[ EDITORIAL PICK ]
Why we recommend SwarmUI
- Open source
Source is public — you can audit it, fork it, and you'll never lose access to your workflows if SwarmUI the company changes direction.
- Runs on 8 GB
Comfortable on a mid-range consumer card — no need to remortgage for an A100.
- Apple Silicon
Native Metal / MPS support — runs on M-series Macs without CUDA gymnastics.
- Workflow engine
Composable nodes — chain models together instead of being stuck with a single fixed pipeline.
