Native support covers image models such as SDXL, SD3.5, Flux.1/Flux.2 and Qwen Image, image editing, video (Wan 2.x, LTX-Video, HunyuanVideo), audio and 3D. Queueing is asynchronous, only the changed part of a graph re-runs, and VRAM/RAM management with model offloading and quantized models lets big models run on modest cards. Reusable subgraphs, templates and App Mode turn a complex graph into a simple form, and the API slots a workflow into a production pipeline. Desktop app for Windows and macOS, manual install everywhere. ★~139k.","theCatch":"It is an engine you operate, not a one-click generator: node graphs have a learning curve, and the large custom-node ecosystem is third-party Python you are running with full access to your machine, so vet what you install. Real speed needs a decent GPU. Comfy Cloud and the partner nodes for closed models are paid; the local engine is free. GPL-3.0 matters if you plan to redistribute a modified build.","verdict":"The default local engine for generative media pipelines — keep custom nodes to ones you trust.","addedAt":"2026-10-19","featured":false,"domain":"AI Agents","subSpecialty":"Agents","subcategory":"Inference & Local Models","tags":["api","web-ui","self-host","copyleft","local-llm","voice","workflows","active","fast-stars"],"capabilities":["api"],"surfaces":["API","Self-host"],"ecosystem":["Multi-platform"],"licenseModel":"GPL-3.0","githubStars":138843,"starsPerWeek":709,"access":"free","archived":false,"repo":{"createdAt":"2023-01-17","pushedAt":"2026-10-19","license":"GPL-3.0","archived":false,"checkedAt":"2026-10-19"}},"related":[{"slug":"claude-code","name":"Claude Code","tagline":"Terminal-first coding agent with deep repository context"},{"slug":"cursor","name":"Cursor","tagline":"The AI-first code editor that understands your codebase"},{"slug":"devin","name":"Devin","tagline":"Autonomous AI engineer for defined engineering tasks"},{"slug":"stagehand","name":"Stagehand","tagline":"AI-native browser automation that mixes code and natural language"},{"slug":"browser-use","name":"Browser Use","tagline":"Open-source framework for LLM-driven browser agents"}],"links":{"self":"/api/gems/comfyui","html":"/gems/comfyui","markdown":"/gems/comfyui.md","category":"/api/gems?category=agents","categoryPage":"/stacks/agents"}}
