Runner-up

Open Otter

杰 何$9.99

A serious power-user pick for the Local ML Model Workbench: it runs open models natively on Apple Silicon via MLX, exposes a drop-in OpenAI server, and even supports distributed multi-Mac inference. What sets it apart is the hardware monitoring dashboard, SSD-backed KV cache, and built-in on-device vector DB for RAG.

RectLabel

Ryo KawamuraFree

A best-in-class offline annotation tool for object detection and segmentation, exactly the kind of app Local ML Model Workbench exists for. It runs Segment Anything, Cellpose, and Core ML auto-labelers entirely on-device and exports to YOLO/COCO/CreateML/DOTA, making it a serious practitioner pick.
