What problem it solves

Visual creators who rely on generative models often need direct control over which model, parameter and output they get, without giving up a local setup. Running large open models also typically demands more memory than consumer hardware offers, so workflows need to work within tight VRAM and RAM limits while remaining reproducible and scriptable.

Key features

• Visual node graph workflows — Workflows for image, video, audio, 3D and text generation are assembled as a visual graph of nodes, so they can be built and reused without writing code.

• Local execution on consumer hardware — Execution is designed around local machines, with asynchronous queueing, partial graph re-execution, smart VRAM and RAM management, model offloading and support for quantized models.

  Source: README

• Broad native model support — Image generation, editing, video, audio, 3D, vision and text models are supported natively, with checkpoints, VAEs, text encoders, LoRAs, ControlNets, adapters and upscalers loadable from supported formats.

• Automation and integration — Workflows can be reused as subgraphs and templates, exposed through App Mode or a local API, and saved or loaded as JSON for pipeline integration.

• Offline operation and extension — The core runs fully offline and downloads nothing unless asked, and the system can be extended with custom nodes and additional model search paths.

Who it may suit

This may suit visual professionals who want per-parameter control over generative models, and engineers who need a scriptable, local-first node graph to embed in production pipelines.

Topics to discuss

• Which model families or node types would you most like to see supported natively next?

• How should the graph format evolve so workflows stay portable across the desktop app, the local API and the cloud?

• What is the best way to keep custom nodes working across frequent weekly core releases?
