ComfyUI vs Leonardo AI: pricing
Every tier both tools publish, as we last checked them — not just the entry price.
ComfyUI
- Desktop (self-hosted)Free, open-source local app; requires the user's own GPU and models.Free
- Cloud Free5 free runs on real GPUs, no credit card required.Free
- Cloud Standard$192/year billed annually; 4,200 monthly credits (~380 five-second videos); 30-minute max workflow runtime; no custom model importing.$16/mo
- Cloud Creator$336/year billed annually; 7,400 monthly credits (~670 five-second videos); adds custom model importing from CivitAI or Hugging Face.$28/mo
- Cloud Pro$960/year billed annually; 21,100 monthly credits; extended runtime up to 1 hour; custom model importing included.$80/mo
- Cloud TeamStarts at $630/month up to $2,500/month depending on seats, shared credit pool of 147,700 monthly credits, up to 20% off on annual billing.$630/mo

Leonardo AI
- FreeLimited daily generation tokens for trying the platform's models and canvas tools; exact current daily allowance not verified on-site.Free
- Paid subscription tiersMultiple paid tiers (historically named Apprentice, Artisan, and Maestro) scale by monthly token allowance and unlock features like private generations and priority queue; leonardo.ai blocked automated fetches (403/429 responses) on every attempt, so current tier names and dollar prices could not be confirmed and are not reported to avoid publishing stale numbers.Custom
Which is easier to use, ComfyUI or Leonardo AI?
Leonardo AI is easier to use, with a moderate learning curve and a browser-based prompt-and-canvas workflow, while ComfyUI's node-based interface carries a steep learning curve.
ComfyUI replaces the prompt box with a canvas of connected nodes for checkpoints, sampling, conditioning, and output, so users must understand how a generation pipeline fits together before getting good results. Leonardo AI keeps generation in a web app and lets users fix an image afterward with inpainting, outpainting, and upscaling instead of rebuilding the pipeline. The trade-off is that Leonardo AI's many checkpoints behave differently, so users still experiment to find a reliable model.
ComfyUI vs Leonardo AI pricing: which costs less?
ComfyUI costs less for anyone with a capable GPU, because the open-source ComfyUI desktop app is free with no usage caps, while Leonardo AI meters generations with tokens and its current paid prices could not be verified.
Without local hardware, Comfy Cloud gives 5 free runs, then charges $16/month billed annually for 4,200 credits on Standard, $28/month for 7,400 credits and custom model importing on Creator, and $80/month for 21,100 credits on Pro. Comfy Cloud Team starts at $630/month. Leonardo AI has a free tier with a limited daily token allowance and paid tiers that scale by monthly tokens and unlock private generations and a priority queue. Both credit systems drain faster on longer or higher-resolution work.
Does ComfyUI or Leonardo AI need a powerful GPU?
ComfyUI needs a capable local GPU to run for free, while Leonardo AI runs entirely in the browser on hosted hardware.
The ComfyUI desktop app installs on Windows, macOS, and Linux and runs against the user's own GPU and models. Users without one can move to Comfy Cloud, but credits are consumed quickly by longer video workflows, and Cloud Standard caps a workflow at 30 minutes of runtime, while Cloud Pro extends that to 1 hour. Leonardo AI has no desktop or mobile app, so any device with a browser works.
Can Leonardo AI replace ComfyUI?
Leonardo AI can replace ComfyUI for creators who want quick image and short video generation with in-app editing, but not for professionals who need node-level control, custom pipelines, or local generation.
Leonardo AI covers the common path: pick a fine-tuned model, prompt, then fix the result on the canvas. ComfyUI users who depend on shareable workflow files, 60,000+ community nodes, importing their own models from CivitAI or Hugging Face, 3D or audio pipelines, or the Comfy API for production systems would not find those in the Leonardo AI listing data.
Strengths and weaknesses
ComfyUI
Pros
- Free, open-source desktop app with no usage caps when run on local hardware.
- Node-based workflow editor exposes every parameter instead of hiding pipeline steps behind a single prompt box.
- 60,000+ community nodes and shareable workflow files for reproducing complex pipelines.
- Supports custom model importing from CivitAI and Hugging Face on paid Cloud tiers.
Cons
- Steep learning curve for users coming from single-prompt tools like Midjourney or DALL-E.
- Local use requires a capable GPU; without one, users must pay for Comfy Cloud credits.
- Cloud Standard tier blocks custom model importing, forcing an upgrade to Creator for that workflow.
- Credit-based Cloud pricing is harder to predict than a flat monthly fee, especially for longer video generations.
Leonardo AI
Pros
- Wide selection of fine-tuned and community models instead of being locked to one house style.
- Built-in canvas editor supports inpainting, outpainting, and upscaling without leaving the app.
- Free tier lets new users test multiple models before committing to a paid plan.
- Backed by Canva's resources following the 2024 acquisition, which has expanded its creative-suite integrations.
Cons
- Token-based credit system means heavy generation and editing use can exhaust a monthly plan quickly.
- Model quality and prompt behavior vary across the many available checkpoints, requiring experimentation to find a reliable one.
- No native desktop or mobile app; browser-only workflow.
- Current pricing was not independently verifiable because leonardo.ai blocked automated page fetches.
Which fits your use case?
| Use case | Pick | Why |
|---|---|---|
| VFX or animation studio standardizing one generation pipeline across artists | ComfyUI | ComfyUI's node graph exposes every step, and its shareable workflow files and 60,000+ community nodes let a team reproduce the same pipeline. |
| Marketer with no GPU who needs campaign visuals quickly | Leonardo AI | Leonardo AI runs in the browser with a free tier and a moderate learning curve, and its canvas handles inpainting and upscaling without extra tools. |
| Hobbyist with a gaming GPU who wants unlimited free generation | ComfyUI | The ComfyUI desktop app is free and open source with no usage caps on local hardware, while Leonardo AI's free tier limits daily tokens. |
| Game artist who needs consistent-style assets with quick touch-ups | Leonardo AI | Leonardo AI offers fine-tuned and community checkpoints for game assets and character art, plus inpainting and upscaling in the same workspace. |
| Developer embedding image or video generation in a product | ComfyUI | Comfy offers an API for embedding ComfyUI workflows into production systems; the Leonardo AI listing data does not describe an API. |
Neither a match?
Both lists carry verified pricing and honest weaknesses for every option.

ComfyUI vs Leonardo AI: migration FAQ
Should I use ComfyUI or Leonardo AI?
- Use ComfyUI if you have a capable GPU and want free, open-source, node-level control over generation pipelines; use Leonardo AI if you want browser-based image and video generation with fine-tuned models and canvas editing and no hardware to manage.
Is ComfyUI cheaper than Leonardo AI?
- Yes if you run ComfyUI locally, since the ComfyUI desktop app is free and uncapped on your own GPU. Both have free tiers, Comfy Cloud starts at $16/month billed annually, and Leonardo AI's current paid prices could not be verified.
Can Leonardo AI replace ComfyUI?
- Partly: Leonardo AI covers prompt-based image and short video generation with inpainting and upscaling. The Leonardo AI listing data shows no equivalent to ComfyUI's node graph, local desktop app, or 3D and audio pipelines.
Is ComfyUI free?
- Yes, the ComfyUI desktop app is free and open source under GPL-3.0, with no usage caps on your own hardware. Comfy Cloud adds 5 free GPU runs, then paid plans from $16/month billed annually.
