ComfyUI is a graph-based interface for running diffusion models. Instead of a single prompt box, you wire together nodes (loaders, samplers, conditioning, upscalers and so on) into a workflow you can inspect, reuse and share. That transparency is the reason it became the go-to tool for people who want precise control over how an image or video is generated.
The current version is v0.27.0, released on June 30, 2026. It adds int8 quantized model support for Turing-generation GPUs and newer, with reworked LoRA and memory handling, plus new nodes including Seed, Advanced Krea 2 Model Merging, Bounding Box Canvas, ConditioningMultiply and an Ideogram JSON prompt node, and support for Google's Nano Banana 2 Lite. It builds on a busy 2026: a full Comfy Desktop overhaul in June brought multi-instance management, snapshots and shared model storage, and the project added Krea2 and LTX2 video models, official AMD ROCm support on Windows, and NVFP4 GPU performance upgrades.
Beyond still images, ComfyUI now drives video generation through models like Krea2 and LTX2, so it is no longer just an image tool. You can chain multiple models, mix custom and community nodes, batch-process, and export whole workflows as reusable JSON.
Pricing has two sides. The self-hosted software is completely free and open-source. The official Comfy Cloud managed service, which left beta and moved to a unified credit model in late 2025 before adding a free tier in March 2026, has a Free plan (400 credits/month, no card required), Standard at $20/month (4,200 credits), Creator at $35/month (7,400 credits, with LoRA import), Pro at $100/month (21,100 credits) and a custom Enterprise tier.
The main limitation is the learning curve. The node graph is powerful but intimidating for beginners, and running locally means managing GPU hardware, model files and dependencies yourself. Comfy Cloud removes the setup burden but ties usage to a credit budget.
Choose ComfyUI if you want deep, reproducible control over generation, are comfortable with a technical interface, or want the option to start free locally and move to a managed cloud later.
- Free and fully open-source when self-hosted, with no feature paywall on the core app
- Node graph gives precise, reproducible control and workflows are shareable as JSON
- Now covers both image and video models (Krea2, LTX2), not just still images
- v0.27.0 adds int8 quantized models and better LoRA/memory handling for efficient GPU use
- Optional Comfy Cloud, including a free 400-credit tier, removes local setup for those who want it
- Steep learning curve; the node interface is unintuitive for newcomers
- Self-hosting requires capable GPU hardware plus manual model and dependency management
- Comfy Cloud usage is metered by credits, which can run out on heavy workloads
- Quality of experience depends heavily on community custom nodes that vary in reliability
- int8 quantization benefits are limited to Turing-generation GPUs and newer
Choose ComfyUI if…
- You want granular, reproducible control over generation pipelines
- You are comfortable with a technical, node-based interface
- You need both image and video generation in one tool
- You prefer a free self-hosted setup but may want managed cloud later
- You want to build and share reusable JSON workflows
