Node-based visual AI studio for images, video, 3D and audio
Connect models, samplers, conditioning, LoRAs and output nodes on an infinite canvas where every step is visible and adjustable.
One interface for image generation, video, 3D assets and audio or music workflows, with support for leading open and partner models.
Run ComfyUI locally on your own GPU, or open the same workflows in the cloud when you don't have the hardware.
Deploy any workflow as a production API so your own app or agent can generate outputs on demand.

Describe your idea and Replit builds a working app in minutes
Describe the product you want and the agent plans, codes, tests and iterates on a working full-stack application.
Authentication, databases, hosting and monitoring work out of the box, so apps scale without separate DevOps work.
A no-cost mode lets you brainstorm and build without spending tokens before upgrading to stronger models.
Connect services such as OpenAI, Stripe and Google Workspace in minutes rather than writing glue code.
Delivers exceptional UI generation and full-stack app creation, but focuses less on traditional multi-language code editing than Replit.
#1
Provides a powerful AI-native desktop code editor for professional developers, but lacks Replit's instant browser-based cloud hosting deployment.
SpecialistProvides advanced agentic parallel coding workflows, but functions as a dedicated desktop/CLI environment rather than Replit's all-in-one cloud workspace.
#3
