paid TD-PRO and TD-TEAMS tiers
