What is it?
Forge Neo is a web interface for generating images and videos with Stable Diffusion and related diffusion models. It is a fork of the Stable Diffusion WebUI Forge platform, continued from the last Gradio 4.40.0-based release of Forge and focused on optimization and usability through a browser-based GUI.
The project adds support for a range of recent models, including Qwen-Image, Flux.2-Klein, Z-Image, Wan 2.2 (14B), Krea 2, Anima, and Ernie-Image, along with ControlNet variants such as LLLite, Union and Region. It also includes multiple attention backends (SageAttention, FlashAttention, xformers, PyTorch), tiled VAE, torch.compile support, and a rewritten preset system that stores checkpoint and parameter selections.
Installation runs through a launch script, with optional uv-based package installation and command-line flags for memory management, model directory sharing with other UIs, and API access. Video export requires FFmpeg.
Key features

- 02Offers multiple attention backends including SageAttention, FlashAttention, xformers and PyTorch.
- 03Includes ControlNet variants such as LLLite, Union and Region.
- 04Provides a preset system that saves checkpoint and parameter selections.
- 05Supports sharing model folders with Automatic1111 or ComfyUI installations.
Use cases
- Running recent diffusion models such as Flux, Qwen-Image or Wan through a browser GUI.
- Generating short videos with Wan 2.2 on a local GPU.
- Reusing an existing Automatic1111 or ComfyUI model library without duplicating files.
Things to know
- Licensed under AGPL-3.0, a copyleft license that can restrict closed-source or commercial use.
